When we design or replaced the magnetic contactor for motor starter or for others application,the important point is how to sizing the size of magnetic contactor.This is critical point because if we not sizing properly,it can cause a serious damage and our application maybe failure to perform in perfect condition.
This time i want  shared some information and basic technique how to sizing the magnetic contactor with properly method and suitable with our application needed.It is to ensure our application design is correctly function and have a good resulted. The Main Contact have a rating to allowed some of current value ( ampere ) to through it.The current rating depend on the type of application. 3) AC3 – Starting of squirrel-cage motors and switching off only after the motor is up to speed.

The motor used in these mowers is the exact kind of motor you'd expect to find in a tredmill.
Circuit #1 controlled by the switch is the connection of the AC "hot" wire to the bridge rectifier. Based on my family's experiences with our 3 electric mowers, it appears that these models are prone to 2 types of failures: switch assembly failure or bridge rectifier failure.
Researcher Stephanie Ameis reported at the 2015 meeting of the American Academy of Child and Adolescent Psychiatry that following repeated transcranial magnetic stimulation (rTMS), a treatment in which a magnetic coil placed over the scalp delivers electric pulses to the brain, children with schizophrenia and autism spectrum disorders showed improvements in executive function, including working memory.
Repeated transcranial magnetic stimulation (rTMS) is a treatment for depression in which magnets placed near the skull stimulate electrical impulses in the brain. In the study, 27 patients in an episode of major depression underwent magnetic resonance brain scans before and after receiving rTMS treatment over their left prefrontal cortices. The brain changes were not correlated with antidepressant response to rTMS, but suggest a possible mechanism by which rTMS is effective in some people. At the 2015 meeting of the Transcranial Magnetic Stimulation Society, Linda Carpenter, an American researcher who specializes in repeated transcranial magnetic stimulation (rTMS), a method of treating depression by using a magnetic coil placed near the scalp to stimulate neurons, compared notes with Jeff Daskalakis, a Canadian researcher who also studies rTMS. In contrast, Daskalakis and his Canadian colleagues can and do use rTMS to treat a broader range of illnesses including bipolar disorder.
At the 2015 meeting of the Society of Biological Psychiatry in May, researcher Daniel Blumberger reported to this editor (Robert M. Blumberger has also successfully used rTMS as a followup treatment to a successful course of electroconvulsive therapy (ECT), administering rTMS twice a week for up to 66 treatments in a given patient in order to maintain remission of their depression. At the 2015 meeting of the Transcranial Magnetic Stimulation Society, researcher Joseph Zohar presented evidence that deep transcranial magnetic stimulation (deep TMS) targeted over the medial prefrontal cortex may reduce OCD symptoms. In addition to the deep TMS procedures, all patients also received cognitive behavioral therapy, high doses of SSRIs, and relapse prevention training.
Editor’s Note: It is interesting that 20 Hz deep TMS, which activates the prefrontal cortex, was more effective than 1 Hz, which decreases activity there. At the 2015 meeting of the Transcranial Magnetic Stimulation Society in May, researcher Stephanie Ameis discussed the dearth of medication studies in children, particularly for depression but also for schizophrenia and autism spectrum disorders, which share the symptom of impaired executive functioning, which can include skills such as planning and problem solving. Ameis noted that in a literature review, there were a total of 1046 controlled pharmacological treatment studies in adults compared to only 106 in children, which reflects a relative absence of treatment knowledge, especially for depression (where there were 303 studies in adults versus only 17 in children) and bipolar disorder (where there were 174 studies of adults and 24 of children).
At the 3rd Annual Meeting of the Transcranial Magnetic Stimulation Society, Canadian researcher Frank MacMaster discussed his study of repeated transcranial magnetic stimulation (rTMS) in 50 children with depression. MacMaster hopes that glutamate levels and other biological indicators such as inflammation will eventually pinpoint which treatments are likely to work best for children with depression. At the May meeting of the Society of Biological Psychiatry, researcher Deborah Kim gave a talk on the use of repeated transcranial magnetic stimulation (rTMS) for depression in women who are pregnant. RTMS offers an alternative to women who are reluctant to take antidepressants during pregnancy.
Editor’s Note: For mild depression during pregnancy, exercise and psychotherapy might be optimal, along with folate and vitamin D3. At the 3rd Annual Meeting of the Clinical TMS Society this past May, this editor (Robert M. RTMS is a non-invasive procedure in which a magnetic coil placed near a patient’s head delivers electrical currents to their brain. RTMS might enhance extinction learning, or the breaking of a habitual way of thinking, as it stimulates the media prefrontal cortex, a critical area for new learning.
It may also be possible to use rTMS in conjunction with medications (such as valproate) that affect epigenetic changes on the histones around which DNA is wrapped (because valproate is a histone de-acetylase inhibitor, preventing the removal of acetyl groups from the histones and allowing them to be transcribed more easily). One could also envision using rTMS to enhance learning during the memory re-consolidation window that opens 5 minutes to an hour after a person actively recalls old memories, and which can lead to more permanent memory alterations in anxiety disorders, post-traumatic stress disorder (PTSD), and substance abuse. Since patients are awake and able to talk during rTMS, making use of evoked thoughts and memories specifically for a given patient may lead to enhanced clinical effects, because these neural pathways are more selective activated and potentiated, leading to what is called experience-dependent neuroplasticity. Regulation of the amygdala (the brain’s emotional center), particularly through its interaction with the ventral anterior cingulate cortex, has been implicated in the experience of fear in animals, and anxiety and depression in humans. The researchers’ study used single-pulse probe TMS delivered at a rate of 0.4 Hz at 120% of each participant’s motor threshold, targeted at the anterior or posterior medial frontal gyrus on either side of the brain.


RTMS to the right side of the medial frontal gyrus increased connectivity between the amygdala and the ventral anterior cingulate cortex more than stimulation to the left side. Editor’s Note: These data indicate that rTMS can alter brain activity in these deeper regions and can influence inter-regional connectivity.
Although the editors of BipolarNews.org have made every effort to report accurate information, much of the work referenced here is in abstract or pre-publication form, and may not have received proper review by the scientific community at this time. The AC-DC conversion is accomplished through the use of a bridge rectifier, which is simply 4 diodes crammed into a box.
The 4 lines running through the dashed line represent the wiring harness that runs from the switch assembly down to the mower deck.
Heat is the most likely thing to destroy the rectifier since it doesn't have a very large heat-sink and is located right next to the motor (which can get quite hot during operation). The recifier is mounted in the upper-center of the mower, just adjacent to the motor (see photos below). These factory parts sell for over $10, which is kind of ridiculous since these are such common parts that are available from almost any electronics supplier.
In a poster presented at the 2015 meeting of the Society of Biological Psychiatry, Martin Lan and colleagues presented results of the first study of structural changes in the brain following rTMS. Lan and colleagues reported that several cortical regions related to cognitive appraisal, the subjective experience of emotion, and self-referential processing increased in volume following rTMS treatment: the anterior cingulate, the cingulate body, the precuneous, right insula, and gray matter in the medial frontal gyrus. Lan and colleagues concluded that rTMS likely had neuroplastic effects in areas of the brain that are important for emotion regulation.
RTMS has been approved by the Federal Drug Administration for the treatment of unipolar depression under very limited parameters (only at a frequency of 10Hz).
In Canada rTMS is used to treat unipolar depression, schizophrenia, post-traumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD), and clinicians can adjust the parameters to treat adolescents and the elderly. Because rTMS has not been approved for the treatment of bipolar disorder, Carpenter and other clinicians in the US are unable to treat bipolar depression even though a wide range of experts and published studies report that rTMS is as effective (or possibly even more so) for patients with bipolar depression than for those with unipolar depression. The discrepancy is even sadder when one considers that there are already more than 20 FDA-approved antidepressants that can be used to treat unipolar depression, but only three approved medications for bipolar depression. Post) that he has found repeated transcranial magnetic stimulation (rTMS) to be effective for depression in late life.
Selective serotonin reuptake inhibitor (SSRI) antidepressants are the most commonly used treatment for OCD, but not all patients respond adequately to them. In TMS treatment, an electromagnetic coil is placed against the patient’s head and magnetic pulses that can penetrate the scalp are converted into small electrical currents that stimulate neurons in the brain. Other attempts to treat OCD have focused on suppressing frontal-striatal-thalamic circuits, which are overactive in the disorder.
She identified several series with only a total of 33 children and adolescents who had been treated with rTMS.
RTMS is a non-invasive procedure in which an electromagnetic coil is placed against the side of the forehead and magnetic pulses that can penetrate the scalp are converted into small electrical currents that stimulate neurons in the brain. At the meeting, MacMaster said that in Canada, only a quarter of the 1,200,000 children with depression receive appropriate treatment for it. MacMaster noted that this type of research is possible due to the phenomenal improvements in brain imaging techniques that have occurred over the past several decades. In rTMS treatment, an electromagnetic coil is placed against the side of the forehead and magnetic pulses that can penetrate the scalp are converted into small electrical currents that stimulate neurons in the brain. For moderate depression, omega-3 fatty acids might also be helpful, but it now appears that rTMS would be less risky than electroconvulsive therapy (ECT), which in the past has been a typical recommendation for pregnant women, but which exposes the fetus to the effects of anesthesia and seizure.
Post) discussed remission rates for repeated transcranial magnetic stimulation (RTMS), which at 30% leave room for improvement. D-cycloserine, a partial glutamate agonist, has been shown to enhance extinction, and since rTMS releases glutamate and BDNF, it might also do the same. Valproate enhances extinction learning in animals, so the stimulation of the medial prefrontal cortex and the increase in BDNF and glutamate that occur with rTMS may interact to potentiate this extinction learning. The researchers also used functional magnetic resonance imaging (fMRI) of the whole brain to observe connectivity between different sections. Stimulation of the posterior portion of the medial frontal gyrus increased connectivity more than stimulation of the anterior portion. This is important because abnormalities in the connectivity of brain regions have increasingly been found in patients with mood disorders.
The electrical system consists of only 3 parts: the motor, the switch assembly, and a standard bridge rectifier. The motor is a brushed, permanent-magnet DC motor, which is designed to run at about 120 Volts DC. The rectifier used in most of these mowers is in an MB or GBPC package, having 4 "faston" connectors for the wiring and a single screw hole in the center for mounting to a heatsink.


This means that the switch controls two separate circuits and when circuit #1 is "on", circuit #2 is "off", and vice-versa. That's right, when Circuit #2 is "on", it is purposely creating a short-circuit across the motor terminals. This is a function of age and is somewhat expected given the high current flowing through what appears to be a mediocre switch. Bipolar depression is an orphan illness, which lacks a powerful voice advocating for more treatment research about optimal therapeutic strategies.
In Zohar’s study, patients with OCD were randomized to receive deep TMS at frequencies of either 20 Hz or 1 Hz, or a sham procedure. Since the medial prefrontal cortex is an important area for the new learning required for the extinction of anxiety symptoms in a variety of disorders, increasing activity in this medial prefrontal target area with 20 Hz may activate that extinction process allowing new learning rather than nonspecifically suppressing hyperactive frontal-striatal-thalamic circuits as 1 Hz TMS would do.
She is beginning to study rTMS in patients with high-functioning autism (40 patients aged 16 to 25 have been randomized in her study). The study was designed to identify biomarkers, or characteristics that might indicate which patients were likely to respond to the treatment. Very little funding is devoted to research on children’s mental health, a serious deficit when one considers that most depression, anxiety, attention deficit hyperactivity disorder (ADHD), bipolar disorder, oppositional behavior, conduct disorder, and substance abuse begins in childhood and adolescence, and early onset of these illnesses has been repeatedly linked to poorer outcomes. Kim had recently completed an open study of rTMS in pregnant women, in which 70% of the women responded to rTMS. Cohen and colleagues in which women taking antidepressants show a 68% relapse rate if they stop taking these medications during pregnancy compared to a 26% relapse rate among those who continue taking antidepressants during pregnancy.
In her summary Kim recommended that women with a pattern of recurrent depression continue antidepressant treatment, especially since a mother’s depression itself poses non-trivial risks to the fetus. It may be possible to personalize treatment parameters to achieve better success in individual patients. If this is not possible, patients who fail to respond to one frequency might be switched over to the other frequency. Repeated transcranial magnetic stimulation (rTMS) is a method of stimulating outer regions of the brain with magnets. Oathes and Etkin hope that these findings can be applied to others and that rTMS can be used to correct patterns of regional connectivity in the brain in order to improve emotion regulation.
Although they have provided years of good service, like all products they have their weaknesses. Additionally, the switch has an area about mid-travel where both circuits are "off" to prevent a short-circuit through the bridge rectifier. Per the wiring diagram shown above, there are 2 AC connections, marked by ~, and 2 DC connections, marked + and - respectively.
Providers face  scrutiny of study recruitment practices and recordkeeping by insurers and the Joint Commission (formerly the Joint Commission of Accreditation of Healthcare Organizations), which assesses healthcare quality. The 20 Hz deep TMS resulted in a 28% reduction in OCD symptoms compared to the other two groups, indicating that the 20 Hz treatment had a large effect size. Ameis also described a 2013 study of rTMS in which patients with schizophrenia showed improved performance on a test of working memory published by Mera S. These methods provide exquisite views of the living brain, the most complicated structure in the universe. In another controlled randomized study of 30 women (also by Kim), 75% responded to active rTMS and 50% responded to a sham procedure. Researchers Desmond Oathes and Amit Etkin are investigating whether rTMS can also be used to influence these deeper brain areas, or their interaction with each other. This is done because it is desirable for safety reasons to have the motor stop spinning as soon as possible after the handle switch is released.
Using magnetic resonance spectroscopy (MRS) technology, MacMaster found that children who responded well to rTMS treatment had low levels of the neurotransmitter glutamate at the beginning of the study, but their glutamate levels increased as their depression improved.
The biomarkers these techniques may identify will allow clinicians to predict how a patient will respond to a given treatment, to choose treatments more rapidly, and to treat patients more effectively. Kim summarized the literature on antidepressants in pregnancy, concluding that there is a preponderance of evidence that antidepressants are safe for the mother and fetus, with few serious effects having been observed.
Though, the method of dead-shorting the motor to implement plug-braking is questionalbe, it works.
Ameis cited this as a rationale for studying rTMS’s effect on cognitive performance in people with autism.
Children who didn’t improve had higher glutamate levels at the beginning of the study, and these fell during the rTMS treatment.
