Thermally suppressing circuit for restarting a locked motor with a restart-discharging drive member

摘要

A thermally suppressing circuit mainly comprises a restart-discharging drive member, a coil set, a restart-discharging capacitor, and a discharging switch set. The restart-discharging drive member is electrically connected to the coil set and the restart-discharging capacitor while the discharging switch set connected between the coil set and the restart-discharging capacitor. The discharging switch set is used to access signals output from the restart-discharging drive member. In abnormal operation, as the restart-discharging drive member may turn on an auto-restart function to output a high or low voltage signal, the discharging switch set is turned on to accelerate discharging the restart-discharging capacitor to thereby avoid overcurrent passing the coil set.
