The use of self-induced emf achieve instant protection circuits


Posted on Mar 28, 2007

Circuit shown in Figure 3-73. The line is to use the power of instantaneous power failure, the self-induced emf generated by the motor to implement now instant shutdown protect

ion. When momentary power outage, contact KM loss of power release, power machine for inertial rotation, while KM normally closed auxiliary contact is closed, the motor V, W and white self-induced emf through diode VD to the DC relay is powered KA. KA is energized, the normally open contact closure, if it when the power supply has been restored, the contactor KM obtain electric suction combined self- locking, the motor re-connect the power running.
