Abstract

PURPOSE: To prevent the abrasion of the contact and the occurrence of the noise, by employing a switching element comprised of a capacitor, charge/discharge circuit of said capacitor, and first and second AC control elements.
CONSTITUTION: Upon closing of relay contact K, bias is applied on the gate electrode G1 of AC control element Q1 to turn it on and to rotate the motor M. While at the same time capacitor C1 is charged through diode D1. Here AC control element Q2 is turned off. Upon opening of relay contct K, AC control element Q1 is turned off to block the voltage supplied to the motor M, while AC control element Q2 is turned on to discharge the capacitor to motor M side. Consequently the motor is braked to stop
