Abstract

PURPOSE: To start and rotate at low speed a commutator motor against large load torque at the motor starting time by providing a contact for bypassing a variable resistor of a first time constant circuit consisting of a resistor, the variable resistor and a capacitor via a relay of a second time constant circuit for predetermined time in parallel with the variable resistor.
CONSTITUTION: A circuit for bypassing a variable resistor VR by connecting a first time constant circuit to first and second anodes of a switching element Q and the normally open contact Rya of a realy Ry to both terminals of the variable resistor VR. A series circuit of the coil of the relay Ry and a capacitor C2 is connected across a zener diode ZD1 to thereby form a second time constant circuit to thus instantaneously operate the relay via constant DC voltage converted via the diode ZD1 to thereby complete charging of the capacitor C2 after predetermined time via the CR time constant of the resistance of the relay Ry and the capacitor C2 to thus reset the operation of the relay. Thus it can start and rotate at low speed a commutator motor against large load torque.
