METHOD OF CONTROLLING FIELD OF SHUNT MOTOR AND SHUNT FIELD DEVICE |
摘要 |
A motor control is provided for a DC series motor operative with a chopper apparatus and including a thyristor switch to determine the field shunt operation of the motor. A voltage reversal that occurs across the field windings when the chopper is OFF and not conducting is utilized to commutate and enable modulation of the field shunt thyristor switch as desired in relation to the chopper ON and OFF operation. |
