METHOD AND CIRCUIT FOR DC MOTOR FIELD REGULATION WITH SPEED FEEDBACK |
摘要 |
<p>METHOD AND CIRCUIT FOR DC MOTOR FIELD REGULATION WITH SPEED FEEDBACK A method and a circuit for motor field regulation in the constant horsepower speed range, wherein the weakening of field current allows operation of the motor at speeds higher than the base speed while maintaining rated armature voltage. The field current is weakened in response to speed feedback signals to provide a rapid response in controlling field current. The motor field is also regulated in response to a counter-EMF and IR compensation circuit to further weaken the field current, where the counter-EMF developed in the DC motor would cause excessive voltage across the armature.</p> |
