  • Control Of Motors That Do Not Use Commutators (AREA)

Abstract

PURPOSE: To switch a control advancement angle without fluctuating the torque of a commutatorless motor when shifting the motor from a low speed to a high speed, by regulating the input current to a separately-excited conversion circuit depending on a current level instruction applied from a current instruction circuit to a current regulation circuit.
CONSTITUTION: When the commutatorless motor 20 is started, namely, slowly rotated, a motor control advancement angle is set at a small value and the output of a monostable multivibrator 40 is "0". At that time, switching elements S1, S2 are open and a speed control circuit 30 generates a current command i* corresponding to the speed deviation of the motor. When the motor is shifted from the low speed to the high speed and the motor control advancement angle is switched, the switching elements S1, S2 are closed for a prescribed time and the output of the speed control circuit 30 is forcedly set on the output of a non-linear circuit 36 which produces the output corresponding to the current of the motor. The control advancement angle can thus be switched without fluctuating the torque of the motor.
