Abstract
PURPOSE: To surely start a commutatorless motor without fluctuating its torque, by starting the commutatorless motor by another motor.
CONSTITUTION: Contacts RY1∼RY6 are opened and a contactor 21 is closed to drive an auxiliary motor 20 to start the commutatorless motor 6. When the commutatorless motor 6 reaches a prescribed speed, the contact RY6 is closed to read the speed of the motor 6 into a ramp function circuit 8. When the commutatorless motor 6 reaches such a speed that a sufficient voltage is induced, the contact RY6 is opened and the contacts RY1, RY3 are closed and a power rectifier 1 is driven to control the speed of the motor 6. In the load on the commutatorless motor is heavy, the auxiliary motor 20 may be used to produce an accessory output. If a motor is directly coupled to the rotary shaft of the load, the motor and a turn-on circuit can be used instead of the auxiliary motor and the contactor.
