CIRCUIT FOR MULTI-SPEED TWO-PHASE MOTOR |
摘要 |
This circuit utilizes an RLC network, using the motor winding as a component, to alter the speed of an ac two-phase servo motor. The RLC circuit produces a dc component and variable frequency ac component which effectively produce a signal on the control winding of the motor. Power for the RLC network is taken from the ac line through a rectifier (diode).
