SPEED CONTROL OF SYNCHRONOUS MOTORS |
| 摘要 |
In a speed control system of a synchronous motor, a pulse modulated signal containing a signal representing rotational angle of the motor is formed to control the speed. The pulse modulated signal is passed through a synchronous rectifier to obtain currents supplied to stator windings of the motor. |
