ABSTRACT:
A control system for a brushless motor is disclosed which comprises an AC power supply, a rectifier circuit including controlled rectifier elements for converting the alternating current supplied by the AC power supply into a direct current, an inverter circuit including controlled rectifier elements for converting the direct current produced by the rectifier circuit into an alternating current, a motor driven by the inverter circuit and a position detector for detecting a signal representing rotational positions of the motor. The controlled rectifier elements of the inverter circuit are fired in predetermined sequence in response to detection signals from the position detector, while the DC output current of the rectifier is continually controlled at each commutation of the inverter circuit at low motor speeds. A predetermined number of signals in synchronism with each commutation of the inverter circuit are included in one cycle, so that the DC output current of the rectifier circuit is controlled for continual operation by the use of signals with different delay times behind the aforementioned signals concurrent with the commutation of the inverter.
