ABSTRACT:
A drive control device for a brushless motor includes a full-wave rectifying-filtering circuit, a voltage regulating circuit, a drive control circuit and a protection circuit. A combination of the rectifying-filtering and voltage regulating circuit provides both the motor coil and the drive control circuit capable of operating at a normal working status to ensure the brushless motor with safe and reliable operation. Therefore, the brushless motor does not need a bulk and complex transformer for voltage drop, which may reduce the reliability of the operation.
