Speed control circuit for a brushless dc motor |
摘要 |
A speed control circuit for a brushless dc motor includes a motor drive circuit, a drive member and a PWM control circuit. The motor drive circuit includes at least one coil and at least one transistor serially connected to the coil. The drive member is provided with a plurality of output terminals adapted to output a driving signal to the transistor of the motor drive circuit. The PWM control circuit is in connection between the transistor of the motor drive circuit and the output terminal of the drive member, thereby turning the transistor on or off.
