Abstract

See full text

A motor controller circuit having a rotational speed locking mechanism is provided. Each time when a motor commutates, a first signal generating circuit resets a first waveform signal and a second signal generating circuit resets a second waveform signal. An output signal generating circuit outputs a waveform output signal according to the first waveform signal and the second waveform signal. A motor controller circuit outputs an on-time signal according to the waveform output signal. A motor driving circuit outputs a driving signal to the motor to drive the motor to rotate according to the on-time signal.
