Abstract

A motor controller having a pulse width modulation generating mechanism is provided. A triangular wave signal generator circuit generates a triangular wave signal. A comparator compares the triangular wave signal with an input control signal to determine a pulse width modulation signal. A signal detector circuit detects a duty cycle of each of a plurality of pulse waves of the pulse width modulation signal. A control converter circuit converts the duty cycle of each of the plurality of pulse waves of the pulse width modulation signal as an arithmetic value into a control value, according to a preset ratio. A driver circuit drives a motor to rotate according to the control value from the control converter circuit.
