Abstract
A motor controller comprises a switch circuit, a control unit, and a duty cycle processing unit. The switch circuit is coupled to a motor for driving the motor. The control unit is configured to generate a plurality of control signals to control the switch circuit. The duty cycle processing unit receives a first pulse width modulation signal, where the first pulse width modulation has a first duty cycle. The duty cycle processing unit is configured to judge if the first duty cycle is equal to 0% or 100%. The duty cycle processing unit comprises a duty cycle computing unit, where the duty cycle computing unit is configured to capture the first duty cycle.
