Abstract
A motor controller is configured to stabilize the motor current. The motor controller is used for driving a motor. The motor controller comprises a switch circuit, a control unit, and a phase detecting unit. The phase detecting unit generates a phase signal to the control unit for switching phases. The phase signal sequentially generates a first, second, third, fourth, fifth and sixth time interval. The first to sixth time intervals correspond to first to sixth phases, respectively. The motor controller further comprises a first driving time for driving the motor in the fifth phase, where the first driving time is related to the first time interval. The motor controller further comprises a second driving time for driving the motor in the sixth phase, where the second driving time is related to the second time interval.
