Abstract
The invention discloses a motor controller which comprises a control unit, a voltage sampler, a current sampler, a speed controller interface unit, a function interface unit, a power source transformation unit, a motor coder and a motor power control unit. The motor coder transmits the magnetic pole position and motor turning angle signals of a motor to the control unit. The voltage sampler and the current sampler respectively collect voltage signals and current signal on a motor wire. A control power supply adjusts motor running by outputting pulse-width modulation (PWM) signals according to the voltage signals and the current signals respectively collected by the voltage sampler and the current sampler. The speed controller interface unit supplies an interface to a speed controller of the motor and transmits speed regulation signals of the control unit to the speed controller. The function interface unit is electrically connected onto the control unit. The power source transformation unit supplies 5V or 15V direct-current power sources to the controller. The motor controller achieves the purpose of accurately and fast controlling motor speed changing.
