摘要： A motor controller, including: a Bluetooth communication unit and a motor control unit. The Bluetooth communication unit includes: a power supply part, a Bluetooth module, and an interface circuit. The motor control unit includes an input port of a rotational speed adjusting signal. The power supply part supplies power to the Bluetooth module and the interface circuit. The Bluetooth module enables the motor control unit to communicate with an external device. The Bluetooth module inputs a PWM signal into the input port of the rotational speed adjusting signal of the motor control unit via the interface circuit.
