Abstract
A motor controller includes a tap position selection circuit, a micro control unit (MCU), and an inverter circuit. The tap position selection circuit is configured to process a plurality of tap position signals transmit processed tap position signals to the MCU. The MCU is configured to output signals to control the operation of the inverter circuit. The inverter circuit includes an output terminal connected to a plurality of coil windings of a stator module of a motor. The tap position selection circuit includes a plurality of first signal input circuits for motor start and a plurality of second signal input circuits for motor stop; each tap position signal is split into a first part and a second part. The first part is input into one first signal input circuit for motor start and the second part is input into one second signal input circuit for motor stop.
