Abstract
Official abstract text for this publication.
A motor controller comprising multiple types of interfaces assigned automatically, including a mother circuit board and a daughter circuit board. The daughter circuit board is plugged into the mother circuit board to form electric connection. The mother circuit board has a power circuit, a microprocessor unit of the mother circuit board, a rotor position sensing unit, a power inverter unit, and an analog sensing unit. The daughter circuit board includes a signal interface circuit. The mother circuit board further has a serial digital communication unit. The signal interface circuit includes a microprocessor of the daughter circuit board, and a serial digital communication unit of the daughter circuit board. The microprocessor unit of the mother circuit board communicates with the microprocessor of the daughter circuit board via the serial digital communication unit of the mother circuit board and the serial digital communication unit of the daughter circuit board.
