The invention discloses a built-in electric automobile wheel hub motor, and the motor comprises a hub motor, a braking disc, and a shaft sleeve. The front end of the hub motor extends to form a motor shaft, and an end face of the extending end of the motor shaft is provided with a braking disc installation platform. The braking disc is installed on and connected to the braking disc installation platform. The front end of the motor shaft is sleeved by the shaft sleeve, and the shaft sleeve is provided with a fixed piece. An inner end face of the shaft sleeve is provided with a key slot, and the rear end of the key slot is provided with a through hole. The through hole passes through the key slot, and the front end of the shaft sleeve is fixedly connected to a rear axle of an automobile. Through the above mode, the motor can reduce the weight of the automobile body, is simple in link mode, prolongs the driving distance of the automobile, directly drives a wheel hub, reduces the mechanical friction, improves the efficiency, is low in noise during driving, greatly improves the driving comfort, and is high in direct drive accelerating performance.
