Abstract
The provided are a brake-by-wire (BBW) electronic control actuator unit and a use thereof. The BBW electronic control actuator unit includes a machine body, as well as a permanent magnet brushless direct-current motor (PMBDCM) and speed-reducing torque-increasing gear sets integrated in the machine body, where the PMBDCM includes a stator assembly and a rotor assembly; the rotor assembly is connected to one end of a motor shaft; the other end of the motor shaft is connected to an input end of each of the speed-reducing torque-increasing gear sets; an output end of the speed-reducing torque-increasing gear set is connected to an output shaft; and the output shaft extends out of the machine body. According to the BBW electronic control actuator unit and the use thereof, by assembling the PMBDCM and the speed-reducing torque-increasing gear set, there are advantages of a high mounting accuracy, and a compact structure.
