Preferably, described motor body is an external rotor electric machine, comprises external rotor, stator, and stator is positioned at rotor, and rotor directly drives driving shaft, and stator has inner diameter volume, and transmission device is installed in the diameter of stator bore space.
Preferably, described transmission device is fixedly mounted in the diameter of stator bore space by installing component.
Preferably, described installing component is a screw.
Preferably, described rotor comprises the rotor retainer, and the rotor retainer is fixedlyed connected with described driving shaft by shaft joint.
Preferably, described transmission device comprises gear box and clutch, and driving shaft is by gear and gear box engagement.
Preferably, driving shaft be set with outward can with the propeller shaft sleeve of its coaxial rotation, clutch is connected with propeller shaft sleeve respectively with gear box.
Preferably, described transmission device also comprises housing, and gear box and clutch device fit in the housing, and described housing becomes the stator retainer, and stator is fixedlyed connected with the stator retainer.
Preferably, gear box and clutch are assemblied in the housing by engagement system.
