The existing drive and control integrated motor consists of a motor body and a backpack drive and control module, and the motor body and the backpack drive and control module are connected and fixed together through a fixed position determined on a die, wherein the motor body consists of a rotor, a wire stator, a front end cover, a machine base, a rear end cover, fan blades and the like, bolts fix the motor body and the machine base through lugs on the outer surfaces of the end cover and the machine base, the outer wall of the motor body forms a heat dissipation rib, and when the motor works, the fan blades of the motor body rotate to generate wind to take away heat along the direction of the heat dissipation rib.

Because the outer wall of the motor body forms the heat dissipation ribs, under the limitation of the central height of the motor, the volume of the cavity inside the base is reduced, and at the moment, the outer circle of the inner wire stator is correspondingly reduced, and under the condition of the concentric height, the motor power cannot be improved or is difficult to be improved due to the limitation of the wire stator.
