Example Embodiment

[0028] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0029] Such as Figure 1~6 As shown, the present invention provides an integrated motor and controller assembly, including:

[0030] The motor housing includes a motor side cover 2 and a front end cover 1 covering the front end of the motor side cover 2. The front end cover 1 is provided with three first threaded holes 11 and three second threaded holes 12 along the circumferential direction, The three first threaded holes 11 and the three second threaded holes 12 are alternately and evenly distributed on the edge of the front end cover 1 in the circumferential direction. There is a cylindrical first cavity inside the motor housing, and the stator, The rotor and...

Abstract

The invention provides an integrally structured motor and controller assembly. The integrally structured motor and controller assembly includes a motor shell. The rear end of the motor shell is open, and a cylindrical first cavity is formed in the rear end of the motor shell. A stator, a rotor and a motor shaft are installed in the first cavity. A plurality of first threaded holes and a plurality of second threaded holes are formed in the motor shell in the circumferential direction. The integrally structured motor and controller assembly is concise and compact in structure; a motor part and a controller part are next to each other, so that the usage number of cables and the usage number of plug-in connectors are reduced; accordingly, the production cost is reduced, and production efficiency is enhanced; furthermore, as the cables are free of exposed parts basically, the situation that the exposed parts of the cables make contact with a compartment, so that the exposed parts of the cables are abraded, damaged and corroded by rainwater is avoided, and the failure rate is lowered; due to the integrated structure, the assembly can be returned to a manufacturer for repairing in a unified mode when the motor or the controller has a failure, the situation of returning by mistake will not occur, and then the after cost of the manufacturer is also greatly lowered.

Description

technical field [0001] The invention relates to the technical field of motor and motor control, in particular to an integrated motor and controller assembly. Background technique [0002] At present, electric bicycles, motorcycles and tractors mostly use brushless DC motors. The functions of brushless DC motors such as speed regulation, undervoltage protection, motor overcurrent protection, brake power failure, and power display rely on Hall sensors and controllers. Realization; now the motors and controllers in most electric vehicles are installed separately in different positions of the car body, and the motors and controllers need to be connected with longer cables and more plug-ins, which will not only increase production costs and Reduce production efficiency, and the exposure of the cable box plug-in is susceptible to wear and water corrosion, resulting in a high failure rate; a very real problem, due to the limitations of objective conditions and human factors, th...
