Integrally structured motor and controller assembly

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...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: since the motor and the controller used in the electric vehicle in the prior art are of separate structure, the production cost of the motor and the controller is high, the efficiency is low, and the problem of false return is easy to be caused. The invention provides a motor and controller assembly with an integrated structure to solve the above problems
