Problems solved by technology

Although the function of protecting the controller is realized to avoid damage from water or dust or other factors, the air circulation is poor and the heat dissipation effect is limited. It is necessary to set up a complex heat dissipation structure on the end cover to meet the controller's requirements. High heat dissipation requirements, high technical difficulty, high heat dissipation cost, and the combination of shell cover plate and shell base further increases manufacturing or processing costs
Therefore, although the existing integrated motor and controller assembly has improved the structural compactness to a certain extent, because the radiator and the protective shell are two independent parts, it still occupies a large installation space and the structure is not compact enough. The manufacturing cost of the protective shell formed by the combination of the cover plate and the shell base is relatively high
[0004] In addition, the motors in the prior art have various technical problems in the stator assembly, the rotor assembly, and the distribution of stator windings. high manufacturing cost

Abstract

The invention relates to a motor and controller assembly. The motor and controller assembly comprises a motor and a controller which controls the running of the motor, wherein one side of the controller is fixedly arranged at the outer side of an end cover, a heating element of the controller is arranged on a controller panel closing to the outer side of the end cover, a matching component which is fixedly connected with the heating element is arranged at the outer side of the end cover, the heating element is fixedly connected with the matching component, and the end cover is prepared by the material with high heat conductivity coefficient. According to the motor and controller assembly disclosed by the invention, by directly and fixedly matching the heating element of the controller with the end cover of the motor, the situation of simultaneously using the end cover which is prepared by the material with the high heat conductivity coefficient as a heat radiator of the controller is realized, the heat radiating requirement of the heat radiator can be met, the structure compact degree of the motor and controller assembly is greatly increased, the independent arrangement of the heat radiator is avoided as well, and the production cost is greatly lowered.
