Problems solved by technology
[0003] Due to dimensional tolerances between components and assembly processes, the distance between different motors and the distance between electronic components and motor covers can only be designed according to the worst heat dissipation conditions, resulting in requirements for the selection of electronic components High, and the heat dissipation is not good when the distance is large, which may cause the electronic components to burn out, which will cause the motor to fail to work normally, and the control board is unevenly stressed and easily deformed, which reduces the reliability of the controller

The invention generally relates to the technical field of motors. Specifically, the invention relates to a stator assembly and a motor. The stator assembly comprises a framework, a control circuit board movably installed on the framework and an elastic supporting piece arranged between the control circuit board and the framework. The moving direction of the control circuit board is the same as theelastic direction of the elastic supporting piece; the elastic supporting piece enables the control circuit board to have a certain moving range; when the motor is assembled, the motor shell extrudesthe control circuit board to move towards the framework; the elastic supporting piece is compressed, and the elastic supporting piece applies a counter-acting force to the control circuit board, so that the control circuit board is ensured to be attached to the motor shell; the elastic supporting piece is provided with a first supporting part and a second supporting part arranged on the side, facing the center of the framework, of the first supporting part, the first supporting part and the second supporting part are attached to the control circuit board, the supporting range of the control circuit board is enlarged, and the stability of the control circuit board is improved.
Description
technical field [0001] The present application generally relates to the field of motor technology, and in particular, relates to a stator assembly and a motor. Background technique [0002] The brushless DC motor is composed of the main body of the motor and the driver. It is a typical mechatronics product. Since the brushless DC motor operates in a self-controlled manner, it will not be in the rotor like a synchronous motor that is started under heavy load under variable frequency speed regulation. Adding a starting winding to the motor will not cause oscillation and out-of-step when the load changes suddenly. The controller of the brushless DC motor is installed and fixed on the stator insulating frame by buckles or screws on the insulating frame. The electronic components are in contact with the motor cover and dissipate heat through the motor cover. [0003] Due to dimensional tolerances between components and assembly processes, the distance between the electronic comp...
