Motor controller assembly

The utility model provides a motor controller assembly, and relates to the technical field of motor controllers. According to the technical scheme, the motor controller assembly comprises the controller shell, the controller, the controller cover plate and the damping structures arranged at the mounting holes in the four corners of the controller shell, part of functional structures such as a low-voltage connector, a Hall plate and a wire holder in the motor controller are integrated, the space is saved, and the cost is reduced. The internal structure of the motor controller is simplified, and the system cost of the motor controller is reduced; secondly, according to the technical scheme, part of functional structures of the motor controller are integrated, the space of the motor controller is released, a heat dissipation water channel structure, a damping buffer structure and the like are additionally arranged in the space, the stability and reliability of the motor controller are improved, and therefore the
