Problems solved by technology
[0005] 1. The controller and the motor are integrated, and the space utilization rate is relatively low;
[0006] 2. The controller is integrated with the motor, which is large in size, requires high installation accuracy, and is difficult to install;
[0007] 3. Most of the water-cooled heat dissipation methods of the controller adopt a flat structure, and the power module is installed on one side of the radiator, which has low heat dissipation efficiency and is not conducive to the miniaturization and weight reduction of the motor controller

The invention discloses an electric drive system integrated with a motor and a controller, comprising a motor and an electric drive system housing (11) outside the motor, the electric drive system housing includes a mounting surface in the middle and two ends radially extending outward The electric drive system rear end cover (20) and the electric drive system front end cover (30), the motor front end is provided with the motor front end cover (3) installed on the electric drive system front end cover (30), the motor output shaft (4) from The motor front end cover (3) protrudes; the electric drive system housing (11) includes various components on which the controller is installed on the mounting surface in the middle, the electric drive system rear end cover (20) and the electric drive system front end cover (30 ) is installed between the extensions of the controller cover (2); the electric drive system housing and the motor front end cover (3) are provided with a cooling system. The controller of the present invention shares the water channel and the housing with the motor, which is small in size and highly integrated; the heat dissipation water channel adopts a double-sided cooling structure, and the power module and capacitor are arranged on one side of the water channel, and the motor stator is arranged on the other side, so that the heat dissipation effect is good.
Description
technical field [0001] The motor and the controller of the present invention particularly relate to an electric drive system integrating the motor and the controller. Background technique [0002] The currently visible integration of the motor and the controller mostly adopts the integration of the motor and the controller, the integration of the motor end cover or housing with the controller housing, or the integration of the motor and the controller by screw fastening. [0003] Most of the current water-cooling heat dissipation methods for motor controllers use a flat-plate structure. The usual practice is to install power devices on one side of the radiator, while the other side of the radiator is not fully utilized. [0004] Disadvantages of existing technology: [0005] 1. The controller and the motor are integrated, and the space utilization rate is relatively low; [0006] 2. The controller is integrated with the motor, which is large in size, requires high installa...
