A highly reliable integrated motor

Abstract

The invention discloses a high-reliability integrated motor, comprising: a drive heat sink, the drive heat sink includes a motor housing, a motor end cover and a rotor, the motor end cover is arranged on the motor housing, and the rotor is arranged on the motor end cover The motor control part; the forced air cooling part, the forced air cooling part includes the wind speed increasing part, the air speed adjusting part and the forced air cooling source. on the rotor; wherein: after the forced air cooling source delivers the generated air flow to the wind speed increasing member, the injection speed in the wind speed increasing member is increased by the wind speed adjusting member, so as to reduce the air flow in the wind speed increasing member The air pressure causes a large influx of external atmosphere to improve cooling efficiency. The invention has simple structure, novel design idea, compact structure and high cooling efficiency, can adjust the cooling air volume according to the calorific value, and can simultaneously radiate the motor and the controller.

Description

technical field [0001] The present invention relates to the technical field of motors, and more particularly, the present invention relates to a highly reliable integrated motor. Background technique [0002] The core of the power system is the motor and the motor controller. The motor is a device that converts electrical energy into mechanical energy. It is mainly composed of a stator, a rotor, a casing, an end cover and a controller. When the motor is in use, the motor will generate a lot of heat. When the heat reaches a certain level, the motor cannot be used, otherwise the insulation breakdown will occur and the motor will burn out. Existing motor heat dissipation methods all use the rotating fan provided by the motor to fan heat, but the heat dissipation effect is not good, and the heat dissipation of high-power motors is required. The motor and the motor controller are currently independently designed. When the power system layout of the motor and the motor controller...

Problems solved by technology

Although this combination method brings convenience to the modular production of motors and controllers, too many mechanical and electrical interfaces restrict the miniaturization and simplification of the power system, and the current layout space of the power system is limited, making the motor and motor The size of the controller should be as small as possible, and the piping and wiring harness should be designed as short as possible

In addition, due to the separate installation of the motor and the controller, the connection of the motor three-phase line and the low-voltage signal line is relatively long, resulting in high production costs and poor anti-electromagnetic interference ability
