Example Embodiment

[0032] The technical solutions of the present invention will be described in detail below through embodiments with reference to the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention.

[0033] The term "and / or" in this article is just an association relationship describing associated objects, which means that there may be three relationships, for example, A and / or B, which can mean: A exists alone, B exists alone, and A and B exist simultaneously. In the three cases of B, the term " / and" in this article is to describe another associated object relationship, which means that there can be two relationships, for example, A / and B, which can mean: there is A alone, and there are two cases of A and B alone , In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

Abstract

The invention discloses a high-reliability integrated motor. The motor comprises: a driving heat dissipation part, which comprises a motor housing, a motor end cover and a rotor, wherein the motor end cover is disposed on the motor housing, and the rotor is disposed on the motor end cover; a motor control member; and a forced air cooling part, which comprises an air speed increasing part, an air speed adjusting part and a forced air cooling source, wherein the air speed increasing part and the air speed adjusting part are both arranged on the motor housing, and the forced air cooling source is arranged on the rotor. According to the invention, after air flow generated by a forced air cooling source is conveyed to the air speed increasing piece, a spraying speed in the air speed increasing piece is increased through the air speed adjusting piece, so the air pressure in the air speed increasing piece is reduced, and a large amount of external air flows into the air flow to improve cooling efficiency. The high-reliability integrated motor is simple in structure, novel in design thought, compact in structure and high in cooling efficiency, a cooling air volume can be adjusted according to a heating value, and the motor and a controller can be cooled at the same time.

Description

technical field [0001] The invention relates to the technical field of electric motors, and more specifically, the present invention relates to a high-reliability integrated electric 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 insulation breakdown will occur and the motor will burn out. Existing heat dissipation methods for motors all use the rotating fan that comes with the motor, but the heat dissipation effect is not good, and the heat dissipation requirements of high-power motors are required. The motor and the motor controller are currently independently designed. When the power system layout of the motor and t...
