Motor with two-way type air cooling structure

Abstract

The invention discloses a motor with a two-way type air cooling structure. The motor comprises a motor body and a driving control box fixed on the motor body, wherein the motor body comprises a base, a hood casing arranged at the rear part of the base and a fan arranged in the hood casing; a plurality of box body radiating ribs are arranged on the surface of one side, close to the motor body, of the control box, and projections of the box body radiating ribs in the radial direction of the motor body are positioned in the outer edge range of the hood casing. According to the motor disclosed by the invention, heat generated in the control box is conducted through the box body radiating ribs; the box body radiating ribs are arranged on one side, close to the motor body, of the control box, so that a distance between two heating sources can be ensured, and the situation that the operating condition of the motor is affected due to heat accumulation at the contact position between the motor body and the control box is avoided; an original one-way air cooling structure in which air blown by the fan only flows in the direction of machine body radiating ribs is transformed into the two-way air cooling structure in which the air path simultaneously flows through the machine body radiating ribs and the box body radiating ribs, and the motor is simple to transform.

Description

【Technical field】 [0001] The invention relates to the technical field of motor manufacturing, in particular to a motor with a two-way air-cooled structure. 【Background technique】 [0002] A motor (also known as an electric motor, motor, etc.) is a device that uses electromagnetic effects to convert electrical energy into mechanical energy. Its working principle is to use the law that the energized coil will be stressed in the magnetic field to make the rotor rotate. During work, part of the electric energy in the motor will be lost and exist in the form of heat energy. The accumulation of heat energy in the motor is harmful, so a lot of heat dissipation ribs are usually installed on the outside of the motor, and the motor will have its own fan to speed up the heat dissipation through the heat dissipation ribs. The air flow rate is so that the heat conducted to the heat dissipation ribs is taken away by the air as soon as possible, so that the motor can be maintained at a nor...

Problems solved by technology

Since the control device contains a circuit, it will also become a heat source, and the heat of the control device will also affect the overall performance. However, usually the control device shell is only a control box with a simple shape, and there is no special setting heat dissipation device, so the aging of the control device will also become an obstacle restricting the function of the component
