Drive motor used for electric vehicle

Abstract

The invention relates to a drive motor used for an electric vehicle. The drive motor comprises an engine base, a front end cover and a rear end cover, wherein the front end cover and the rear end cover are matched with the engine base. The drive motor further comprises an air cooling circulating system and a water cooling circulating system, wherein the air cooling circulating system and the water cooling circulating system are arranged inside the engine base, and the water cooling circulating system circulates between the engine base, the front end cover and the rear end cover. According to the technical scheme, the air cooling circulating system and the water cooling circulating system which circulates between the engine base, the front end cover and the rear end cover are arranged inside the engine base at the same time, the two circulating systems can be used simultaneously and effectively for dissipating heat inside the engine base, the front end cover and the rear end cover, therefore, the heat dissipation performance is good, and the service life of the drive motor is prolonged; meanwhile, the drive motor is compact in structure and small in size, thereby occupying a small space.

Description

technical field [0001] The invention relates to a drive motor, in particular to a drive motor for an electric vehicle. Background technique [0002] With the rapid development of my country's economy, many large cities are densely populated with cars and traffic is congested, and cars need to start and stop frequently. For traditional internal combustion engine vehicles, this operating mode will lead to a series of problems such as poor emissions, high noise, and high fuel consumption. . my country is a big energy-consuming country, and domestic energy reserves are relatively scarce, and a large amount of energy needs to be imported. Therefore, the development of new energy electric vehicles with low emissions and low fuel consumption has become an urgent task for my country's automobile industry today. With the comprehensive development of new energy vehicles, various requirements are constantly improving. As an important part of the whole vehicle, the quality of the drive...

Problems solved by technology

As an important part of the vehicle, the quality of the drive motor is particularly important. The important factor affecting the quality of the drive motor is the heat dissipation performance. The heat dissipation and cooling system of the traditional car drive motor is arranged on the casing in a spiral shape, and its heat dissipation effect is not good. Well, the service life of the driving motor is reduced. At the same time, due to its poor heat dissipation performance, the volume of the driving motor is relatively large and the speed is relatively low. These defects make it difficult for the traditional driving motor to be widely used in new energy vehicles. of various models
