Example Embodiment

[0019] The present invention will be further described below in conjunction with the accompanying drawings:

[0020] like figure 1 , figure 2 The shown drive motor for an electric vehicle includes a base 1 and front and rear end covers 2 and 3 matched with the base 1. The cooling circulation system and the water cooling circulation system circulating between the base 1, the front end cover 2 and the rear end cover 3.

[0021] Further, a stator 11 and a rotor 12 are arranged inside the machine base 1, and the air-cooled circulation system includes a first ventilation hole 111 arranged on the stator 11 and a second ventilation hole 121 arranged on the rotor 12. The first ventilation hole 121 An air duct for circulating hot air is formed between the hole 111 and the second ventilation hole 121 .

[0022] Further, the cross section of the machine base 1 is square, and the front end cover 2 and the rear end cover 3 are also square. The groove, the rear groove arranged on the r...

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...
