Problems solved by technology

This method of setting the motor and the controller separately has the advantages of self-contained system and less mutual interference, but it also has relatively large defects: 1. The electric vehicle is a mobile sports tool, and its effective space is very precious. Yes, for small cars, the situation is even more so. The driving motor and the control four are set separately, which inevitably increases the occupied space, which is unfavorable to the overall design of the electric vehicle; 2. Increases the ineffective weight, such as the control 3. Increased energy consumption, not only the cooling fan needs to consume electric energy, the controller and the motor are placed separately, which increases the loss of the connecting line

Embodiment Construction

[0015] The drive motor 1 is water-cooled, and an octagonal or rectangular water jacket 9 is set outside the motor casing 8. On one surface of the water jacket, a power tube IPM or IG BT 2 is installed, and a control circuit board is arranged on the other surface 3. Between the water jacket and the motor casing is the cooling water flow channel. The joints of the water inlet and outlet pipes 5 and 4 are arranged at the end of the motor. The cooling water can flow in the water channel around the motor casing through the water inlet and outlet pipes, and the motor and power The heat generated during the working process of the tube is taken away. Also just no longer need to arrange radiator and cooling fan. The water jacket is also provided with a temperature controller 11, which can adopt gravity circulation and forced circulation respectively according to the water temperature, so as to control the temperature of the motor and the power tube through the flow of cooling water.

Abstract

An electromechanically integrated power unit for electric car features that a water cooled motor is used and the power transistors IPM (or IGBT) and control circuit are arranged on the water jacket of motor. Its advantages are light weight, small size, simple structure and low energy consumption.

Description

technical field [0001] The invention relates to the improvement and improvement of the electric vehicle power device Background technique [0002] As a non-polluting, green and environment-friendly vehicle, electric vehicles are deeply concerned by people from all walks of life, and many countries in the world are sparing no effort to develop them. As far as the current problems are concerned, the key to electric vehicles lies in the energy structure. The existing battery technology is not enough to make the stored electric energy of the battery comparable to the chemical energy of the car, and the difference is two orders of magnitude. This makes electric vehicles a worldwide problem and difficult to enter into commercial operation. How to reduce the energy consumption of electric vehicles has become the key to the research and development of electric vehicles. [0003] In the research and development of electric vehicles, the driving motor and the control device are gene...
