An integrated motor electrical control system

Abstract

The invention discloses an integrated motor control system, which belongs to the field of motor control systems. The integrated motor control system includes a motor body, a control box, a cooling shell, a tube bundle shell, and the inner wall of the cooling shell and the motor body. A water-cooling cavity is formed between the shells, and an air-cooling cavity is formed between the outer wall of the cooling shell and the inner wall of the tube bundle shell. The tube bundle shell includes several cooling water pipes uniformly distributed along the outer circumference of the cooling shell, and several cooling water pipes pass through the water pump It communicates with the water-cooled cavity, and the rotating shaft of the motor body is provided with an air-cooled impeller for supplying air to the air-cooled cavity. The integrated motor electric control system disclosed in the present invention combines air cooling and water cooling to dissipate heat, and the heat dissipation effect is remarkable, and the air cooling can simultaneously cool down the cooling liquid that has been heated up by the motor, and the cooling liquid can be circulated to cool the motor, and the integration degree is high. It is more energy-saving and environmentally friendly, ensuring that the integrated motor can work stably and normally even under long-term and high-speed operation.

Description

technical field [0001] The invention relates to the field of motor control systems, in particular to an integrated motor electrical control system. Background technique [0002] The integrated motor control system refers to the integration of the motor control component and the motor. Both the motor and the motor control component will generate a lot of heat during the working process. When the two are integrated, it is easy to cause damage to the motor control component. And with the development needs of various fields, the motor is gradually tending to high power density and high speed, which makes the heat generation of the integrated motor more serious, especially when used in a relatively high temperature environment, due to the lack of timely heat dissipation and poor heat dissipation effect, This causes the temperature of the motor to rise, and the control components are prone to abnormal operation, which seriously affects the life and reliability of the product.

[0002] The integrated motor control system refers to the integration of the motor control component and the motor. Both the motor and the motor control component will generate a lot of heat during the working process. The integration of the two may easily cause damage to the motor control component.

And with the development needs of various fields, the motor is gradually tending to high power density and high speed, which makes the heat generation of the integrated motor more serious, especially when used in a relatively high temperature environment, due to the lack of timely heat dissipation and poor heat dissipation effect, The motor temperature rises, and the control components are prone to abnormal operation, which seriously affects the life and reliability of the product

[0003] Existing motor heat dissipation methods usually cool down the motor through water cooling or air cooling, but the water cooling method will cause the temperature of the cooling water to rise rapidly after passing through the motor, and the motor needs to run for a long time, so it needs to continuously input cold water. The waste is serious, and when the water supply is connected to the water tank, it takes up a lot of space due to the large amount of water stored, and it is difficult to achieve circulating cooling after the cooling water passes through the motor and heats up

The air-cooled method has poor cooling effect. When the motor is running at high speed and for a long time, it is easy to burn the motor due to poor heat dissipation.
