Description

Technical Field

[0001] The utility model relates to the technical field of AC motors, in particular to an AC motor for an engineering lifting vehicle. Background Art

[0002] Currently, engineering lifts generally use AC motors for power input. During the use of AC motors, the rotor needs to rotate quickly, and a large amount of heat will be generated during the rotation of the rotor. The increase in heat will increase the temperature of the coil in the rotor. When the rotor works in a high temperature environment for a long time, the temperature of the motor body will also increase, causing the motor to consume more energy, shorten its service life, and may burn out. In order to reduce the temperature of the motor, it is necessary to cool the motor to ensure the normal use of the motor.

[0003] At present, when cooling the motor, most of them adopt air cooling or water cooling. When adopting air cooling, fan blades can be directly installed on the motor. However, the method of using fan blades to dissipate heat can only be used when the motor is working for a short time. When the motor is used for a long time, the temperature on the motor body rises, and the effect of air cooling will become worse, which will affect the cooling effect of air cooling on the motor. When using water cooling, it is necessary to connect external electrical appliances. As the cooling progresses, the cooling water temperature will increase, thereby gradually reducing the cooling effect. Utility Model Content
