Description

A motor equipped with a new type of ventilation and heat dissipation structure, and the cooling method is IC23

technical field

The utility model belongs to the technical field of electric motors, in particular to an electric motor equipped with a novel ventilation and heat dissipation structure, and the cooling mode is IC23.

Background technique

An electric motor is a commonly used rotating electrical machine that converts electrical energy into mechanical energy. Machine tools and water pumps need electric motors; electric locomotives and elevators need electric motors; electric fans, refrigerators, washing machines, and even various electric motor toys in family life are inseparable from electric motors; therefore, electric motors have been used in all aspects of modern social life .

During the use of the motor, due to the existence of various losses, the temperature continues to rise. For normal use, cooling is especially important; if it cannot be cooled well, it will affect the service life of the motor. If the heat dissipation capacity of the motor is poor, the temperature of the motor will be too high, which will affect the service life of the motor, cause problems such as crash, and even threaten the life safety of the operator in severe cases.

At present, the heat dissipation of high-speed motors is generally to add heat sinks on the motor shell, and use the heat sinks to dissipate the heat generated by the operation of the motor; at the same time, quite a few manufacturers also install fans to dissipate heat from the motors. For the heat dissipation method using heat sinks, adding several heat sinks to the motor shell will increase the weight of the entire motor, and the consumables will also be relatively large. In the face of the reality that resources are increasingly scarce, it is obviously not advocated by the country. of. As for the heat dissipation method of adding a fan, since the fan will generate a lot of noise during operation, it is not suitable for application in specific environments such as residential areas, elevators and other places; in addition, adding a motor will also increase the structural size of the entire motor .

There are two types of IC23 motor cooling methods: one is a Y series motor with a square box structure, as shown in Figure 1, this structure is equipped with inlet and outlet louvers on both sides of the square casing to cool the motor ; There is also a circular front and rear end cover opening shape, with an external fan and a windshield. Under the action of the external fan, the cooling air enters the motor from the opening hole of the rear cover at the non-shaft extension end, and the heat after heat exchange is transferred from the shaft. Extend the end cap opening hole to discharge.

The cooling effect of the above two motors is very good, but the disadvantage is that the volume of the square structure is relatively large, which is limited by the matching of some equipment; and the circular structure with the opening of the front and rear end caps, because the end coils in the open end caps are easy to The motor is damaged by the influence of foreign debris.
