Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor stator core structure. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. It is divided into motors and generators. It uses an energized coil (that is, a stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel cage closed aluminum frame) to form a magnetic electromotive force rotating torque. The stator core is an important part of the motor's magnetic circuit. It, together with the rotor core and the air gap between the stator and the rotor, forms a complete magnetic circuit for the motor. In an asynchronous motor, the magnetic flux in the stator core is alternating, resulting in core loss. Core loss consists of two parts: hysteresis loss and eddy current loss.

[0003] However, the existing motor cooling method mainly uses an oil spray pipe arranged near the top of the motor stator and the end of the winding and designs an oil spray hole on the oil spray pipe. The cooling medium is sprayed from the oil spray hole to the outer cylindrical surface of the stator core and the end of the winding, resulting in poor heat dissipation performance of the stator core, increasing the overall motor temperature, and affecting the service life of the motor.

The radiator 2 is a device for discharging the heat generated by the device into the surrounding environment. Its main purpose is to dissipate the heat inside the device to the outside through effective heat conduction and heat convection to maintain the normal operating temperature of the device. When the motor is working, a large amount of heat is generated. This heat is firstly conducted through the surface of the device in contact with the radiator 2. Usually, the radiator 2 uses metal materials with good thermal conductivity (such as aluminum, copper, etc.) to improve the heat conduction efficiency. Once the heat is conducted to the surface of the radiator 2, the heat sink accelerates the heat dissipation by increasing the surface area. The surface design of the radiator 2 usually has many heat dissipation fins to increase the surface area, so as to more effectively exchange heat with the surrounding air. This part is mainly assisted by the heat dissipation fan 3, and a fan or liquid cooling system is used to accelerate the flow of air or coolant, so as to more effectively take away the heat.

[0032] Working principle: When the drive motor 1 is working, the coolant flows from the cooling groove 8 through the second water inlet pipe 10 under the action of the water pump 11, and flows into the cooling channel 13 on the outer cylindrical surface of the stator core body 17. When it flows to the water outlet 16, it flows into the cooling groove 8 through the second water outlet pipe 9. Under the action of the radiator 2 and the cooling fan 3, the heat absorbed from the stator core body 17 is transported to the outside of the drive motor 1. The coolant flows through the outer cylindrical surface of the entire stator core body 17, increasing the flow area of ​​the coolant. The coolant absorbs heat, cools down the stator core, improves the heat dissipation capacity of the stator core, and thereby improves the heat dissipation effect of the drive motor 1.
