Description

Technical Field

[0001] The utility model relates to the technical field of motor stator structures, in particular to a motor stator structure with high-efficiency heat dissipation. Background Art

[0002] The motor stator is a component mainly composed of a casing, a stator core and a stator winding. It has the function of converting electrical energy into electromagnetic energy. During the energy conversion process, part of the electrical energy will be converted into heat energy and consumed in the stator core and the stator winding. During the heat conduction process, part of the heat generated by the stator winding is conducted to the casing through the stator core and is dissipated away by the casing. Another part of the heat is first conducted to the air through the end of the stator winding, and then conducted to the casing through the air, and then is dissipated away by the casing. Due to the low thermal conductivity of air, heat dissipation of the stator core has always been a weak link in the motor.

[0003] The existing stator core for motor with high efficiency heat dissipation (disclosed in: CN216290380U) has at least the following disadvantages:

[0004] When in use, cooling water is injected into the heat dissipation water outlet through the water inlet pipe, and then the nuts of the water inlet pipe and the water outlet pipe are tightened. The water pump is started through an external terminal computer or mobile phone to circulate the cooling water to dissipate heat for the device. However, during the circulation of the cooling water, the temperature will gradually increase due to the absorption of heat. At this time, the cooling water may gradually lose the heat dissipation effect due to the high temperature. Moreover, when replacing the hot cooling water with cooling water with a lower temperature, it is necessary to manually loosen the nuts of the water inlet pipe and the water outlet pipe, and then add cold water to the inside of the water inlet pipe. This is rather troublesome and makes it less practical. Therefore, a motor stator structure with efficient heat dissipation is urgently needed to solve the above problems. Utility Model Content
