Motor stator structure and motor with same

Abstract

The motor stator structure comprises a stator iron core and a winding coil arranged on the stator iron core, a thermal expansion cold plate is arranged on the outer side of the end portion of the winding coil, the thermal expansion cold plate is matched with the winding coil, a heat dissipation end cover is arranged on the outer side of the thermal expansion cold plate in a sleeving mode, and the heat dissipation end cover is matched with the thermal expansion cold plate. A winding wire passing groove is formed in the inner wall of the thermal expansion cold plate, and the winding coil is arranged in the winding wire passing groove of the thermal expansion cold plate in a penetrating mode. Heat-conducting male teeth are arranged on the outer wall of the thermal expansion cold plate, and heat-conducting female teeth are arranged on the inner wall of the heat dissipation end ring. By adding the thermal expansion cold plate and the heat dissipation end ring at the end part of the motor stator, the heat dissipation capability and the protection capability of the winding end part of the motor stator are enhanced, and the reliability of the motor is improved. The heat conduction male teeth and the heat conduction female teeth are arranged on the contact surface of the thermal expansion cold plate and the heat dissipation end ring, so that the heat conduction efficiency of the thermal expansion cold plate and the heat dissipation end ring is improved, the heat dissipation capability of the thermal expansion cold plate is further enhanced, and the temperature rise of the motor is reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor stator structure and a motor having the same. Background technique [0002] With the development of permanent magnet synchronous motor technology, small size, high power density and high reliability have become important indicators in motor design. [0003] However, due to the increase in power density of the motor, the iron loss and copper loss per unit volume of the stator increase, and the heat generated during operation is not easy to cool. If a large amount of heat on the motor is not dissipated, the temperature rise of the motor will be too high, which will directly affect the insulation performance of the motor, reduce the service life of the motor, and even cause damage to the motor. [0004] In addition, due to the requirements of the insulation level of the motor and to meet the requirements of various operating environments, it is necessary to protect the ends ...
