Technical Field
[0001] The utility model relates to the technical field of motor stator heat dissipation, in particular to a motor stator heat dissipation structure and a motor. Background Art
[0002] In the field of motor technology, stator heat dissipation has always been a key issue. With the continuous development of motor technology and the continuous expansion of application fields, the requirements for motor performance are getting higher and higher, especially the heat dissipation performance of the motor. During the operation of the motor, due to the resistance heat generated by the current passing through the wire, as well as the eddy current loss and hysteresis loss generated by the change of the electromagnetic field, etc., the temperature inside the motor will rise. And the stator of the motor, as an important part of the motor, its heat dissipation effect directly affects the overall performance and service life of the motor.
[0003] Traditional motor stator heat dissipation structures mostly adopt natural cooling methods, that is, using natural convection and radiation heat dissipation of air. However, in the case of a large motor power or a harsh operating environment, this method often fails to meet the heat dissipation requirements, resulting in an increase in the motor temperature, which in turn affects the efficiency and reliability of the motor. In addition, some motors also adopt forced cooling methods such as air cooling and water cooling, but these methods often require additional cooling equipment and energy, increasing the complexity and cost of the motor.
[0004] Therefore, researching and developing an efficient, economical and reliable motor stator heat dissipation structure is of great significance for improving motor performance and extending service life.
[0005] For this reason, we propose a motor stator heat dissipation structure and a motor. Content of the Utility Model

Plug holes are evenly distributed along the circumferential direction on the front side of the outer stator core. A heat dissipation rib is slidably inserted into each plug hole. The heat dissipation rib is made of a phase change material.
[0008] Further, heat dissipation holes are evenly distributed along the circumferential direction on the outer wall of the outer stator core.
[0009] Further, the outer stator core is sleeved outside the inner stator core.
[0010] Further, an inner spiral groove is formed in the inner wall of the outer stator core along the circumferential direction.
[0011] Further, an outer spiral groove is formed in the outer wall of the inner stator core along the circumferential direction.
