Description

Technical Field

[0001] The utility model relates to a motor stator with high heat dissipation efficiency, belonging to the technical field of motor stators. Background Art

[0002] The motor stator is an important component of motors such as generators and starters. The stator is an important part of the electric motor. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field, and the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate (output) current.

[0003] According to the announcement number CN218124409U, a motor stator punching sheet and a motor stator heat dissipation structure are disclosed. The motor stator punching sheet includes a stator punching sheet monomer. The inner surface of the stator punching sheet monomer is provided with winding grooves at equal angles. The surface of the stator punching sheet monomer is provided with multiple ventilation frames. The surface of the stator punching sheet monomer is provided with water cooling pipe installation grooves at equal angles. The utility model relates to the field of motor technology. The motor stator punching sheet achieves the goal of setting winding grooves on the inner surface of the stator punching sheet monomer to facilitate winding of the coil, and setting ventilation frames on the surface of the stator punching sheet monomer to facilitate overall ventilation and improve overall heat dissipation efficiency. When the stator punching sheet monomers are stacked into a stator, a water-cooling pipe can be installed in the water-cooling pipe installation groove to further improve the heat dissipation efficiency of the motor stator. The clamping blocks on both sides of the spring sheet are clamped with the clamping groove, so that the extrusion frame can extrude and fix the water-cooling pipe, improve the fixing stability of the water-cooling pipe, and meet the purpose of use requirements. When the above device fixes the water-cooling pipe, workers are required to install several spring sheets, which makes the installation and removal of the water-cooling pipe inconvenient, thereby making the practicability of the device low.
