Description

Technical Field

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

[0002] The electronic stator, usually referred to as the stator, is the stationary part of the motor, mainly composed of an iron core, windings (or coils) and other related components. Its main function is to generate a magnetic field, which interacts with the magnetic field generated by the electronic rotor to drive the motor to rotate. When power is passed into the stator winding, current begins to flow in the winding, generating a magnetic field. The direction and size of this magnetic field depend on the direction and size of the current.

[0003] When installing magnetic tiles inside a motor housing, the method of directly bonding the magnetic tiles to the inner wall of the motor housing is generally adopted. Although this bonding method is simple and direct, after long-term use, due to factors such as the holding force of the adhesive, the bonding between the magnetic tiles and the inner wall of the motor housing may be loose. This loose bonding may cause the magnetic tiles to loosen or fall off. For this purpose, a motor stator structure is proposed. Utility Model Content

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The utility model provides a motor stator structure. During bonding, glue is evenly applied to a number of glue injection holes, the glue enters the inner cavity of the glue injection cylinder and the molding groove, and then the magnetic tile is placed between two limit seats, so that the glue bonds and fixes the magnetic tile and the stator shell. After the glue is solidified and formed in the inner cavity of the glue injection cylinder and the molding groove, the solidified glue is embedded in the stator shell in the shape of a rivet.
