Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of winding type iron core, in particular to a winding type iron core for motor. BACKGROUND

[0002] The winding type iron core for motor is mainly responsible for the formation of magnetic circuit and the guidance of magnetic flux. After the winding (wire coil) is electrified, the magnetic flow forms a magnetic field between the coil and the iron core, thereby driving the rotation of the motor. The iron core provides a low magnetic resistance path to concentrate the magnetic flux, improve the magnetic field strength and efficiency. The iron core provides stable mechanical support and fixed position for the winding, ensuring the safety and firmness of the winding, and can convert electrical energy into mechanical energy (rotation) to realize the basic function of the motor. Moreover, reasonable design of the iron core can reduce magnetic hysteresis loss and eddy current loss, and improve efficiency.

The inner end of the yoke portion is provided with a yoke portion anti-wrinkle groove and an injection molding positioning groove. The injection molding positioning groove is arranged at the tooth root of the tooth portion. The yoke portion anti-wrinkle groove is arranged at the intermediate position between the two adjacent tooth portions. A plurality of buckling points are integrally arranged on the tooth portion. A plurality of buckle grooves matched with the buckling points are arranged on the end face of the other end of the tooth portion relative to the buckling points. The above technical solution has reasonable structure design, simple structure, and is not easy to wrinkle at the inner end of the yoke portion, not easy to tear at the outer end of the yoke portion, not easy to warp and deform at the tooth portion, small gap between laminations, and good practicability.

[0004] At present, the existing winding type iron core of motor lacks special positioning mechanism inside or outside during installation and use, which means that during assembly, additional positioning frame or auxiliary means must be relied on to assist in fixing the position of the iron core.
