Embodiment Construction
[0013] Preferred embodiments of the present invention are described in detail as follows in conjunction with accompanying drawings:
[0014] see Figure 1~Figure 4 , a motor stator for improving motor performance, comprising a stator inner ring 1 and a stator outer ring 2, the stator inner ring 1 and the stator outer ring 2 are all made of silicon steel sheets of the same specification, the stator inner ring The ring 1 is used to inlay the stator winding and reduce the cogging torque. The stator outer ring 2 is used to install the stator inner ring 1 to improve the strength of the motor stator and facilitate assembly with the casing. The stator inner ring 1 includes winding grooves 3, winding teeth 4, V-shaped grooves 5, and raised ridges 6. The winding grooves 3 and winding teeth 4 are evenly spaced from each other, and the raised ridges 6 are located at the At the top of the tooth 4, a V-shaped groove 5 is processed on the inner circular surface of the stator inner ring 1, ...

The invention relates to a motor stator for improving the motor performance. The motor stator comprises a stator inner ring and a stator outer ring, wherein the stator inner ring is used for winding a motor winding, the stator outer ring is used for fixing the stator inner ring, and the stator inner ring and the stator outer ring together form the motor stator; the stator inner ring comprises winding slots, winding teeth, V-shaped slots and convex ridges; the winding slots and the winding teeth are mutually spaced and uniformly arranged; the convex ridges are positioned at the top ends of the winding teeth; the V-shaped slots are formed in the inner circle surface of the stator inner ring and stay in the same radial direction as the winding teeth; the winding slot is used for embedding the stator winding; the V-shaped slot is used for reducing the cogging torque of the motor so as to improve the motor performance; and grooves are formed in the inner circle of the stator outer ring and are in interference fit with the convex ridges on the stator inner ring to facilitate the mounting of the stator inner ring. With a simple structure and high strength, the motor stator provided by the invention can improve the air-gas flux density of a permanent magnet synchronous motor and reduce the cogging torque of the permanent magnet synchronous motor so as to improve the motor performance.
Description
technical field [0001] The invention relates to the field of motor design, in particular to a motor stator for improving motor performance. [0002] technical background [0003] Whether in life or industrial production, permanent magnet synchronous motors play an irreplaceable role. The stator is an important component of the motor. The existing motor stator is made of a whole silicon steel sheet, and is wound internally. It is inevitable to design a wire-embedded notch on the inner surface of the stator. This design It will lead to the generation of cogging torque and reduce the performance of the motor. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a motor stator for improving the performance of the motor, so as to reduce the cogging torque of the permanent magnet synchronous motor, improve the air gap flux density, and improve the performance of the motor. [0005] In order to realize...
