Abstract
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
The present invention relates to design of electrical motor field, more particularly, to a kind of motor stator for improving motor performance.
Technical background
No matter in life or in commercial production, permagnetic synchronous motor suffers from irreplaceable effect.Stator is electricity
The important building block of machine, existing motor stator is to be formed by a whole silicon steel plate packing, and is the side with internal threads
Formula, inevitably needs to be designed with rule notch in stator inner surface, and this design can lead to the generation of cogging torque, reduces electricity
The performance of machine.
Content of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of motor stator for improving motor performance,
To reduce the cogging torque of permagnetic synchronous motor, improve air gap flux density, improve motor performance.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of motor stator for improving motor performance, including stator inner ring, stator outer ring, described stator inner ring is used for coiling
Machine winding, described stator outer ring is used for fixedly mounting stator inner ring, and the two is collectively forming motor stator;Described stator inner ring bag
Include winding slot, coiling tooth, V-shaped groove, convex ridge, described winding slot and coiling tooth are spaced evenly distributed, described convex ridge be located at around
The top of line tooth, the inner headed face of described stator inner ring is machined with V-shaped groove, and this V-shaped groove and coiling tooth are in same radial direction
On direction, described winding slot is used for inlaying stator winding;V-shaped groove is used for reducing the cogging torque of motor, to improve motor performance;
The inner circle processing of described stator outer ring is fluted, is connected to install stator inner ring with the convex ridge interference on stator inner ring.
Compared with prior art, the present invention has the advantage that:
Because this motor stator can be so the inner circle of stator inner ring is closing, uncommon from the outside coiling of stator inner ring
The stator rabbet of rule is used on stator inner circle.The design of V-shaped groove and closing inner ring can be used for reducing the tooth of permagnetic synchronous motor
Groove torque, improves air gap flux density, improves motor performance.
