Description
Technical field
The utility model relates to a kind of used for electric vehicle triphase AC variable frequency speed-regulating asynchronous motor stator iron-core lamination.
Background technology
For reaching environmental protection, energy-conservation, the purpose that reduces discharging, it is extremely urgent that exploitation accounts for the high efficiency motor of whole industrial electric weight 2/3, and Inverter Application becomes a reality electric motor energy-saving technique.Stator iron-core lamination is the vitals of three-phase alternating current variable-frequency motor, but existing stator punching punching out direction error rate height causes inefficiency.
The utility model content
The purpose of this utility model provides a kind of increasing work efficiency, and can guarantee the used for electric vehicle three-phase alternating current variable-frequency motor stator iron-core lamination of each stator punching punching out direction unanimity.
For achieving the above object, the utility model adopts following technical scheme: a kind of three-phase alternating current variable-frequency motor stator iron-core lamination, the stator core stamping sheet body that comprises annular, the edge, outer ring of stator core stamping sheet body is laid with the cramp groove, the inner ring edge of stator core stamping sheet body is laid with the stator punching groove, one of them cramp groove is labeled slots, and the groove bottom of labeled slots also is provided with a groove.
Described groove is square groove.
The semi-closed port formula groove that described stator punching groove shrinks for the notch place.
Described stator core stamping sheet body thickness is 0.5mm or 0.35mm, and the stator core stamping sheet body is the cold rolled silicon steel stamping parts.
Three-phase alternating current variable-frequency motor stator iron-core lamination described in the utility model, have following beneficial effect: stator punching body cylindrical is provided with labeled slots and a plurality of cramp groove, the cramp groove is for effectively a plurality of stator punchings being laminated into stator core and preventing distortion unshakable in one's determination, what of cramp groove determine by the size of punching external diameter and evenly distribute along circumference that labeled slots guarantee each stator punching punching out direction unanimity.According to the motor performance requirement, under the principle of selecting for use reasonable groove to cooperate, stator punching groove flute profile is the semi-closed port peariform slot, is conducive to reduce pulsation loss in surface loss unshakable in one's determination and the tooth, and the stator punching flute profile adopts the parallel teeth design and optimizes, guaranteed favorable manufacturability, be convenient to manually roll off the production line, can control the end size of radial dimension and the stator winding of stator winding effectively, improved the utilance of material, reduce the consumption of winding copper cash, satisfied the designing requirement of efficient energy-saving.Stator iron-core lamination be by thickness be 0.5 or the punching out of 0.35mm cold-reduced silicon sheet form.The punching material has good magnetic property, has lower magnetic hysteresis loss and eddy current loss under certain frequency and magnetic flux density, and the silicon steel plate thickness is even, smooth surface, smooth.Through verification experimental verification, by its triphase AC variable frequency speed-regulating asynchronous motor that constitutes, the cost of raw material reduces by 15%, compares with the same size motor, and efficient improves 1～5%.By the triphase AC variable frequency speed-regulating asynchronous motor that this stator punching constitutes, rated frequency is 80～200Hz; Show through operation result repeatedly, under 0～400Hz, the converter power supply power supply, its runnability is good and safe and reliable.
