Abstract

The utility model provides a YCP 2 series three-phase asynchronous motor which is composed of a stator and a rotor. A stator iron core and a rotor iron core are formed by overlapping and pressing a stator stamping sheet and a rotor stamping sheet. The utility model is characterized in that during overlapping and pressing, the rotor stamping sheet is inclined at a certain angle, a corresponding slot slope which is matched with the number of slots of the stator and the rotor is formed, and the diameters of different iron cores are overlapped and pressed according to the sizes of different oblique slots. In the utility model, the electromagnetic noise of a motor is largely eliminated by changing the slot slope of the rotor iron core after optimized stator and rotor slots are matched under the conditions that other performance indexes are not changed, and the material cost is not increased.

Description

YCP 2The series threephase asynchronous

The utility model relates to dynamo-electric field, particularly a kind of threephase asynchronous.

The domestic Y series threephase asynchronous that generally uses at present is the unified design in the whole nation in 1980, do not do any unified improvement over 20 years always, because epoch limitation, the noise of this serial motors is higher, there is not breakthrough theoretical direction with regard to how eliminating the electromagnetic noise aspect, not saturating to the Reeb analysis, aspect the cooperation of rotor groove, choosing of key elements such as the slot slope of rotor is by empirical data with reference to the result who before has morely.Thereby the harmful effect that the electromagnetic noise that causes motor brings to surrounding environment fails over 20 years fundamentally to be resolved always.

The purpose of this utility model is to provide a kind of YCP ₂The series threephase asynchronous, this motor has been broken through limitation in the past on the stator and rotor groove cooperates, eliminate one, two effectively, third-class low order Reeb, and by adopting the rotor gradient that adapts with it to eliminate the synchronous additional torque that to bring thus, keep other performance index of motor constant thereby be implemented in, under the prerequisite that material cost does not increase, reduce or eliminate the electromagnetic noise of motor significantly.

The purpose of this utility model is achieved by the following scheme: be made of stator, rotor, wherein the stator and rotor iron core is overrided to form by the stator and rotor punching, rotor punching skew angle once when laminating wherein forms and cooperates the slot slope that adapts with stator and rotor groove number.

The utility model when the stator piece external diameter be φ 254.8mm, when internal diameter is φ 159mm, stator and rotor groove number is respectively 48 and 40, its rotor gradient is 13.1 ± 1.1mm.

The utility model when the stator piece external diameter be φ 288mm, when internal diameter is φ 178mm, stator and rotor groove number is respectively 48 and 40, its rotor gradient is 14.6 ± 1.1mm.

The utility model when the stator piece external diameter be φ 327mm, when internal diameter is φ 210mm, stator and rotor groove number is respectively 48 and 40, its rotor gradient is 17.2 ± 1.1mm.

The utility model when the stator piece external diameter be φ 368mm, when internal diameter is φ 245mm, stator and rotor groove number is respectively 48 and 40, its rotor gradient is 20.1 ± 1.1mm.

The utility model when the stator piece external diameter be φ 400mm, when internal diameter is φ 260mm, stator and rotor groove number is respectively 48 and 40, its rotor gradient is 21.3 ± 1.1mm.

Compare with existing Y series threephase asynchronous, it is that its slot slope is then come out through the Reeb analytical derivation through preferred that the groove that the utility model adopts cooperates, and this collocation has reached the optimum efficiency of eliminating electromagnetic noise.Because of the core portion of stator and rotor is exactly the magnetic conduction part of motor, motor properties is played crucial effects, its shape size, fresh water (FW) are on average determining noise, vibration, temperature rise and the various energy index of motor.Therefore, the utility model has adopted special stator and rotor groove to cooperate, and has weakened harmonic wave, so significantly eliminated electromagnetic noise.Adopted special groove bevel very little simultaneously, thereby not only eliminated the harm that because of electromagnetic noise the person is brought for a long time effectively, also efficiently solve simultaneously the jitter phenomenon when eliminating the electric motor starting that noise causes, fundamentally solved and failed the technical barrier of breaking through over 20 years always.
