Abstract
The utility model relates to a material-saving single-phase AC asynchronous motor with high performance, which is mainly composed of pieces, such as a machine shell, an end cover, a stator core, a winding of the stator core, a rotor core, the winding of the rotor core, a rotating shaft, a fan, etc. A stator groove and stator teeth are punched at the inner edge of a punching sheet of the stator core. The dimensions of adjacent stator teeth and the stator groove of the utility model are different from each other. A groove shape can be a round bottom groove and can be also a flat bottom groove. Because the motor is made of the punching sheet of the stator, the utility model has the advantages of raw material saving, low cost and favorable performance. The utility model is suitable for making a new-style electric machine or improving the existing electric machine.

The utility model belongs to a kind of single phase alternating current (A.C.) asynchronous motor, particularly a kind of material-saving, well behaved single phase alternating current (A.C.) asynchronous motor.
At present, being connected on the monopole asynchronous motor that exchanges single phase poaer supply is most widely used a kind of driving electrical micro-machine.But it is many that this motor manufacturing expends raw material, the cost height.As producing according to original structure manufacturing, be difficult to reduce cost, improve performance.
The purpose of this utility model is to provide a kind of saving raw material, reduces cost, and well behaved single phase alternating current (A.C.) asynchronous motor.
Technical solution of the present utility model is as follows:
The structure of material-saving, well behaved single phase alternating current (A.C.) asynchronous motor is, installing end cap (2) and (3) respectively at the two ends of casing (1), adorning the stator core of forming by stator core stamping sheet (4) (5) in the casing, inlaying winding (6) in the groove of stator core, adorning the rotor core of forming by rotor core punching (7) (8) at the center of stator core, inlaying winding (9) in the groove of rotor core, install rotating shaft (10) on the rotor core, in rotating shaft, adorning fan (11) and centrifugal switch (12).The structure of forming the stator core stamping sheet of stator core is, dashing at the interior circle of stator core stamping sheet has stator slot and stator tooth, the stator slot that it is adjacent and the size of stator tooth are different, the ratio range of maximum groove width and minimum slot width is in 1~2.5, the ratio range that vat is high and minigroove is high is in 1~2, the ratio range of maximum slot opening and minimum slot opening is in 1~1.5, the ratio range of the maximum facewidth and the minimum facewidth is in 1~2.5, maximum tooth apart from the ratio range of minimum tooth distance in 1~2.5.
Flute profile can be a round bottomed vessel, can also be flat-bottom slot.
The utility model compared with prior art has following advantage:
1, saves raw material.The stator core that utilizes this technology to make motor can make core length shorten, thus the save silicon steel disc, generally speaking can save silicon steel disc 6.6%~20%.
2, reduce cost.Owing to saved raw material, so can reduce the cost of motor, every motor can increase profit 5~30%.
3, improve motor performance.Utilize this technology to make the stator core of motor, cooperate other technologies to reduce and pass the preface rotating magnetic field in the air gap, thereby improve motor properties.Two breakdown torques of putting capacitor motor of producing at present are often on the low side, do not increasing under the raw-material situation, improve quite difficulty of its torque, adopt the present technique designed motor, not only do not increase silicon steel sheet, also can under the situation of save silicon steel disc, improve the breakdown torque of motor.
4, applied widely.This motor is applicable to single-phase resistance starting asynchronous motor, single-phase capacitance starting asynchronous motor, single-phase capacitor operation motor, single-phase capacitance starting and running asynchronous motor (two capacitance asynchronous motor of putting) etc.Also can be used for improvement to existing monopole asynchronous motor.
5, part can generally exchange, and the production inheritance is good.For the series substantially of existing monopole asynchronous motor, same support, can generally exchange with the rotor punching of number of poles, be easy to produce.The existing producer that produces monopole asynchronous motor adopts present technique, can inherit original motor structure and production technology and production management.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of the utility model monopole asynchronous motor;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is that the utility model monopole asynchronous motor stator slot is the stator core stamping sheet structural representation of round bottomed vessel;
