Abstract
The utility model provides the technical improvement of a salient-pole single-phase motor, which is composed of a main winding of a stator, a secondary winding of the stator, a stator core and a rotor. The utility model is characterized in that the stator core is provided with two pairs of convex magnetic poles, wherein, one pair is the main winding. The other pair is the secondary winding. The secondary winding is connected with a power supply through a phase shifting element. The utility model not only reserves the advantages of an original motor, but also has the advantages of raised starting torque and doubled raised efficiency. The utility model can be suitable for using on many occasions.
Description
The utility model relates to a kind of technological improvement of salient pole type single-phase motor.
Existing salient pole type single-phase motor, formed by stator main winding, stator auxiliary winding, stator core and rotor, in the salient pole type stator core, corresponding main winding is for concentrating winding, is with the very little short circuit copper ring of resistance as the stator auxiliary winding in the sub-fraction (about 1/3 width of pole shoe) of pole shoe, and the electric motor structure of this structure is simple, noise is low, but, be used for the less demanding occasion of starting torque because starting performance and runnability are all relatively poor, thereby only make very low capacity.
The purpose of this utility model is the shortcoming at above-mentioned motor, and a kind of technological improvement is provided, and has kept all advantages of original motor, has improved the starting torque of motor again, and overload capability significantly improves, and can adapt to more conditions and use.
The utility model is achieved in that the magnetic pole that two pairs of projectioies are arranged in stator core, wherein a pair of as the stator main winding, another is to as the stator auxiliary winding, stator main winding and stator auxiliary winding axis about 90 ° of electrical degrees of spatially being separated by, the magnetic pole of stator auxiliary winding be stator main winding magnetic pole 1/3rd to identical, the stator auxiliary winding inserts power supply by phase shifting component.
Figure is further described the utility model below in conjunction with example structure.
Fig. 1 is a structure principle chart of the present utility model.
Among the figure, the 1st, stator main winding, the 2nd, stator auxiliary winding, the 3rd, stator core, the 4th, rotor.
The magnetic pole that two pairs of projectioies are arranged in stator core (3), wherein a pair of as stator main winding (1), another is to as stator auxiliary winding (2), main winding and auxiliary winding axis about 90 ° of electrical degrees of being separated by in the space, stator auxiliary winding (2) is according to performance requirement, its magnetic pole be stator main winding magnetic pole 1/3rd to identical, and insert power supply by phase shifting component.The utility model has kept the advantage of shaded pole motor, has improved starting torque again, and efficient significantly improves, and can be fit to more conditions and use.
