Abstract
The utility model relates to a hidden salient pole capacitor motor of a miniature motor for driving. After a yoke ring piece and a salient pole piece are stacked, the yoke ring piece and the salient pole piece are assembled to form a stator of the utility model. The utility model is characterized in that the salient pole piece is a duplex salient pole piece of a smooth inner circle. Pole tips of both contiguous salient poles are orderly connected, and all salient poles become a whole, so that the duplex salient pole piece of a smooth inner circle is formed. The inner edge of the yoke ring where a magnetic pole is arranged is punched a magnetic pole fixing slot. The magnetic pole fixing slot is used for pressing and installing the salient poles. Shapes of roots of the salient poles and sizes of the roots of the salient poles correspond to the shapes of the magnetic pole fixing slot and the sizes of the magnetic pole fixing slot. Concentrated windings which are favorable for wholesale manufacture can be used because of the salience poles. The utility model has the advantage of convenient installation because of the duplex salient pole piece. A concentricity degree for assembling the magnetic pole is raised; a symmetry degree for distributing a magnetic path is raised. Therefore, the utility model has the advantages of both of the salient poles and a non-salient pole structure.
Description
The utility model relates to a kind of driving micro asynchronous motor, particularly a kind of miniature latent salient pole type capacitor motor.
Capacitor motor, that is permanent split capacitor motor, generally be hidden pole type distributed winding stator and cage rotor structure, than salient pole type, the advantage of this stator structure is to help guaranteeing the concentricity of rotor and the symmetry that magnetic pole distributes, especially just more be necessary for the asynchronous machine that has only gas length between very little rotor originally, but the distributed winding rule of hidden pole type is time-consuming, directly influence the raising of this kind motor production efficiency, particularly when the ratio of the core length of stator and internal diameter reaches enough big, often cause the rule difficulty, production efficiency is lower, the repair rate height, consequently cost of goods manufactured rises.
The purpose of this utility model provides a kind of miniature latent salient pole type capacitor motor, and its stator core is a salient pole type, and the pole tip of each adjacent salient pole is connected to each other, and is a kind of capacitor motor that has salient pole and non-salient pole advantage concurrently therefore.
The utility model is so to realize: a kind of latent salient pole type capacitor motor, its stator core is assembled after laminating by yoke ring sheet and salient pole sheet, be characterized in that the salient pole sheet is the compound salient pole sheet that pole tip links to each other successively, smooth, the whole salient pole of interior circle becomes one of two adjacent salient poles, the inner edge of yoke ring sheet dashes at installation magnetic pole place to have and press-fits the corresponding magnetic pole holddown groove of salient pole shape size that use and the salient pole root.
Above-mentioned yoke ring sheet is circular, square or polygon.The root of salient pole and with it the magnetic pole holddown groove of corresponding matching be square or swallow-tail form, two adjacent pole tip places between two adjacent magnetic poles on the geometric center lines have one to cut oblique arc in order to the pole tip of cutting oblique pole tip.
The utility model is the salient pole machine structure, it is main and auxiliary coil that the concentrated winding of production in enormous quantities is suitable in employing, can enhance productivity significantly, and when reaching higher value, the ratio of stator core length and internal diameter do not increase difficulty in the manufacturing yet, thereby help adopting different core lengths to obtain the more products specification according to Electromagnetic Design, further reduce product cost.Because whole magnetic poles of motor fuse and once are washed into, the magnetic pole root is press fit in the magnetic pole holddown groove of yoke ring by mould again, thereby it is each magnetic pole and pole coil is therebetween hidden, not only than original elder generation is integral pole lamination through laminating riveting, put coil and improved operating efficiency greatly with the technology that screw is installed in yoke portion again, the concentricity of magnetic pole installation and the symmetry that magnetic pole distributes have also been improved significantly, thereby guaranteed the harmony that magnetic circuit distributes, helped to improve motor performance.So stator punching of the present utility model has had the advantage of salient pole and non-salient pole structure concurrently.In sum, the stator design of this motor not only helps improving the quality of products, and simple in structure, easily manufactured, and be suitable for and carry out high efficiency production in enormous quantities, causing its manufacturing cost, in addition more cheap than shaded pole motor.Therefore, this functional, low-cost capacitor motor can be widely used in smoke exhaust ventilator, ventilation fan and as the supporting uses of multiple household electrical appliance such as cooling blower of refrigerator, refrigerator-freezer, air-conditioning.
Now be described further with following embodiment and accompanying drawing thereof.
Fig. 1 is a schematic cross section of the present utility model.
Fig. 2 is salient pole punching figure of the present utility model.
Fig. 3 is yoke ring punching figure of the present utility model.
As shown in Figure 1, a kind of latent salient pole capacitor motor, its stator is assembled after laminating by yoke ring sheet 2 and salient pole sheet 7, and 3 is the principal phase coil, and 6 is auxilliary phase coil.As shown in Figure 2, the pole tip of each adjacent pole links to each other successively, smooth, the whole salient pole of interior circle becomes one.8 cut oblique arc for pole tip.As shown in Figure 3, the inner edge of yoke ring sheet 2 dashes at the magnetic pole place to have and press-fits the corresponding magnetic pole holddown groove 10 of salient pole shape size that use and the salient pole root.1 is casing, and 4 is rotor, and 5 are rotating shaft, and 9 is base.
