Background technology

At present, employed on the market motor mainly is motor with cup rotor and capacitor motor, and the motor with cup rotor volume is big, revolutional slip is big, and power factor is generally 0.36-0.6, and its efficient is generally 4%-17%, and be folk prescription to operation, capacitor motor also is that volume is big, complex structure, complex manufacturing technology, manufacturing cost height, speed adjusting performance is poor, and starting current is big, it is rated current 3-5 times, therefore power consumption is big, and does not allow that long-time property starts repeatedly, and interruption of service is more.

Summary of the invention

The object of the present invention is to provide a kind of capacity regulating salient-pole AC single phase capacitor motor, its manufacture craft is simple, simple and compact for structure, cost is low, high efficiency and security of operation.

In order to realize such scheme, technical solution of the present invention is: a kind of salient-pole AC single phase capacitor motor, comprise the stator that is made of stator inner iron core, the outer iron core of stator and machine winding coil, the rotor that is positioned at described stator center hole, described rotor center is associated with motor shaft; The winding coil of described stator connects adjustable capacitor by lead; Described stator inner iron core is provided with the convex magnetic pole bodies, is loaded on the outer inside unshakable in one's determination of stator, and winding coil is set on the described convex magnetic pole bodies, and is loaded in the lump in the outer iron core of stator with the stator inner iron core.

Above-mentioned salient-pole AC single phase capacitor motor, improvement is: the stator inner iron core is that one group of convex pole piece is overrided to form, and the inner edge of convex pole piece is smooth circular port, and its outer rim is evenly distributed with the convex magnetic pole; The end of described convex magnetic pole offers the half slot that is used to locate; Described convex pole piece forms the convex magnetic pole bodies by stack, and there is the smooth cambered surface of an outside sweep junction between adjacent convex magnetic pole.

Above-mentioned salient-pole AC single phase capacitor motor, further improvement also is: the convex pole piece has four convex magnetic poles, is equipped with connecting hole on each convex magnetic pole, and rivet passes described connecting hole each convex pole piece is fixed as one.

After adopting such scheme, when salient-pole AC single phase capacitor motor of the present invention is made, the connecting hole that passes on each convex pole piece with rivet is riveted earlier, all convex pole pieces are become one form the stator inner iron core, all convex magnetic poles are combined into the convex magnetic pole bodies, winding coil is sleeved on the convex magnetic pole bodies again, rivet with the connecting hole that rivet passes on the outer yoke ring sheet unshakable in one's determination of each stator, the outer yoke sheet unshakable in one's determination of all stators is become one form the outer iron core of stator, the stator inner iron core that will be set with winding coil then is pressed in the outer iron core of stator, the convex magnetic pole bodies end that makes the phasing inner iron core is corresponding in the outer link slot unshakable in one's determination of stator, make the place, spill semicircle location of stator inner iron core corresponding with place, the outer convex semicircle location unshakable in one's determination of stator, and with town's pin pass on the outer iron core of stator pilot hole and before, rear end cap is linked and packed and is one, finishes to this motor assembling.At last adjustable capacitor is connected with winding coil with lead, the present invention structurally motor body materials is few, and volume is little in light weight, and its magnetic pole is installed as the concentricity height, and magnetic pole is distributed symmetrically, and the magnetic circuit distributing homogeneity is strong; Magnetic electricity, magnetic conversion efficiency height; Electric efficiency improves 1.5-2 doubly with the capacity motor with cup rotor, improves about 15% with the capacity motor.
