Embodiment
The present invention is further illustrated below in conjunction with Figure of description.
As shown in the figure; the two rotating speed monopole asynchronous motor of 10w comprises the accommodating cavity be made up of front end housing 13, rear end cap 3; be arranged on the stator core 9 in accommodating cavity; be arranged on the rotor core 8 in stator core 9; be arranged on the mouse cage winding in rotor core 8 and end ring 7; the rotating shaft 15 be fixedly connected with rotor core 8, is arranged on the stator winding 16 in stator core 9 and thermal protector 6.Rotating shaft 15 is supported by the ball bearing 5 be arranged in front end housing 13, rear end cap 3, and is fixed by snap ring 14.Ball bearing 5 and front end housing 13, rear end cap 3 cooperation place arrange wave washer 4.Stator winding 16 is connected lead-out wire 1 with thermal protector 6, lead-out wire 1 outer socket sheath 2.
Stator winding 16 comprises main winding 10, auxiliary winding 12 and tap winding 11; thermal protector 6 circuit connects main winding 10; main winding 10 circuit connects tap winding 11; tap winding 11 circuit auxiliary connection winding 12; lead-out wire 1 is connected between main winding 10 and tap winding 11 and between tap winding 11 and auxiliary winding 12; extraction connects power end (i.e. lead-out wire 1), connects electric capacity C between thermal protector 6 and auxiliary winding 12.Tap winding 11 is parafacies L-type tap winding, change the turn ratio of tap winding 11 and auxiliary winding 12, speed difference fast and at a slow speed can be changed, tap winding 11 and auxiliary winding 12 are placed in same groove, main winding 10 and auxiliary winding 12 are spatially at a distance of 90o electrical degree, number of stator slots is 16 grooves, 4 poles, main winding 10 accounts for 8 grooves, auxiliary winding 12 accounts for 8 grooves, major-minor winding equiphase zone, respectively account for 90o electrical degree, because major-minor winding is all Working winding when starting and operate, substantially close to circular rotating field during to operate, in order to obtain enough large starting torque and starting current little as far as possible, also to make the operation voltage of terminal voltage Uc close to motor of capacitor during running, consider that each winding temperature rise should be more even, major-minor winding has identical current density as far as possible, the secondary effective turn ratio a of main winding of choose reasonable and capacitor c value, a is taken as 1.2 ~ 2, C=1/(2 π f Xc).Thermal protector 6 specification is BW-125oC, when winding temperature reaches 125oC, disconnects main winding 10 loop, after temperature declines, automatically connects main winding 10 loop, plays the effect of overtemperature protection.Rotor number is 22 grooves, and rotor is cage-shaped structure, and rotor chute, apart from being 1.5 times of rotor slot-pitches, weakens the slot ripples producing additional torque.
