Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: as shown in Figure 1, comprises bearing 1, front end housing 2, rotating shaft 3, terminal box 4, suspension ring 5, stator core 6, rotor 7, stator winding 8, support 9, rear end cap 10, fan housing 11 and fan 12; Described bearing 1 one end is fixed with rotating shaft 3 and described bearing 1 bottom is provided with front end housing 2, described rotating shaft 3 side close contact terminal box 4, described terminal box 4 one end is provided with stator core 6, and described stator core 6 external stability is provided with rotor 7, described rotor 7 top is provided with suspension ring 5, described stator core 6 side is fixedly connected with stator winding 8 and described stator winding 8 top is provided with support 9, and described support 9 bottom is provided with rear end cap 10.
As a kind of optimal technical scheme of the present utility model, described bearing 1 is for cirque structure and described bearing 1 side is provided with stator winding 8; Described rotor 7 is cylindrical structural and described rotor 7 is fixedly connected with terminal box 4; Described support 9 side is fixedly connected with fan housing 11; Described fan housing 11 inside fixed installation fan 12.
The utility model institute in use, when passing into symmetrical three-phase alternating current in threephase stator winding 8, just creating one and making right handed rotating magnetic field with synchronous speed n1 along space of circles in 6 stators and rotators 7.Because rotating magnetic field rotates with n1 rotating speed, be static when rotor conductor starts, therefore cutting stator rotating magnetic field is produced induced electromotive force by rotor conductor.Because rotor conductor two ends are shorted ring short circuit, under the effect of induced electromotive force, in rotor conductor, the induced current basically identical with induced electromotive force direction will be produced.The current－carrying conductor of rotor 7 is subject to the effect of electromagnetic force in stator 6 magnetic field.Electromagnetic force produces electromagnetic torque to rotor 7 axle, drives rotor to rotate along rotating magnetic field direction.When the threephase stator winding 8 of motor, after passing into three-phase symmetrical alternating current, by generation rotating magnetic field, this rotating magnetic field cutting rotor winding, thus induced current is produced in rotor windings, the rotor conductor of current-carrying will produce electromagnetic force under the effect of stator rotating magnetic field, thus form electromagnetic torque on machine shaft, drive motor rotates, and motor direction of rotation is identical with rotating magnetic field direction.
