Embodiment
below in conjunction with drawings and Examples, the invention will be further described:
a kind of energy-saving type air conditioner electric moto used in compressor assembly as shown in Figure 1, comprise stator 1, the rotor 2 be complementary with stator 1 and the rotating shaft be complementary with rotor 2.
in the present embodiment: stator 1 is by a plurality of stator lasmination closed assemblies, rotor 2 is by a plurality of rotor pack closed assemblies, and the use material silicon steel disc WW800 that stator lasmination, rotor pack discard tradition, adopt silicon steel sheet DW470, reduces stator 1, rotor 2 loss at work.In the lamination process of stator lasmination, rotor pack, the Chinese patent " a kind of moulding die " that the publication number that adopts applicant's application is 102035312A carries out auto-tensioning, and automatic pressure regulation is controlled, infrared electro is measured folded high, thereby the insulating barrier between the assurance lamination does not destroy, reduce iron loss and eddy current between slice, thin piece, thereby improve the electric efficiency index.
as shown in Fig. 4-6: on the rotor 2 after lamination, offer axis hole 20, be controlled at ± 0.009mm of the precision of axis hole 20, adopt round broach pulling eye, extruding hobboing cutter to roll hole, make the axis hole surface roughness reach 0.8mm, improve precision, the motor Energy Efficiency Ratio of motor, reduced loss, noise and vibration simultaneously.
the two ends of rotor 2 are provided with aluminium end ring 21, directly are connected to the balance riveting pin 22 on aluminium end ring 21, balance weight 23 is connected on aluminium end ring 21 by balance riveting pin 22, and like this, balance weight 23 riveting accurately is on aluminium end ring 21, improve the degree of balance of rotor 2, reduce motor noise, vibration.
after stator 1, rotor 2 and rotating shaft are installed, rotor 2 is assemblied in stator 1, rotating shaft is arranged in the axis hole 20 of rotor 2, in the situation that do not increase the motor external diameter, the maximum length of stator 1, rotor 2 is not more than 125mm, improve power of motor by the length that increases stator 1, rotor, and make the external diameter of motor be not more than 172mm.
