Description
Technical field
The utility model relates to a kind of low noise alternating current machine, belongs to the manufacturing technology field of motor.
Background technology
Motor is used more and more wider in people's life, as air conditioner motor, motor for washer, refrigerator motor or the like, so wide application, big consumption like this, make the technology upgrading of motor that considerable economic be arranged, be upgraded to concentrated winding electric machine from traditional distributed winding motor, all can reduce greatly with iron amount and copper consumption, promote Enterprises'Competitiveness, but the noise problem of plastic packaging motor restricts its development always, how effectively to solve the noise problem of concentrating winding electric machine, become the obstacle of concentrating the winding electric machine development to go beyond.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and is simple in structure, can effectively improve the operation noise of motor, the low noise alternating current machine that improves the quality of products.
The utility model is the low noise alternating current machine, comprise casing, place front end housing and the rear end cap of establishing bearing in the casing two ends, place the rotor core of band power transmission shaft in the casing, be fixed in the plastic packaging stator that constitutes by stator core and winding on the casing inner wall, it is characterized in that offering the V-arrangement skewed slot on the periphery of rotor core, the angle of V-arrangement skewed slot is 83～122 degree; Stator core is made of the stator core stamping sheet closed assembly, offers virtual groove on the pole shoe of stator core stamping sheet bottom; Be respectively equipped with the ripple bullet between bearing and front end housing, the rear end cap.
The degree of depth of described V-arrangement skewed slot can be 12 ± 2mm.
The axis hole both sides of described rotor core also can offer the groove concentric with axis hole respectively, and the diameter of groove is 1.2～1.8 times of shaft hole diameter, and the degree of depth is 1.5～2mm.
The offer quantity of described virtual groove on pole shoe can be 1～3.
The two ends up and down of described casing also can be provided with installation foot and installing hole.
The utility model provides the thinking of comprehensive reduction motor noise at the source that motor noise takes place from aspects such as rotor, stator, rotor general assemblies, can reduce the noise that motor produces greatly.Compared with prior art, have following outstanding advantage and good effect:
1, on rotor, by offer the V-arrangement skewed slot on the periphery of rotor core, cutting magnetic induction should caused axial force influence when having eliminated the rotor rotation, has improved the stress that rotor winding transverse current causes, can effectively reduce the operation noise of motor.Simultaneously, offer the groove concentric respectively with axis hole in the axis hole both sides of rotor core, in the time of effectively preventing rotor core die casting to the harmful effect of iron core end.
2, on stator, by add virtual groove on the stator core pole shoe, the operation principle of virtual groove is that the frequency of slot ripples is low, the amplitude height; The frequency height, amplitude is low, and the high more hot-tempered sound of amplitude is big more, makes the slot ripples frequency gets higher by adding virtual groove, and amplitude reduces, thereby reduces hot-tempered sound.
3, from the motor general assembly, the rotor axial play reduces motor noise when utilizing the ripple bullet to suppress motor rotation.Because the ripple bullet is given pretightning force of rolling bearing, also eliminated the noise that produces when turn round in the ball gap.
After the improvement of carrying out aspect above-mentioned three, effect of the present utility model is significantly to have improved motor noise, makes motor rotation reach maximum low noise.
