Abstract

The model utility relates to a squirrel cage type air conditioned compressor motor rotator. A cast aluminum rotator with a guide groove inserted by copper guide bars mainly comprises a squirrel cage type air conditioned compressor motor rotator, this rotator mainly includes rotator punching overlays and cast aluminum end rings and rotator shaft. The said rotator punching pieces are punched with guide bar holes forming a circle of guide bar groove after such holes are overlaid, copper bars are inserted into the said guide bar groove and other parts of the guide bar groove also are filled with cast aluminum. After the guide bar groove of the squirrel cage type motor rotator is inserted with copper bars, the resistances of the squirrel cage type motor rotator and consumption is reduced so as to improve the efficiency of the motor and the cast aluminum equipments are no need to be rebuilt.

Description

The cast-aluminum rotor of copper sliver is gone in the intercalation of sliver groove

Technical field

The utility model relates to squirrel cage motor, specifically refers to the improvement to squirrel-cage compressor of air conditioner apparatus for cast-aluminium rotor of electric machine.

Background technology

Existing squirrel cage motor normally adopts cast aluminium to make rotor end ring, while cast aluminium in the sliver groove of rotor pack, thus make electric current in rotor, form the loop, but because the resistivity of aluminium is higher, so rotor loss is big, causes electric efficiency to reduce.

Summary of the invention

The purpose of this utility model is to propose the cast-aluminum rotor that the copper sliver is gone in the intercalation of a kind of sliver groove, by at the lower copper sliver of the embedded insertion conductance of sliver groove, and with the part cast aluminium in the alternative sliver groove, thus the efficient of raising cast-in aluminum squirrel cage rotor electric machine.

The cast-aluminum rotor of copper sliver is gone in a kind of sliver groove of the present utility model intercalation, mainly comprise a squirrel-cage compressor of air conditioner rotor, this rotor mainly is made up of the cast aluminium end ring and the armature spindle at rotor punching lamination and two ends, described rotor punching upper punch has a circle to build up the sliver hole that the back forms a circle sliver groove mutually, the copper sliver is gone in intercalation in described sliver groove, and other parts are still filled cast aluminium in the sliver groove.

Effect of the present utility model is: after inserting the copper sliver in the sliver groove of squirrel cage motor rotor, can reduce resistance, the minimizing loss of cage rotor, electric efficiency be improved, and do not need cast aluminium equipment is carried out big transformation.

Description of drawings

Fig. 1 is a rotor schematic diagram of the present utility model;

Fig. 2 is the silicon steel punched chip schematic diagram of the rotor of Fig. 1.

Among the figure: 1 cast aluminium end ring, 2 rotor core punchings, 3 sliver holes, 4 slivers, 5 rotor shaft hatchs.

Execution mode

Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.

By Fig. 1, Fig. 2, squirrel cage motor rotor of the present utility model, mainly form by rotor punching lamination 2 and the cast aluminium end ring 1 and the armature spindle at two ends, described rotor punching 2 upper punches have a circle dumbbell shaped sliver hole 3, described sliver hole 3 builds up the back mutually and forms inside and outside two circle sliver grooves, form a two squirrel cage motor rotor, the interior ring recess 3a of sliver groove or outside among the ring recess 3b intercalation go into the copper sliver, also can be in interior ring recess 3a and outer ring recess 3b all intercalation go into the copper sliver, interior other parts of sliver groove are still filled cast aluminium.

Claims

1. the cast-aluminum rotor of copper sliver is gone in sliver groove intercalation, mainly comprise a squirrel cage motor rotor, this rotor mainly is made up of the cast aluminium end ring and the armature spindle at rotor punching lamination and two ends, described rotor punching upper punch has a circle to build up the sliver hole that the back forms a circle sliver groove mutually, it is characterized in that the copper sliver is gone in intercalation in described sliver groove, other partially filled cast aluminiums in the sliver groove.

2. the cast-aluminum rotor of copper sliver is gone in sliver groove according to claim 1 intercalation, it is characterized in that being dumbbell shaped at described sliver groove, the interior ring recess of this dumbbell shaped sliver groove or outside in the ring recess, or the copper sliver is gone in equal intercalation in interior ring recess and the outer ring recess.
