Abstract
The utility model relates to a kind of asynchronous machine, particularly a kind of 8/10 utmost point pole-changing asynchronous machine.Comprise front and rear cover, casing, stator core, be arranged on rotor core and fan on armature spindle, described stator winding adopts 4Y/3Y or 3Y/3Y syndeton.The utility model has adopted new stator winding syndeton, reduces motor harmonic field, and therefore vibrations and noise are all less; And reduce starting current, the electric current while greatly reducing shift speed change and temperature of rotor, the effect that reached power saving, increases useful life, enhances productivity.
Description
Technical field
The utility model relates to a kind of asynchronous machine, particularly a kind of 8/10 utmost point pole-changing asynchronous machine.
Background technology
For meeting the current supporting needs to class plant equipment, variable-pole multi-speed motor is widely used day by day, particularly not high to some adjusting speed accuracies, do not need the equipment of stepless time adjustment, as the equipment such as blower fan, mixer, compare with the variable speed electric motors, particularly that adopts other speed regulating methods, variable-pole multi-speed motor is squirrel-cage motor, adopt distal pole to compare pole changing, there is no brushgear easy to wear, also needn't another attached speed regulating device, have cost low, control the advantages such as simple, easy to maintenance, therefore there are wide market prospects.
Utility model content
Technical problem to be solved in the utility model has been to provide a kind of 8/10 utmost point pole-changing asynchronous machine, and the stator winding syndeton of existing asynchronous machine is improved.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of 8/10 utmost point pole-changing asynchronous machine, comprise front and rear cover, casing, stator core, be arranged on rotor core and fan on armature spindle, described stator winding adopts 4Y/3Y or 3Y/3Y syndeton; 8 grades of windings and 10 grades of windings are set in the groove of described stator core; Between described 8 grades of windings and 10 grades of windings, be provided with insulation board; Described 8 grades of windings and 10 grades of windings are symmetric setting.
On the basis of technique scheme, the utility model can also do following improvement.
Further, the groove number of described stator core is 60 or 72 grooves.
Further, described casing is provided with heat dissipation ventilation road.
The beneficial effects of the utility model are: the utility model has adopted new stator winding syndeton, reduces motor harmonic field, and therefore vibrations and noise are all less; And reduce starting current, the electric current while greatly reducing shift speed change and temperature of rotor, the effect that reached power saving, increases useful life, enhances productivity.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model asynchronous machine.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, for the structural representation of the utility model asynchronous machine, comprise armature spindle 1, end cap 2, casing 3, fan 4, stator core 5, rotor core 6 and stator winding 7, described rotor core 6 and fan 4 are arranged on armature spindle 1, and described stator winding 7 adopts 4Y/3Y or 3Y/3Y syndeton.In the present embodiment, 8 grades of windings and 10 grades of windings are set in the groove of described stator core 5, between described 8 grades of windings and 10 grades of windings, are provided with insulation board; Described 8 grades of windings and 10 grades of windings are symmetric setting.The present embodiment, the groove number of described stator core is 60 grooves, in other embodiments, the groove number of described stator core is 72 grooves.Preferably, in the present embodiment, described casing is provided with heat dissipation ventilation road.
The utility model has adopted new stator winding syndeton, reduces motor harmonic field, and therefore vibrations and noise are all less; And reduce starting current, the electric current while greatly reducing shift speed change and temperature of rotor, the effect that reached power saving, increases useful life, enhances productivity.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
