The utility model provides the Y160-2_15KW type synchronous high-efficiency motor with lower cost.
Description
Technical field
The utility model relates to machine field, relates in particular to the permanent magnet generator that a kind of specification is the Y160-2_15Kw type.
Background technology
Existing Y160-2_15Kw type permanent magnet generator adopts the load wye connection; Its structure comprises the rotor core that rotates assembling on the stator core that is connected on housing, the housing and the housing; The length of stator core is 190mm; Have stator slot on the stator core, the technical data of wherein corresponding iron core and winding has, and the number of stator slot is 30; The stator winding connected mode is: concentric winding; Be wound with six great circles and a ringlet on the stator slot, great circle is made up of the coil of certain number of turn, and ringlet is made up of the coil of certain number of turn.But, finally cause the cost of existing Y160-2_15Kw type permanent magnet generator higher owing to the coil turn of the large and small circle of composition of existing Y160-2_15Kw type permanent magnet generator, constitute the unreasonable design of unreasonable and stator core length of wire gauge of each coil and unreasonable.
Summary of the invention
The purpose of the utility model is to provide a kind of lower-cost Y160-2_15Kw type permanent magnet generator.
In order to address the above problem, the technical scheme of the utility model is:
Permanent magnet generator; Comprise the rotor core that rotates assembling on the stator core that is connected on housing, the housing and the housing, have stator slot on the stator core, the number of wherein said stator slot is 30; Be wound with six great circles and a ringlet on the stator slot, the length of stator core is 140mm; Described each great circle is formed by 7 circle coils, and described ringlet is made up of 4 circle coils, and the every circle coil that constitutes great circle and the every circle coil that constitutes ringlet are by three diameters lead that is 1.35mm and around forming.
Gas length between said stator core and rotor core is 0.3mm.
Described stator core and rotor core are formed by a plurality of DR510-50,50WW600 or 50WW470 silicon steel sheet.
Described rotor core is that the N38SH type permanent magnet of 8mm constitutes by a plurality of thickness.
The beneficial effect of the utility model is: the utility model is through more rationally confirming to constitute the coil turn and the wire gauge that constitutes every circle coil of each great circle and ringlet; Make the length of stator core can reduce to 140mm, and then saved the cost of Y160-2_15Kw type permanent magnet generator.And after process was to corresponding data adjustment, Y160-2_15Kw type permanent magnet generator still can reach about 95%.
