Specific embodiment
Accompanying drawing in below in conjunction with the embodiment of the present invention, to the embodiment of the present invention in technical scheme carry out clearly and completely
Description, it is clear that described embodiment a part of embodiment only of the invention, rather than whole embodiments.Based on this
Embodiment in invention, the every other reality obtained under the premise of creative work is not made by those of ordinary skill in the art
Example is applied, the scope of protection of the invention is belonged to.Additionally, protection scope of the present invention should not only be limited to following concrete
Structure or part or design parameter.
A kind of new motor double speed simplex winding, using single speed simplex winding speed regulating method, speed is divided into two grades, and low or first gear is adopted
Whole windings, top gear are used to adopt part winding, it is characterised in that：During rule, embedding first A ' X ', B ' Y ', C ' Z ' three-phase windings
In bottom land part, further according to corresponding groove number, embedding AX, BY, CZ three-phase windings part on the groove；Upper and lower part in same groove
Must be separated with layer insulation between coil, end is separated using overhang insulation.
During low or first gear wiring of the present invention, winding A ' X ' are connected with winding AX, X and A ' short circuits, connect lead from A points
Go out for U1；Winding B ' Y ' are connected with winding BY, Y and B ' short circuits, are connect lead from B points and are gone out for V1；Winding C ' Z ' and winding CZ
Connected, Z and C ' short circuits connect lead from C points and go out for W1；Remaining X ', Y ', Z ' point is connected into asterism for N.
During top gear wiring of the present invention, X and A ' short circuits, connect lead-out wire for U2, Y and B respectively ' short circuit, connect lead-out wire
For V2, Z and C ' short circuit, lead-out wire is connect for W2, remaining X ', Y ', Z ' and point is connected into asterism for N, and remaining A, B, C point is vacant.
Using single speed simplex winding speed-regulating scheme, low or first gear adopts whole windings, and top gear adopts part winding, by reasonable
Design, can obtain preferable performance in full frequency band.Specially：First, using a set of winding by changing connection and tap.1.U1、
