The assembled remaining N-1 of axial double wedge（N=number of slots）Individual piece stator；Lower position nut is screwed into pressure first after the completion of assembly
The thread root of bar bolt, then platen is penetrated into depression bar bolt, treat stator positioning spigot and the piece stator upper end at platen edge
After face is worked good, upper limit nut is tightened, then by the lightening hole on platen, is extend into below platen, then by lower limit spiral shell
Mother is screwed onto the lower surface of platen, plays a part of fixed platen, to ensure stator piece impaction state；By the axle on piece stator
Unclamped successively to the nut on screw rod, axial screw is extracted out；Stator upper head plate is put, then axial screw is set up, spiral shell is tightened
Mother, completes the assembling of whole stator.
The more current stator assembling technique of magneto piece stator assembling is shortening the production cycle and is improving product
Can on have very big advantage.Have the advantage that compared with prior art as follows：
1st, magneto piece stator splicing accuracy is improved, the insulation harm of motor is reduced.
2nd, the production cycle of assembled stator piece is shortened, operating efficiency is improved.
3rd, the labor intensity of workman is reduced.
After magneto piece stator assembling, it is ensured that the internal-and external diameter tolerance satisfaction after stator assembly is got up is set
Meter is required, so as to ensure that magneto air gap reaches design requirement, and meets the build-up tolerance of permanent magnet motor stator and housing.
