The two ends of said stator iron core are positioned at each arc cylinder place and are equipped with connecting hole; Described each arc locating piece is equipped with the connecting through hole corresponding with connecting hole; Described electric motor end cap is linked together through connecting through hole and connecting hole and stator core and casing by connecting screw.
Above-mentioned electric motor end cap is provided with end-cover axle bearing room; Described end-cover axle bearing room comprises annular side, the annular bottom surface vertical with annular side and forms the bullet pad doughnut of transition with annular bottom surface; The bottom center of described bullet pad doughnut is provided with wears axis hole; The sidewall that described bullet pad doughnut is connected with annular bottom surface transition is taper seat; Described bullet pad doughnut is circular cone shape, and sidewall closes up to wearing axis hole end; Described annular side, annular bottom surface, bullet pad doughnut and to wear axis hole all coaxial.
The angle of the sidewall that above-mentioned bullet pad doughnut is connected with annular bottom surface transition and annular bottom surface is 20 °.
The face of cylinder of said stator iron core is provided with four tangent planes; Described coaxial positioning block group comprises four arc locating pieces.
The utility model has positive effect: (1) the utility model can ensure the axiality of stator core and electric motor end cap by the arc locating piece on electric motor end cap, also ensure that the axiality of rotor and stator and electric motor end cap simultaneously, thus ensure that the air gap of stator and rotor is even, realize the optimum of motor performance; (2) connecting through hole in the utility model on arc locating piece is corresponding with the connecting hole on stator core, just can be ensured the axiality of stator core and electric motor end cap when assembling by direct connection; (3) the utility model sidewall of being connected with annular bottom surface transition of pad doughnut of being hit by a bullet is taper seat, solves the problem that corrugated gasket easily blocks when installation corrugated gasket, improves installation rate; (4) the utility model is hit by a bullet the pad sidewall of doughnut and the angle of annular bottom surface when being 20 °, and result of use is best.
