Stator unit for electric motor, has laminated core made from insulated sheet metals, and coaxial studs formed at end plates, where diameter of studs has over size relative to through holes and studs are pressed in to through holes

摘要

The stator unit has stator laminated core made from insulated sheet metals, and end plate with an earth conductor connection attached to the core. The sheet metals include stamped-in holes, which form axially parallel through holes (6) at the laminated core. Coaxial studs (7) are formed at the end plates, where diameter of the stud have an over size relative to the through holes and the studs are pressed in to the through holes.
