Electric machine i.e. three-phase alternate current generator, for motor car, has groove portion arranged radially outside beyond tooth portion of electromagnetic, symmetrically formed tooth, where tooth portion is limited by groove walls

摘要

The machine (10) has a stator winding (18) i.e. pull-in winding, inserted in radially inwardly directed and axially extending grooves of an annular stator iron (17) of a stator (16). An electromagnetic, symmetrically formed tooth comprises a tooth portion that is limited by groove walls with side surfaces that are parallel to each other. A groove portion with parallel side surfaces is arranged radially outside beyond the tooth portion. The groove and the tooth are arranged adjacent to each other. Wires of the stator winding are enclosed in one of the grooves.
