On-vehicle multiphase synchronous electric machine for mutual conversion between kinetic energy and electric energy, assembling method thereof, and vehicle equipped with the electric machine

摘要

A multiphase synchronous electrical machine (1) for converting kinetic energy into electrical energy and electrical energy into kinetic energy has a rotor (4) extending along an axis (A), and a stator (5), which is provided with a stator pack (25) having slots (27) and with an electrical winding (26), which extends in part in the slots (27) and in part in a position corresponding to two heads (28, 29) arranged on opposite sides of the stator pack (25) and has bars (30, 31, 32, 33) housed in the slots (27) and connected to one another in a position corresponding to the heads (28, 29) and connection plates (46, 47, 48, 49, 51, 52, 53), which are welded to the bars (30, 31, 32, 33), are packed with respect to one another and to the stator pack (25) in an axial direction and are shaped in such a way as to define a prolongation of the stator pack (25).
