Method for manufacturing stator or rotor for electric machine involves inserting wave windings of rectangular coil wire into grooves that have rectangular cross-section and are provided in core

摘要

The method involves inserting wave windings (10) of rectangular coil wire into grooves that are open on the inside or on the outside and have a rectangular cross-section and are provided in the core (12) of the stator or rotor. The cross-sections of the coil wire form with several radial layers a row that extends along the groove and fill in the cross-section of the groove. Independent claims are also provided for (1) Arrangement for manufacturing stator or rotor (2) Stator.
