segment coil, process for the preparation of a wire rod segment coil, for a segment coil and the stator.

摘要

It is a segment coil are made available which is capable of an effective prevention of a magnetic power flux leakage or by eddy current to reach and to increase the efficiency of a motor. Segmental coils (4a, 5a) in a stator of a rotating electrical machine, of a toroidal core, and rectangular wire windings in a plurality of layers, a in the radial direction in an inner circumferential portion of the toroidal core of a slit on an innermost peripheral side and a rotor are arranged opposite one another, are in each case of a plurality of in the circumferential direction of the toroidal core is divided so many sub-filaments (11, 12, 13). The plurality of so many sub-filaments (11, 12, 13) are emitted from the slot coil end (e1) is connected as a unit.
