Title: Fixing method of coil end
Inventor: YASAKA YASUHIRO
IPC: H02K3/51
Filed: 1987-04-30
Abstract: PURPOSE:To reduce the eddy currents of a binding wire generated by the AC excitation of coils by manufacturing a spacer between the coils by a metal having conductivity. CONSTITUTION:An underlay 2 is mounted under a binding wire 1, and a spacer 5 made of a metal is inserted between coils 3. An underlay 6 is positioned on the lower side of the coils 3, and the coil 3 is also arranged under the underlay 6 similarly. A spacer made of duralmin is used as the spacer 5 made of the metal at that time. Since duralmin has considerably large conductivity, eddy currents flow through duralmin itself and a leakage magnetic field is reduced when AC currents flow through the coil windings 3, thus lowering the temperature rise of the binding wire 1. Thermal conductivity is also made extremely large, thus lowering the temperature rise of the coils.
