Abstract

1494384 Making dynamo-electric machines LUCAS ELECTRICAL Ltd 12 April 1975 15120/75 Addition to 1398518 Heading B3A In a method of making a dynamo-electric machine rotor assembly as disclosed and claimed in parent Specification the conductors of the armature assembly are deformed to define portions which after insertion of the winding ends into respective apertures, lie in the planes of the apertures and so provide within each aperture a conductor area engaged by a subsequently formed commutator segment. The step of metal spraying additionally comprises a first spraying operation to deposit a first metal of good electrical conductivity, e.g. aluminium or aluminium alloy, into each aperture to build up a segment base and a second spraying operation in which a layer of copper is sprayed on each segment base to define the surface of the commutator.
