Abstract
A dynamoelectric machine having a rotor carrying a field coil has a fan and slip ring assembly formed from a thermoplastic material into a unitary structure. A slip ring portion is axially remote from the fan portion, the two portions being connected by thermoplastic material which is formed to cooperate with the rotor shaft to provide channels for capturing coil leads of the field coil.
Claims3
A fan and slip ring assembly for a dynamoelectric machine comprising:
- a rotor for said dynamoelectric machine, said rotor comprising a rotatable shaft along a longitudinal axis and a field coil having a pair of coil leads;
- a fan having a central aperture through which the shaft and the pair of coil leads pass;
- a pair of slip rings longitudinally spaced from said fan and having respective coupling terminals;
- connecting means for connecting said fan to said pair of slip rings;
- said rotor shaft and said connecting means cooperating to form a pair of closed longitudinal channels, each one of said pair of coil leads passing through a respective one of said pair of closed longitudinal channels and coupled to a respective one of said coupling terminals.
