A coupling between a prime mover and a dynamoelectric machine should include electrical insulation between the connected shafts so as to preclude the transmission of eddy currents between the dynamoelectric machine to the prime mover shaft. This insulation may be provided at the radial interface between coupling members. However, it has been found that the torque carrying capability of a coupling may be enhanced by providing a circumferential electrical insulation between radially inner and outer hubs which comprise the coupling member on the dynamoelectric machine side of the coupling. |
