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. | |
