Abstract

According to one embodiment, there is provided a rotating electrical machine coil with a conductor and an insulation layer that is provided around the conductor to cover the conductor, the rotating electrical machine coil including a linear part of the coil and a coil end that is separable from and electrically connectable to the linear part of the coil.

Claims1

Dependent claims

A rotating electrical machine coil with a conductor and an insulation layer that is provided around the conductor to cover the conductor, the rotating electrical machine coil comprising:

a linear part of the coil:
and
a coil end that is separable from and electrically connectable to the linear part of the coil:
wherein the coil end is electrically connectable with the linear part of the coil via an adapter having electrical conductivity;
and
wherein a field alleviating layer is provided in a field convergence portion in at least one of a connection portion between the linear part of the coil and one end of the adapter or an electrical connection portion between the coil end and another end of the adapter.
