Abstract
The shaft for a rotating electrical machine comprises at least one housing element (8a, 8b, 8c) extending in an axial direction (A) and emerging outwards in a radial direction, with one side of the housing element emerging outwards in an axial direction, and with the housing being able to accommodate at least one insulated electrical conductor (6) and a spacer (9a, 9b, 9c).
Claims14
A shaft for a rotating electrical machine, comprising:
- at least one housing element disposed external to the shaft and formed of a groove extending lengthwise in an axial direction of the shaft and having one side thereof extending outwards in a radial direction of the shaft, wherein the at least one housing element comprising a spacer and configured to accommodate at least one insulated electrical conductor and the spacer;
- and
- at least one ring to be inserted onto the shaft in the axial direction wherein the spacer is positioned between the at least one insulated electrical conductor and ring to compensate for space between the ring and the at least one insulated electrical conductor to prevent movement thereof.
A rotor for a rotating electrical machine comprising a shaft, wherein the shaft comprising:
- a plurality of housing elements disposed external to the shaft and formed of a groove extending lengthwise in an axial direction of the shaft and each having on side thereof extending outwards in a radial direction of the shaft, and each housing element comprising a spacer and a portion for accommodating at least one insulated electrical conductor and the spacer;
- and
- wherein the rotor includes insulated electrical conductors so that each portion comprises the same number of electrical conductors so as to fill each portion.
