ABSTRACT:
A rotating starting resistance for a rotating electrical machine is disclosed. The resistance includes a helicoidal resistance wire that is wound in the shape of a torus, and connected to the rotating shaft of the electrical machine. The resistance wire may be directly fastened to a supporting member by means of a glass fiber cord suitably impregnated with a synthetic resin. The helicoidal nature of the starting resistance permits efficient cooling, and allows minimization of the overall height of the resistance. The resistance wire, which is wound in the shape of a helicoidal torus, may be reinforced at either the inner or outer diameter of the torus.
