Abstract

The rotor (1) has parallel sided slots (2) which are wider at their open end than at the bottom. This shape is stated to be suitable for use with inexpensive aluminium windings instead of copper windings without impairing the performance characteristic. The rotor may be formed of laminated plates, or metal strips wound edgeways; and the windings may be shaped to fit the groove and have an impregnating agent applied to them in the slots. <IMAGE>
