Abstract

An inductive electric machine such as an induction motor or a transformer having field and rotor cores, or, respectively, primary and secondary cores, each such core being formed of metal strip (204) punched to have a plurality of holes spaced and located at predetermined positions along the strip (204) so that, when the strip is wound about a central axis, the holes (205, 208, 209) are located so as to form radially extending slots (205, 208, 209) on a face of each such core. Windings (213) can be placed in the slots of the field core and in the slots of transformer cores. A conductor (206) can be placed in the slots of the rotor core.
