What I claim as new and desire to secure byġ. When alloy materials are used, the major alloying material or materials, in terms of percentage by weight of the alloy, comprise a sufficiently large percent of the alloy (by weight) that normal manufacturing and processing variations causing variations in the amount of such alloying material or materials still permit the economical manufacture of an alloy having a desired nominal resistivity. Preferred auxiliary winding materials have an electrical conductivity of about 29% IACS (International Annealed Copper Standard), a density of about 0.1 pound per cubic inch, and a specific heat at 25° Centigrade of about 0.2 calories per gram per degree Centigrade.

Each starting winding is formed of a material that yields the same motor operating performance as a copper starting winding design with a backlash section and yet is provided with fewer, if any, backlash turns as compared to such copper winding arrangement. Auxiliary winding in form of a starting winding also includes at least two sections forming poles angularly displaced from the main poles.

Main winding comprises at least two sections each forming a main pole. Stator assembly for a motor includes slotted magnetic core with main and auxiliary windings in core slots.
