Abstract:
1. An electric machine which comprises: two coaxial structures which are configured so that one of the two coaxial structures rotates relative to another of the two coaxial structures about a common central axis; a plurality of slots provided in a peripheral surface of one of said two coaxial structures, said slots having central axes which are parallel to the common central axis; a plurality of tooth structures having first ends thereof which are configured to be received in the plurality of slots, second opposite ends and a central portion extending between the first and second opposite ends, said first ends each having a partial cylindrically shaped locating surface positioned and extending greater than 180° continuously to and between a pair of shoulder structures which shoulder structures resist angular deflection of the tooth structures when said first ends of said tooth structures are inserted in the plurality of slots, said partial cylindrically shaped locating surface having a constant uniform radius along an entire periphery thereof and a single radial center; and a plurality of coils which are configured to be received over the first ends of the plurality of tooth structures.
