Abstract
A dynamoelectric machine having a rotor constructed to facilitate position sensing and a stator constructed to retain slot liners in the stator while reducing flux leakage between adjacent teeth of the stator. The rotor includes permanent magnets which project beyond one axial end of the rotor and the stator. Thus, a position sensor may be positioned in registration with the overhanging portion of the magnet. Slots in the stator are shaped to hold an insulating slot liner in the slot, and prevent the liner from slipping into the stator bore. The slots are also angularly formed near their inner ends to increase the space between adjacent stator teeth for reducing the flux leakage between the teeth.
