ABSTRACT:
A rotor for a two-pole synchronous reluctance or a switched reluctance motor can be constructed from a stack of flat, planar laminations of grain-oriented materials. To enhance the necessary anisotropy of reluctance, slots are provided in the lamination along the magnetic flux lines in the preferred grain direction. The laminations may be provided with an essentially circular outer perimeter, and slots for a squirrel cage winding provided. A complete, efficient squirrel cage winding can thus be provided for a two-pole synchronous reluctance motor for starting purposes.
