A reluctance motor/generator apparatus capable of operation at high rates of revolu-tion and high energy densities with reduced cooling-related windage losses and without incurring thermal damage to motor/generator elements. The apparatus includes an electrical winding-free reluctance rotor having a plurality of windage controlling and heat dissipating divider or barrier elements (which are also referred-to as thermal elements in the descriptions) disposed at opposite ends and periodically along its axial length to definite a plurality of rotor cooling chamber areas. The divider or barrier elements are provided with cooling fluid limiting apertures selected in size to optimize a relationship between rotor cooling effectiveness and windage energy losses. The machine stator is provided with cooling fluid release apertures of predetermined position and size relationship with the rotor cooling chamber areas. Use of the disclosed apparatus in the aircraft dynamoelectric machine environment is also disclosed.
