Steady-State Performance of Reluctance Machines

Polyphase reluctance machine performance is analyzed by direct-and quadrature-axis components, by circle diagrams, and by machine admittance. Specific equations are deduced for pull-out out torque, maximum power factor, no-load current, and pull-out current. A method is given by which the entire motor performance may be calculated through knowledge of machine admittance. Comparisons are made between calculated and measured results.
