Analytical modeling study reveals impedance-based performance metrics in single-phase reluctance motors, highlighting simple design rules to reduce torque pulsations and improve stability.

Key Points

To establish and experimentally validate an extended two-axis impedance framework that explains synchronous performance and guides design improvements for single-phase reluctance motors.
Extended classical two-axis theory to incorporate the combined impedance effects of both stator and rotor circuits.
Conducted parameter variation analyses and evaluated theoretical models against empirical measurements from a commercially manufactured motor.
Derived analytical relationships governing synchronous torque pulsations, capacitor-run operation, and stability under variable-frequency supply conditions.
Demonstrated accurate alignment between the theoretical impedance-based model and operational measurements taken from the commercial machine.
Identified critical parameter modifications that enabled the development of an improved motor design with attenuated torque pulsations at synchronous speed.
Determined that operational stability under variable-frequency power directly maps onto polyphase supply dynamics.
