Vector Control of a Current Superimposition Variable Flux Reluctance Motor

We propose a current superimposition variable flux reluctance motor for a traction motor of hybrid electric vehicles. This motor has 2 sets of 3-phase coils, and 2 current control methods (single and twin vector controls) can be applied. However, any effective control methods have not seen. This paper discusses the current control method of the current superimposition variable flux reluctance motor. Single and twin vector controls are compared. The single vector control is effective for the current superimposition variable flux reluctance motor because even orders of the currents are removed by composing 2 phase currents. In addition, harmonic components of the phase current under single vector control contribute to increase a torque.
