In this paper, a rotor-flux-oriented control scheme for seven-phase induction motor drives is presented. At low speed the proposed control scheme is able to increase the motor torque by adding a third harmonic component to the air-gap magnetic field. Above the base speed the control system reduces the motor flux in such a way to ensure the maximum torque capability. The validity of the proposed control scheme is confirmed by experimental tests.

Abstract
In this paper, a rotor-flux-oriented control scheme for seven-phase induction motor drives is presented. At low speed the proposed control scheme is able to increase the motor torque by adding a third harmonic component to the air-gap magnetic field. Above the base speed the control system reduces the motor flux in such a way to ensure the maximum torque capability. The validity of the proposed control scheme is confirmed by experimental tests.File in questo prodotto:
