• Symmetrical Four-Phase Induction Machine
• Vector Control
• Current Sensor
• Multiphase Drives

Increasing the phase number enables reduction of the power per inverter leg, improvement of efficiency, reduction in torque ripples and etc. However, increasing the phase number causes the need of more power electronic devices and peripheral equipments such as sensors. Furthermore, in vector control of induction machine for controlling the d-q current components, measuring all independent currents is needed. Therefore, in this paper, a novel and simple structure is proposed for vector control of four-phase induction machines with only two current sensors. Although, it is shown in this paper that zero sequence current components will be eliminated due to the proposed structure. The simulation and experimental results verify, the performance of proposed structure.
