Multi-phase motor drive system are increasingly used due to their inherent advantages. Several topologies are investigated in the literature for multi-phase drive system. The most popular among them are five-phase and six-phase. In six-phase system two topologies exist. In one topology, the windings or phases are 60 degrees apart and called symmetrical six-phase system. The second topology has two...
The first five-phase induction motor drive system was proposed in the late 1970s for adjustable speed drive applications. Since then, a considerable research effort has been in place to develop commercially feasible multiphase drive systems. Since the three-phase supply is available from the grid, there is a need to develop a static phase transformation system to obtain a multiphase supply from the...
This paper presents qualitative and quantitative approach to access torque pulsation in an open-loop inverter fed induction motor drive system. The inverter used to supply a three-phase induction motor operates in either 180° or in 150° conduction mode. A comparison in the performance of the drive system is presented for the two conduction modes. Analytical and simulation results are provided to support...
