Although the concept of variable-speed drives, based on utilization of multiphase machines,
dates back to the late 1960s, it was not until the mid-to late 1990s that multiphase drives …

This paper introduces a new fault-tolerant operation method for a symmetrical six-phase
induction machine (6PIM) when one or several phases are lost. A general decoupled model …

In the last few years, interest in multiphase converter technology has increased due to the
benefits of using more than three phases in drive applications. Besides, multilevel converter …

Direct torque control is a variable-structure control strategy with simplicity, fast response, and
tolerance to motor parameter variation, which provides direct control of stator flux and …

Industrial applications often require a number of variable speed electric drives. In the
majority of cases, these multi-motor drive systems require independent control of individual …

The interest in variable-speed multiphase induction-motor drives has substantially increased
in recent years and novel proposals show good prospects for industrial implementation in …

A technique to improve the flux pattern within a five-phase induction machine is presented.
The technique is developed through dual-plane vector control, with synchronized fluxes. By …

Multiphase variable-speed drives, supplied from two-level voltage-source inverters (VSIs),
are nowadays considered for various industrial applications. Depending on the drive …

The performance of a five-phase permanent-magnet (PM) motor is analyzed under postfault
conditions. Proper current control strategies are adopted so as to guarantee safe drive …

Multilevel multiphase technology combines the benefits of multilevel converters and
multiphase machines. Nevertheless, new modulation techniques must be developed to take …
