Design and control of multiphase induction motor

2011 IEEE International Electric Machines & Drives Conference (IEMDC), 2011
Many researchers have studied multiphase Induction motor drives and output of their research shows that output Torque of these motors is superior to that of normal three phase Induction motor. Limitations on the power level of semiconductor devices establish a barrier to the increase of converter ratings.

Performance Analysis of Multiphase Induction Motor Drive

2010 International Conference on Electrical and Control Engineering, 2010
This paper analyses the mathematic model of multiphase induction motor, and the magnetic motive force generated by the harmonic currents. Compared to three phase drives, the multiphase motor drives have the advantage of performances on dead-time effect, common mode voltage, technology of non-sinusoidal source fed and reliability.

Thermal Analysis of Asymmetric Winding Multiphase Motor

2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019
Multiphase motors have high reliability and good fault tolerance ability, and are widely used in electric drive systems such as electric vehicles, ships and aircrafts. In these systems, the peak power of the motor is high, but it works in the light load state for a long time.

Multiphase induction motors for integrated drives

9th International Conference on Electrical Machines and Drives, 1999
The aim of this paper is to investigate drives based on high phase number, inverter-fed induction motors. The drive presented in this paper departs from the traditional approach of marrying production three phase motors with voltage source inverters by seeking to exploit the freedoms arising from considering the motor and inverter as a combined unit ...

Multiphase permanent magnet synchronous motor PWM technology

2013 International Conference on Electrical Machines and Systems (ICEMS), 2013
Firstly, This paper studied several PWM technologies of multiphase motor's control system: the Maximum-vector SVPWM, the Multi-dimensional SVPWM and the Carrier-based multiphase PWM. Secondly, the principle and the implement method of these PWM technologies were given, and this paper also analyses the advantages and disadvantages of these technologies.

Multiphase Induction Motor Drives

IET Chennai 3rd International Conference on Sustainable Energy and Intelligent Systems (SEISCON 2012), 2012
Recent research articles mostly addressing towards multiphase inverter fed multiphase induction motors due to their redundant structure, and reliability with high fault tolerant capabilities. Benefits over the traditional three-phase motors are, by reducing the amplitude and increasing the frequency of torque pulsations, lowering the rotor harmonic ...

MAGNETIC FIELD OF HIGHTORQUE STEPPING MOTOR WITH MULTIPHASE SUPPLY

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 1995
In spite of our previous results, where we have investigated the simplified 2D model, we would like to present our results coming out from real motor geometry. We use the Finite Element Method to solve the magnetic field of real cross‐section of hightorque stepping motor. This point of view allows us to investigate the multiphase (2 phase) supply.

Adjustable-speed drives with multiphase motors

1997 IEEE International Electric Machines and Drives Conference Record, 2002
A new theory for multiphase motors which takes into account current harmonics and all space harmonics of the magnetomotive force (MMF) is presented. It is shown that a multiphase motor for an adjustable speed drive (ASD) should have a full pitch or nearly full pitch winding with nearly rectangular space distribution of the phase MMF. The results can be

Torque pulsations of multiphase inverter-fed ac motors

Proceedings of 14th International Power Electronics and Motion Control Conference EPE-PEMC 2010, 2010
Torque pulsations of different types of PWMs with multiphase inverter-fed ac motors are investigated. For different phase numbers expressions for the torque ripples and computation of their components are derived for all the investigated PWM methods.

Multiphase Induction Motor Control

2013
This chapter presents a new complex dynamic model of a multiphase induction motor considering an arbitrary number of stator and rotor phases and including the odd order harmonic injection. Starting from the machine equations, the indirect rotor field-oriented control (IRFOC) is extended to the multiphase general case.
