Sigma-Delta modulation for multiphase drives
2009 35th Annual Conference of IEEE Industrial Electronics, 2009Sigma-Delta Modulation (SDM) technique, well known in the telecommunication industry, has recently shown its feasibility in conventional three phase power converters. In this paper, the SDM method is extended for the voltage modulation of multiphase power converters.

Variable-speed AC drives are nowadays based on three-phase electrical machines fed by power electronic converters acting as power interface between the electrical machine and AC or DC power sources. Nevertheless, in the last two decades the multiphase electrical drives have become an interesting alternative for particular applications.

Multiphase Induction Motor Drives
IET Chennai 3rd International Conference on Sustainable Energy and Intelligent Systems (SEISCON 2012), 2012Recent 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 ...

Multiphase hybrid traction drives for electrical vehicles
2014 International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2014The prospects for the use of multiphase (i.e. having the number of phases more than four) asynchronous linear and non-linear drives in the field of vehicles were presented and described in a number of papers. However the increase of the phase number of asynchronous electric drive system allows not only to improve a number of its technical-and-economic ...

Multiphase Permanent Magnet Motor Drive System Based on A Novel Multiphase SVPWM
2006 CES/IEEE 5th International Power Electronics and Motion Control Conference, 2006Multiphase motor drives are multi-dimensional systems, so multiphase vector control and SVPWM must be implemented in a multi-dimensional vector space. In this paper, multi-dimensional multiphase vector control is developed based on a novel multiphase SVPWM strategy, which could synthesize the required voltage vectors not only in d-q subspace but also ...

Multiphase induction motors for integrated drives
9th International Conference on Electrical Machines and Drives, 1999The 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 operation of switched reluctance motor drives
IAS '97. Conference Record of the 1997 IEEE Industry Applications Conference Thirty-Second IAS Annual Meeting, 2002Previous work on switched reluctance motors (SRMs) have dealt largely with singly excited phases. Where doubly excited phases have been used, either for torque production or position detection, the mutual coupling and effects of mutual saturation have been neglected. This paper demonstrates that these effects can produce erroneous results.

Liquid-Suspended Rotor Gyroscope Multiphase Driving Technology
Key Engineering Materials, 2013Liquid-suspended rotor micro-mechanical gyroscope uses a high-speed rotating hollow rotor in response to the density of the liquid as the mass to do the angular velocity detection. In order to improve the liquid-suspended gyroscope's performance, this paper suggested a new high performance magnetic driving technology.

Adjustable-speed drives with multiphase motors
1997 IEEE International Electric Machines and Drives Conference Record, 2002A 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

Performance Analysis of Multiphase Induction Motor Drive
2010 International Conference on Electrical and Control Engineering, 2010This 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.
