Research of Six-Phase Induction Motor Windings

open access: yesElektronika ir Elektrotechnika, 2014
Advantages of multi-phase motors raise interest in its construction. The article deals with elaboration of schemes of six-phase induction motor winding, calculation and analysis of magnetomotive forces and comparison of two type six phase motor windings: concentrated double layer full pitch coil six-phase winding and short pitch coil six-phase winding.

A Harmonic Suppression SVPWM Strategy for the Asymmetric Six-Phase Motor Fed by Two-Level Six-Phase VSI Operating in the Overmodulation Region

open access: yesEnergies, 2022
For the asymmetric six-phase motor fed by a two-level six-phase voltage source inverter (VSI), when the modulation index is less than 0.5774, the motor operates in the linear region, and the harmonics in the Z1 − Z2 subspace can be suppressed to zero ...

Asymmetrical Six-Phase Space Vector Pwm Scheme

open access: yesMokslas: Lietuvos Ateitis, 2014
Multiphase electric motors have smaller torque pulsations and are more reliable that their three-phase alternatives. However, standard electricity grids around the world are three-phase, so power inverter is needed to drive multiphase motors. Inverter is

SIX-PHASE LINEAR SWITCHED RELUCTANCE MOTOR DRIVE FOR ELEVATOR [PDF]

open access: yesمجله مدل سازی در مهندسی, 2014
In this paper, a six-phase switched reluctance motor for applications such as vertical transportation in a linear elevator is considered. The driving force ripple in a linear switched reluctance is high and the use of these machines in low speeds are ...

A Common-Mode Voltage Suppression Strategy Based on Double Zero-Sequence Injection PWM for Two-Level Six-Phase VSIs

open access: yesEnergies, 2022
A common-mode voltage (CMV) suppression strategy, namely double zero-sequence injection common-mode voltage (DZICMV), is proposed in this paper for an asymmetrical six-phase induction motor fed by two-level dual three-phase voltage source inverters (VSIs)

Reconceptualizing medication adherence: six phases of dynamic adherence

open access: yesEuropean Psychiatry, 2011
IntroductionNonadherence is the Achilles heel of effective psychiatric treatment. The meaning of the term “adherence” has evolved over time and is now associated with a variety of definitions and measurement methods. This has resulted in a poorly operationalized and non-standardized term that is often interpreted differently by providers and patients ...

Six phase rectifier digital computer simulation [PDF]

open access: yes, 1975
A digital computer program has been developed for the simulation of a six-pulse converter with a resistance-inductance load. The program calculates the time histories of the voltages and currents on both the ac and dc sides of the rectifier bridges.

Modelling approaches for an asymmetrical six-phase machine [PDF]

open access: yes2016 IEEE 25th International Symposium on Industrial Electronics (ISIE), 2016
With currently available power electronic devices, the power range of a single three-phase power converter is limited well below the power ratings foreseen for remote offshore wind turbines. A solution is to use multiphase systems. By connecting each of the converters to one three-phase winding in the stator of the machine, a multiphase conversion ...
