Simulation of a new multiphase BLDC motor drive

2012 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2012
In this paper, a new model of 9-phase BLDC motor drive is studied and the model will be implemented using Matlab/Simulink software. The motor has been simulated through dynamic modeling and using the switching functions concept. In addition, in order to create constant torque and take advantage of the maximum torque capacity of motor, hysteresis ...

Multiphase Flow and Heat Transfer in an Electric Motor

Volume 8: Fluids Engineering; Heat Transfer and Thermal Engineering, 2022
Abstract Electric vehicles are becoming increasingly common due to environmental needs. Due to this, efficiency in design process of electric motors (E-motor) is becoming critical in the industry. To assess performance capabilities for an E-motor, thermal predictions are of utmost consequence.

Experimental investigation of multiphase transformer fed induction motor

2016 IEEE Region 10 Conference (TENCON), 2016
The production of multiphase system was a challenging task in earlier days, multiphase means more than three phases and very much popular now a days due to eminent features compared to conventional three-phase counter parts. In order to obtain the multiphase machine, it requires same phase input with respect to the no. of phases at the output.

Operation of the multiphase induction motor

1998
A notable feature of induction motors, including polyphase motors, is their very simple construction, which illustrates two dismantled 3-phase induction motors. Their being relatively inexpensive and needing little maintenance as well as their being operable directly from the 3-phase mains supply without needing intermediate circuitry has led to the ...

Advanced sensorless drive technique for multiphase BLDC motors

30th Annual Conference of IEEE Industrial Electronics Society, 2004. IECON 2004, 2005
The main purpose of this paper is to develop a new position sensorless drive method for multiphase brushless DC (BLDC) motors. A BLDC motor with higher number of phases has several advantages. It can reduce the ampere-turns and torque pulsation and increase the efficiency and iron utilization.

Multiphase induction motors for a variable speed drive

Proceedings of the 9th International Scientific and Practical Conference of Students, Post-graduates Modern Techniques and Technologies, 2003. MTT 2003., 2005
The purpose of the present paper is selection of the most suitable multiphase induction motor for a variable speed drive. One can use induction motor with phase number more than three in a variable speed drive. The modern level of electronics development allows us to design the motor control system for the multiphase induction motor.

Off-line co-simulation of multiphase PM motor-drives

2016 XXII International Conference on Electrical Machines (ICEM), 2016
This paper refers to the dynamic simulation of multiphase permanent-magnet motor drives featuring independent-phases structure. Based on the co-simulation approach with a finite element analysis, a circuital model is developed in which the usual inductive parameters and back-EMF coefficient are replaced by current and rotor position dependent functions,

Control of Multiphase AC Motor Drives

2010
Three-phase AC motor has been used as the main driving machine for a very long period. The main reason for the use of three-phase machines has the availability of three-phase AC supply from the mains. However, with the availability of power electronic devices of high power rating, the control of drives is always from the inverter supplying power to the

FE analysis of multiphase doubly salient permanent magnet motors

IEEE Transactions on Magnetics, 2005
This paper presents the results of two-dimensional (2-D) finite-element analysis (FEA) carried out on 8/6 and 6/4 doubly salient permanent magnet (DSPM) motors to arrive at the magnet leakage factor and the flux density ratios of various parts of the motors so as to aid the designers of this newer motor. The two permanent magnets being kept embedded in

Rotor field oriented control strategy of multiphase induction motor

2011 IEEE 5th International Conference on Robotics, Automation and Mechatronics (RAM), 2011
Based on studying the transform theory of the multiphase system and the rotor field oriented control (RFOC) of multiphase induction motor (IM), the mathematical modulation of RFOC used in multiphase IM with closed-loops of harmonic currents is modeled.
