The electrical machines with increased number of phases are being used in industry because of their reliableness, firmness, and safeness comparing with 3-phase induction machines and direct current machines. This paper compares the performance of a Five phase Induction Motor with different conduction modes such as 180°, 144°, 153°, and 171° in five phase voltage source Inverter. A comparison is made...

The paper presents the functional simulation model and performance analysis of permanent magnet synchronous motor (PMSM) drive. The control of PMSM is achieved using vector control technique which provides decoupled control of flux and torque. Using a proportional integral (PI) controller in the speed loop, a closed loop control scheme has been implemented and tested at different operating conditions...
This paper describes MATLAB/Simulink implementation of optimal excitation control on a three-phase induction motor (IM) for energy conservation at light loads. This simulation model is developed to support and enhance Loss Minimization Control (LMC) on electric machinery education at the undergraduate and postgraduate level in electrical engineering. This study provides the saving of real, reactive...
Based on the theory of the mathematical model of induction motor, the model of induction motor vector control is proposed with the simulation toolkit of Matlab/Simulink, and the related sub-system modules are described in detail and the specific illustrations of the sub-system are also given. Take a simulation of the system, the results such as the waveforms of the current, speed and so on could be...
The use of voltage source inverter (VSI) in high performance drives removes the restriction of the number of motor phases. Due to the reported advantages of multi-phase machines they have become of increasing interest to the industry. This paper provides a Matlab/Simulink built n-phase machine model in terms of physical variables along with the VSI and V/f control scheme that a user can easily set...
Small displacement equations valid for small excursions about an operating point are established from the machine equations expressed in synchronously rotating reference frame. The conventional form of d-q model used for drive simulation has limitations in predicting the machine performance. It is possible that, accurate results for fundamental component of current and average torque near rated operating...
BLDC motors have been gaining attention from various industrial and household appliance manufacturers, because of its high efficiency, high power density and low maintenance cost. After many research and developments in the fields of magnetic materials and power electronics, their applications to electric drives have increased to a significant extent. In this paper, the modeling of Brushless DC motor...
