This work mainly focuses on Matlab Simulink model for electronic commutation of BLDC motor and co simulation of the model by using Xilinx System generator tool. The BLDC motors (AKM21E) are available in small size with good speed/torque characteristics. Since, the efficiency and dynamic response is high compared to brushed DC motor, they have widely used in various applications. We are using BL...

Switched Reluctance (SR) motors have a wide range of applications in industries, mainly due to the special properties of this motor. But, because of its dynamical nonlinearities, its control is complex. This paper presents an adaptive intelligent control based on the Lyapunov stability theory to control the speed of SR motors with good accuracies and performances. The proposed controller compos...

Induction motor drives using field oriented control (FOC) for torque and flux control have been used in high performance industrial applications instead of dc motors for many years. In FOC, torque and flux of an induction motor can be controlled independently by decoupling the stator current into its orthogonal components. The FOC method has achieved a quick torque response. But in order to ach...

This paper presents a novel five-phase permanent magnet synchronous motor (PMSM), which contains dual rotors and a single stator, equivalent to two five-phase motors working together. Thus, this kind of motor has the potential of good fault tolerant capability and high torque density, which makes it appropriate for use in electric vehicles. In view of the different connection types, the inside ...

This paper examines the proper application of three phase induction motors when supplied by unbalanced voltage. To analyze the effects of unbalanced voltage on torque of the induction motors, it has defined 32 unbalanced points, with 8 different types of voltage unbalance, and four levels of Voltage Unbalanced Factor, measured with Symmetrical Components method. In each unbalanced point the Tor...

The aim of this paper is to optimize the design of multiple flux barriers Synchronous reluctance motor in order to smooth the torque profile without rotor skewing. A new strategy is proposed by modelling the particular optimal design problem as mixed integer constrained minimization of a suitable objective function. The procedure has allowed to optimize the rotor shape for minimum torque ripple...

In recent years, the areas of industrial application of AC drives, especially Induction machine based on DTC technique has gradually increased due to its advantages over the other techniques of control. In conventional direct torque control, the selection of flux linkage & electromagnetic torque errors are made within the respective flux and torque hysteresis bands in order to obtain fast torqu...

Switched reluctance motor (SRM) drive has remarkable characteristics that make it attractive for high-speed applications. As the motor's speed increases the shape of the current waveform changes in such way that limits the production of motoring torque. At high speeds, it is possible for the phase current never reaches the desired value due to the self e.m.f. of the motor, therefore, the torque...
