Although, Single-Sided Linear Induction Motor (SLIM) utilization has increased in railway applications due to their numerous advantages in comparison to Rotational Induction Motors (RIM), there are some sophistication in their mathematical models and electrical drive. This paper focuses on the problems of SLIM modeling, with assuming end-effect on the basis of Field Oriented Control (FOC) as a ...

Hunting is a flutter associated with the synchronous speed that gives rise to the gyro drifting errors and may cause objectionable time-displacement errors in video head wheel drives and other precision scanning systems. In this paper, dynamic characteristics of permanent Magnet hysteresis motors are presented and hunting is explained. New damping techniques have been developed using optimi...

extension of inter-turn fault in windings of pmsm can damage all parts of electrical systems, and in some cases in sensitive applications may lead to irreparable events. identification of such small faults at incipient steps can be so helpful to protect entire part of electrical system. in this paper, intelligent protection system is designed which is made by two major parts. in the first part ...

The paper deals with real-time control of PM synchronous motor for sensorless position using Power PC-MPC processor. Real parametric-and real-time model could be ideal tools for both control and simulation of the PMSM (permanent magnet synchronous motor) position drive. Unfortunately that idealized model doesn’t exist so far. Such a model has to face following serious problems: it must be excit...

This paper investigates an optimization procedure for the design of a synchronous motor (SM) using a particle swarm optimization (PSO) procedure. The PSO is proposed to minimize the motor volume and to maximize the motor output power. The proposed procedure has two stages for motor design. In the first stage, the stator parameters are optimized while in the second stage, the field and damper wi...

In order to obtain the influence of different structures and frequencies on thrust cylindrical permanent magnet linear synchronous motor, transient simulation magnetic field motor is carried out by using Ansoft software, correctness verified experiments. Through simulation, characteristics under voltage frequency, air gap size, width its are obtained.

This paper describes the robust optimal incremental motion control of a current  sensorless synchronous reluctance motor (SynRM), which can be specified by any desired speed profile. The control scheme is a combination of conventional linear quadratic (LQ) feedback control method and sliding mode control (SMC). A novel sliding switching surface is employed first, that makes the states of the Sy...

This paper presents the detailed simulation of comparison between Induction Motor and Synchronous Motor with reduction of resonant frequency oscillations in their terminal voltages by using Active damping technique. This paper mainly concentrated on protection of Induction motor and Synchronous motor under any balanced or unbalanced load conditions and this proposed technique is simulated with ...
