induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. speed identification is needed for the induction motor drives. however, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. ther...

Abstract Knowledge of steady-state processes of induction motors is critical in the understanding of their operating principle. In addition to the vast, systematic theories in literature, computer simulations provide a keen insight to the mechanism. Suitable modeling methods enable motors to be simulated with various parameters. Many phenomena can be predicted without hardware experimentation. ...

An electric drive is an industrial system which performs the conversion of electrical energy to mechanical energy (in motoring) or vice versa (in generator braking) for running various processes such as: production plants, transportation of people or goods, home appliances, pumps, air compressors, computer disc drives, robots, music or image players etc. About 50% of electrical energy produced ...

Cylindrical roller bearings used in traction motors for railway vehicles are at high rotational speeds and under light loads. Under these operating conditions, the life due to cage wear is much shorter than raceway fatigue. Therefore, bearing can be extended by reducing wear. The authors thought that reduce wear, it necessary establish a dynamic analysis method contact between cage, identify mo...

In this paper, a review on condition monitoring of induction motors is first presented. Then, an ensemble of hybrid intelligent models that is useful for condition monitoring of induction motors is proposed. The review covers two parts, i.e., (i) a total of nine commonly used condition monitoring methods of induction motors; and (ii) intelligent learning models for condition monitoring of induc...

Induction motors are the widely used motors in largely power-driven home appliances, agricultural and industrial applications. Induction motors are largely used because of its advantages such as Simple and rugged design, low cost, low maintenance and direct connection to an AC power source. Many applications need variable speed operation and one of them is a simple fan load. The main aim of the...
