A new squirrel-cage rotor structure induction motor (IM) that has a auxiliary permanent magnet (PM) rotor and improved cage-rotor structure is presented to enhance the inherent power factor of the IM, and a prototype motor is fabricated by modifying the rotor of a conventional three-phase four-pole squirrel-cage induction motor. The flux linkage, flux distribution, power factor, core loss and e...

There has always been doubt on the accuracy of 2D analysis of small electric machines. To investigate the validity of this doubt, in this present work a small uni-coil shaded-pole induction motor is analyzed in 2D and 3D and the results are compared. In order to maintain the paper size as compact, the analysis is limited to the air-gap flux density distribution, variation of the main winding in...

This paper deals with control to sensor less vector control of induction motor using Genetic algorithm approach. This study discusses a method to control the speed of three phase induction motor based on sensor less control using Genetic Algorithm approach. With this method it is expected to produce accurate steady state speed response for the motor parameters. The analysis is done with convent...

This paper introduces a topology for achieving the brushless operation of wound rotor vernier motor using single-phase additional winding on stator, specifically designed variable-speed applications e.g., washing machines. In proposed topology, stator consists two sets: four-pole three-phase main and an two-pole winding. On other hand, contains 44-pole field to generate effect, excitation induc...

The switched reluctance motor is a simple and robust machine, which has found application over a wide power and speed ranges in different shapes and geometries. This paper introduces a new configuration for a two phase unidirectional switched reluctance motor/field assisted generator. The proposed novel motor/generator consists of two magnetically independent stator and rotor sets (layers), whe...
