This paper provides computer analysis and experiential investigation of the permanent magnet machines with neodymium ferrite magnets to discuss feasibility utilizing induction machines-oriented equipment for PM machine production. For this purpose, are obtained by replacing squirrel-cage rotor motor flux-focusing (tangential) surface-mounted (radial) rotors. Electromechanical parameters as elec...

The squirrel-cage induction motor remains the workhorse of the petrochemical industry because of its versatility and ruggedness. However, it has its limitations, which if exceeded will cause premature failure of the stator, rotor, bearings or shaft. This paper is the final abridgement and update of six previous papers for the Petroleum and Chemical Industry Committee of the IEEE Industry Applic...

The impact of fixed speed squirrel cage type as well as variable speed doubly fed induction generators (DFIG) on dynamic performance of a multimachine power system has been investigated. Detailed models of the various components have been presented and the integration of asynchronous and synchronous generators has been carried out through a rotor angle based transform. Simulation studies carrie...

As a new type of magnetic transmission structure, asynchronous permanent magnet coupling has wide prospect application in mechanical field. This paper proposes squirrel cage combined with structural characteristics motor and motor. In order to study its field model characteristics, according nonlinear field, separate analytical iterative method is proposed decompose air gap on one hand, as sour...

The use of multiphase electric drives in industrial applications has increased the last few years. These machines’ advantages over three-phase system make them appropriate for harsh working situations. To increase their inherent reliability, some authors have been sensorless control schemes, where absence an encoder ensures proper performance. Nevertheless, these systems present problems due to...

Abstract: Thin-walled integrated flexible support structures are the major trend in the development of current rolling bearing technology. A thin-walled, integrated, squirrel-cage flexible support roller bearing, quasi-dynamic iterative finite element analysis (FEA) model is established in this paper. The FEA model is used to calculate the structural deformation of the thin-wall rings and suppo...
