High speed motors rotating at speeds above 10,000 rpm are gaining more attention nowadays for various high performance applications. High efficiency and reliability are demanded by the applications like centrifugal compressors, pumps, machine tools, drills, aerospace etc. This paper presents novel design and analysis of a high speed axial flux permanent magnet motor for high speed, low power applications...
This paper proposes a four-phase mutually coupled switched reluctance machine (MCSRM) arrangement with single pulse current control strategy, targeting performance improvements of both the machine and the power converter. Previously published works on MCSRM have focused only on machine performance while neglecting the power converters. Designs and comparative studies have been carried out among conventional...
Permanent magnet track linear motor drives offer a cost-effective motion control solution in numerous industrial manufacturing processes, covering a wide range of material handling and conveyor applications. To further reduce the initial costs of a permanent magnet track linear motor drive system, discontinuous magnet tracks can be considered. However, in a discontinuous magnet track, the armature...
The concentrated winding is the common winding method used in the conventional permanent magnet flux reversal machines (FRPM). In this paper a distributed winding for FRPM as a generator is proposed. To investigate the advantages of the proposed machine a comparative analysis of both the distributed and the concentrated winding for FRPM is performed. The output voltage waveforms of both machines are...
Multiphase induction motor (MIM) drives are becoming popular for high-power applications because of fault tolerant capability and wide range speed-torque characteristics. Using pole-phase modulation (PPM) technique, it is able to give high-torque for faster acceleration as well as high speed during steady operation. To achieve both these features, the MIM drive requires higher number of stator slots...
