Condition monitoring is an important issue in the maintenance of electrical machines. In the last years many methods of fault detection were cited in literature. Most of the newly proposed advanced methods are for on-line and non-invasive monitoring. This means that the faults can be detected already in their incipient phase during the usual work of the monitored machines. The aims of this pape...

We have designed kits of flexibly configurable components that students use to quickly wind and construct dc motors, permanent-magnet (pm) machines, and induction motors. They can use these machines to verify design calculations, test their understanding of the machine operating principles, and to test power electronic drives that they also design and construct. In class, the properties of diff...

Induction machines play a important role in industry and there is a demand for their reliable and safe operation. Different failures occurs in induction machines gives excessive down times and generate large losses in term, and this motivates the condition monitoring of induction motors. The condition monitoring includes taking measurements on three phase induction motor when it is operating in...

In terms of torque capability, power factor and efficiency, synchronous reluctance machines with high-anisotropy rotors represent an alternative to conventional induction machines. In particular, they have very robust rotors and can therefore operate at constant power in a wider fieldweakening range. The paper discusses a comparison of the various machine concepts using an identical machine geo...

This paper investigates and compares the torque-generating capabilities electromagnetic performance of advanced non-overlapping winding induction machines (AIM), conventional (CIM), interior-permanent magnet (IPM) for electric vehicle (EV) applications. All investigated are designed based on specifications Toyota Prius 2010 IPM machine. The steady-state flux-weakening characteristics calculated...
