Permanent magnet synchronous motors (PMSM) and asynchronous induction motors (IM) are widely used in the industry for a diverse set of applications. Although the use of induction motors is increasing for industrial applications due to cost inconsistency in rare earth magnets, PMSM motors are still being used because of their compact size, high power density, and greater efficiency. In interior permanent magnet synchronous motor (IPMSM) and surface mounted permanent magnet synchronous motor (SPMSM), the non-oriented silicon steel core is in continuous contact with high-energy rare earth magnets. This paper focusses on the effects of these high-energy magnets on the magnetic properties of M-19 steel core. It is observed that the relative permeability of the M-19 steel decreases when it is kept in contact with three sintered Neodymium (NdFeB), grade N45 permanent magnets. This leads to decrease in the inductance of the motor. It thus depicts a very important concept which is generally ignored while designing motors especially for electric propulsion and industrial applications where the effects can be significant.

The Concepts of Sizing and Optimization Model: applied to the Optimal Design of a Permanent Magnet Generator Carlson, Renato; Wurtz, Frederic (2011-09-10) This paper is a methodological contribution in order to characterize two kinds of models that should be used in a complete optimization process of energy conversion systems like motors or actuators. We will indeed introduce the concept of "sizing model", and the concept of "optimization model". We will show also how to use them in a design process in order to produce optimal result that we concatenate in "an optimal design graph". All those methodological results will be illustrated on the optimal design of...
Comparison of Matrix Converter Induction Motor Drive Control Methods Lettl, Jiri; Kuzmanovic, Dragan; Fligl, Stanislav (2011-09-10) In this paper, the implementation of the Field Oriented Control and the Direct Torque Control in matrix converter supplied induction motor drives is analysed, and compared with the implementation in drives supplied by the Voltage Source Inverter. The analysis is accompanied by the results of numerical simulations and experimental implementations of these two control methods.
Modelling and Precalculation of Additional Losses of Inverter Fed Asynchronous Induction Machines for Traction Applications Muellner, F.; Neudorfer, H.; Schmidt, E. (2011-09-10) The inverter supply of asynchronous induction machines for traction applications has a major influence on both electromagnetic and thermal performance. In addition asynchronous induction machines used with traction drives of rail transportation vehicles have different design strategies compared against commonly used standard machines. Generally, the design of these machines requires high electromagnetic and thermal stress. Thus, the additional losses caused by the inverter have to be considered with the ini...
Calculation of core losses of a six-phase induction motor with third harmonic current injection Büyükbaş, Afşin; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004) The advantages of using a six-phase induction motor for industrial drives, over the conventional three-phase drive can be summarized as improved reliability, reduction on the power ratings for the static converters and harmonic reduction. A technique of injecting third harmonic zero sequence current components in the phase currents to improve the machine torque density was presented recently by another research study. However, to meaninigfully evaluate the performnce of such machines and/or to be able to ma...
Modeling of Multi Open Phase Fault Condition of Multi-phase Permanent Magnet Synchronous Motors Fei, Marco; Zanasi, Roberto (2011-09-10) This paper deals with the modeling of multi-phase permanent magnet synchronous motors under multi open phase fault condition. The presented model is suitable for generic number of phases, generic shape of the rotor flux and generic number of open circuit faults. The motor model in fault condition can be used for faults occurring on both adjacent and not adjacent phases. The model can be very useful both for simulation and implementation of fault-tolerant control strategies.
