Finite element torque calculation in electrical machines while considering the movement

Inductance and Torque Calculation of Permanent Magnet Synchronous Machines using the Frozen Permeabilities Method with the Finite Element Analyses

Permanent magnet synchronous machines with fractional slot stator windings using the tooth coil technology require detailed investigations on the electromagnetic parameters due to a very low number of slots per pole and phase. Finite element analyses can provide many results but a subsequent application of the frozen permeabilities method allows for a more detailed discussion of effects caused ...

Electrical and Thermal Analysis of Single Conductor Power Cable Considering the Lead Sheath Effect Based on Finite Element Method

This paper investigates the effect of metallic sheaths on losses and temperature of medium voltage power cables. Two grounding methods of sheaths, including both ends bonding and single point bonding that causes different situations on cable ampacity, are considered. Electrical losses of cables that are main sources of heat are calculated in both conductor and metallic sheath of the cables. She...

Calculation of Local Iron Loss in Electrical Machines Using Finite Elements Method

Calculations of iron losses in the electrical machines are normally based on experimental characteristics of core material used in the machines. These methods with simplified machine analysis approximations are usually employed for calculation of total iron losses of electrical machines whilst local flux densities and corresponding local iron losses especially when designing of the machine and ...

Calculation of Slot Losses in High Frequency Electrical Machines

-As new magnetic materials as well as applications emerge in electromechanical conversion systems, one finds that electrical machines are increasingly moving away from the mainstream power frequency to much higher frequencies. This shift is mostly being driven by the fact that for the same power a higher speed machine is smaller in size. Operating at higher frequencies has its advantages on siz...
