Field Loss in Power Transformer (T.E.A.M. Problem 21)

Presented here is MagNet’s analysis of a power transfomer in which two exciting coils directed in opposite directions and shielded by magnetic steel plates. The simulated nonlinear eddy current and hysteresis losses are compared to measured results.

Field Loss in Power Transformer (T.E.A.M. Problem 21a)

Presented here is MagNet&r analysis of the second set of configurations from the family of benchmarks involving two exciting coils directed in opposite directions and shielded by a non-magnetic steel plate. The steel plate has four configurations; no slot, one slot, two slots and three slots. The eddy current losses are compared in all configurations to measured results.

Field Oriented Control of an IPM

Field oriented control of an interior permanent magnet machine is presented in this example. A 70 KW IPM designed using MotorSolve BLDC is used as an example here; a summary of the motor characteristics, the PI control scheme, the integrated system that includes the motor model and SIMULINK interface and results of some test simulations for controlloing the speed of the motor.

From Electromagnetic Forces to Acoustics Part 1

The electromagnetic forces computed by MagNet can be transferred by the FSIMapper to structural analyses. For transient MagNet results additionally a Fourier transformation can be applied in order to generate the loading for structural vibration analyses. In this way the engineer is able to investigate the resulting vibrations and noise emissions. Also partial MagNet models (with even or odd periodicity) are supported to be mapped on full structural models. The functionality is presented using some examples. (This was originally presented at Engage 2015).

Impact of Materials on Reducing Stray Losses (T.E.A.M. Problem 21b)

This examples involves three different configurations of plates: one magnetic and one non-magnetic plate, two magnetic plates and two non-magnetic plates. The flux density is measured along contours on the plates’ surface and compared with measured results.
