Overview

Each time that motor electromagnetic vibration and loss is evaluated, it is also important to account for harmonic current form the PWM carrier. In JMAG, there are many ways of running magnetic field analyses that account for control circuits.

  • Stand-alone FEA analysis accounting for control
  • FEA and circuit simulator direct coupled analysis
  • Running circuit simulations using plant models (JMAG-RT model), and magnetic field analyses with obtained current waveform as input

This document explains how to use harmonic current waveforms in magnetic field analyses when obtained from running circuit simulation using plant models (JMAG-RT models).
