NOTES

  • All ThinGap machines can operate as a motor or generator and can be purchased with or without frame
  • When operated as a motor best performance is obtained with high frequency sinusoidal drives
  • 70μH per phase of external inductance is recommended when operated with conventional <40kHz drives
  • Contact ThinGap for drive compatibility and applications engineering
