Transpermeance Amplifier Applied to Magnetic Bearings

  • Jossana Ferreira,
  • Eric Maslen and
  • Roger Fittro

15 February 2017

The most conventional approach of controlling magnetic forces in active magnetic bearings (AMBs) is through current feedback amplifiers: transconductance. This enables the operation of the AMB to be understood in terms of a relatively simple current-...
