Permanent Magnet Motors & Generators

Permanent Magnet GeneratorsBarber-Nichols has designed and built over 50 different models of permanent magnet motors, generators, and motor/generators. The majority of these motors and generators were design specifically for use in Barber-Nichols turbomachinery. These span a variety of industries: automotive, industrial, military, energy, aviation, and space. 

A partial list of attributes of these magnetic machines:

  • Cooling Methods-Air, liquid, cryogenic gas from gaseous/liquid hydrogen to warm oil/gas
  • Shaft Speeds: 100 RPM to 200,000 RPM
  • Shaft Power: 1 Watt to 400 kW
  • Bearing Technology: hydrodynamic, foil, and ball bearings
  • Semi-Hermetic and Hermetic designs to isolate the stator from the process fluid
  • 2, 4, 6, and 8 Pole designs
  • Sinusoidal and Trapezoidal EMF windings
  • Designed use with commercial or Barber-Nichols custom controllers
