Kearfott designs and produces an array of electric motors for use in the aerospace, defense and critical applications. Kearfott specializes in high performance permanent magnet (PM) and induction motors, our PM motors employ rare-earth permanent magnet materials and high performance magnetic alloys. Kearfott engineering’s optimized design techniques provide high power density while maintaining very competitive cost.

Kearfott also produces instrument grade induction and synchronous motors as well as VR and hybrid step motors.

Kearfott’s motor offerings include:

  • Brush DC
  • Brushless DC
  • Brushless pancake torquers
  • Induction
  • Reluctance
  • Synchronous
  • Stepper
