  • Brushless dc Motors in Medical Applications
    windings or phases, similar to a 3 ac motor. But without a sensor to detect the rotation angle of the permanent magnet in the rotor, it’s impossible to know which phases to energize with a given polarity. The most common technique starts by energizing two of the phases with a given polarity. Current
  • Reducing cogging torque in brushless motors
    Brushless dc motor windings are similar to the windings in a multiple-phase ac motor. But brushless motors also contain a permanent --magnet rotor and a sensor to detect the rotor position to produce signals that control electronic switches for commutation. The most common position sensor
