R&D on Sensorless Control Technology for Brushless DC Motor Brushless DC motor with permanent magnet excitation, in which electrical commutator is used instead of mechanical, has the same good characteristics of speed control as traditional DC motor. Brushless DC motors have found wide application due to their high power density and ease of control. Moreover, the machines have high efficiency over wide speed range.
