What is Brushless DC (BLDC) Motor

A Brushless DC (BLDC) motor is a Permanent Magnet Synchronous Motor with unique back EMF waveform that allows them to behave similarly to a brushed DC motor. Some confusion can arise from the name, as a brushless DC motor does not directly operate off a DC voltage source. However, the basic principle of operation is similar to a DC motor.

A Brushless DC Motor has:

  • A rotor with permanent magnets and a stator with windings.
  • A BLDC motor is essentially a DC motor turned inside out .
  • Brushes and commutator have been eliminated and the windings are connected to the control electronics .
  • Control electronics replace the function of the commutator and energize the proper winding .
  • Windings are energized in a pattern which rotates around the stator .
  • The energized stator winding leads the rotor magnet and switches just as the rotor aligns with the stator .
