Brushless DC Motors

Quiet Efficiency

Brushless DC (BLDC) Motors are mechanicaly simpler than brushed motors. They replace the brushes and associated sparks and noise with electronic commutation to silently switch the current flow to drive the motor. These quiet motors can be found in computer fans and disk drives, as well as in quadcopters, electric vehicles and high-precision servomechanisms.

Applications:

  • Multicopters
  • Drones
  • Radio Control Vehicles
  • Disk Drives
  • Fans
  • Industrial Servos
  • Hybrid Vehicles
  • High-End Gearmotors

Advantages:

  • Quiet
  • Efficient

Limitations:

  • Controller - Some types of brushless motors require a separate controller for operation.
