Brushless DC motors
Brushless DC motors offer several advantages over brushed DC motors:
- High torque to weight ratio
- More torque per watt (increased efficiency)
- Increased reliability
- Reduced noise
- Longer lifetime (no brush and commutator erosion)
- Elimination of ionizing sparks from the commutator
- Reduction of electromagnetic interference (EMI)

BLDC motor technology offers longer lifetime due to the absence of brushes and commutator erosion
With no windings on the rotor, they are not subjected to centrifugal forces, and because the windings are supported by the housing, they can be cooled by conduction, requiring no airflow inside the motor for cooling. This in turn means that the motor's internals can be entirely enclosed and protected from dirt or other foreign matter.
