High performance and efficiency
BLDC motors are more efficient than their brushed motors, it can control the torque always maintain the maximum, but the brush motor only be maintained for a moment, not always in the maximum.
Durability and Low noise
BLDC motors operate more quietly because they don't have brushes that constantly make contact with other components. For brushed motors, the contact part will generate , sparks and noise, when the gap of the commutator meets the brushe.
Good heat dissipation
Their lower rotor inertia and their better dissipation of heat losses, which are particularly suitable for high speeds.
