What is BL Brushless Motor?

A conventional brushed motor is made up of carbon brushes, a ring of magnets (stator), an armature, and a commutator. When the motor is energized, a charge travels from the battery, through the brushes, into the commutator, and into the windings of armature. Then the magnetized armature starts to rotate. However, the magnets of Makita BL Brushless Motor are on the conventional motor shaft and the copper windings are fixed and surround the shaft. A small circuit board coordinates the energy delivery to the windings and controls the rotation of motor shaft. Therefore, carbon brushes and commutator are not required for brushless motor.
