Brushless DC Motors

Brushless DC motors are extremely desireably as they completely eliminate the need for brushes. This increases their life, survival without maintainance, power output and efficiency dramatically.

Their basic working principle is to facilitate an external commutator, which will reverse the direction of the current depending on the position of the rotor.

As there are no brushes, maintainence levels are lowered dramatically, and as there is no friction caused by brushes, the efficiency of a brushless motor is typically between 85 and 90 percent (a brushed motor's efficiency is usually about 75 to 80 %). This makes them ideal for heavy duty use, and cost efficiency in the long term. They also run much cooler than AC and brushed motors, which greatly increases the life of the motors in context.
