Brushless Motors

摘要

THE IMPACT OF BRUSHLESS DC MOTORS for battery-powered hand toots is often compared to the lithium-ion battery revolution. Together, these two technologies have changed cordless tools used by electricians and those in other trades. Brushless design eliminates brushes and commutators while a circuit board coordinates the electronic energy within the motor. The result is a brushless-motor-powered tool that is more efficient and durable than one powered by a conventional electric motor.
