Abstract
A system to provide power to a tool includes an electric motor that can operate at rotary speeds of at least 6,000 rpm, a variable speed drive electrically connected to the electric motor, and a step-up transformer electrically coupled to the electric motor and the variable speed drive, in which the variable speed drive can generate and transmit a drive signal to supply power to the electric motor when the electric motor is spaced apart from the variable speed drive by a distance of at least 100 meters, and the transformer can prevent capacitive leakage in the drive signal transmitted over the distance from the variable speed drive to the electric motor.
