Abstract
A method and apparatus relates to incorporating a magnetic coupling for use in oilfield applications. The magnetic coupling is operatively coupled to an oilfield machine to provide a controlled operational speed. The magnetic coupling may be operatively connected to a motor and a drive shaft where a speed of rotation of the drive shaft is controlled by an operation of the magnetic coupling. The drive shaft is operatively connected to the oilfield machine.
