ABSTRACT:
An electric machine system includes an electric machine and a companion device. The electric machine has a stationary member and a movable member that, by interaction of magnetic fields, at least one of moves relative to the stationary member or generates electricity when moved relative to the stationary member. One of the stationary member and the movable member includes a permanent magnet. The companion device is coupled to the electric machine to communicate mechanical movement with the movable member. In certain instances, the electric machine system has adaptations for operation of the electric machine system subsea and/or in a corrosive environment.
