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. In certain instances, a first composite sleeve resides around the moveable member. In some instances, the first sleeve includes a primarily axially-oriented outer layer and a primarily circumferentially-oriented intermediate layer beneath the outer layer. In other instances, the intermediate layer of the first sleeve includes a plurality of discrete, non-overlapping circumferential bands of composite material. In some instances, a portion of the first sleeve can have a coefficient of thermal expansion that is substantially equal to the aggregate coefficient of thermal expansion of the moveable member. In certain instances, a second sleeve can be formed from a metal tape wrapped over the first sleeve.
