Abstract
A wedge-shaped member to restrain coil windings of a generator rotor from moving under centrifugal force. The wedge-shaped, substantially hollow member including a first plate, a second plate positioned opposite the first plate and positioned at an angle relative to the first plate, and one or more reinforcing members coupled between the first plate and the second plate. The wedge-shaped member is configured to fit between the core poles of a generator. A plurality of holes in the first and/or second plates permit a bonding material to adhere to adjacent coil windings and spread through the holes.
