A rotor for an electromagnetic apparatus including: ferromagnetic laminates stacked along a longitudinal axis of the rotor; non-magnetic laminates stacked along the longitudinal axis, wherein the non-magnetic laminates are between the ferromagnetic annular laminates; cavities in the rotor formed by aligned slots in the ferromagnetic and non-magnetic laminates, wherein the cavities are parallel to the axis of the rotor, and a permanent magnet(s) in each of the aligned cavities. The laminates may each be an annular disc or may be segments arranged in an annular array around a shaft of the rotor.

A method to start a combined unit gas turbine and electrical unit having a static start drive including the steps of: applying a variable frequency voltage from the static start drive to a winding of the generator to accelerate the combined unit to a turbine self-sustaining speed; accelerating the combined unit beyond the self-sustaining speed by applying torque generated by the turbine, and as the combined unit accelerates to a synchronous speed, applying a braking torque from the static start drive to steady the combined unit at the synchronous speed.
