ABSTRACT:
A guide frame for an eddy current type braking system includes a brake drum connected to a rotary shaft; a stationary pole piece frame formed of a non-magnetic material, disposed within the brake drum and retaining a plurality of ferromagnetic plates opposed to an inner surface of the brake drum; and magnet support rings formed of a magnetic material and retaining permanent magnets opposed to the ferromagnetic plates. An outer surface and an inner peripheral surface of each ferromagnetic plate is displaced in a direction parallel to the axis of the brake drum, and an axial center of the outer peripheral surface of the ferromagnetic plates is substantially radially aligned with an axial center of the brake drum.
