Abstract

The lamination stack is covered on both sides with cover plates with at least one area restricting the magnetic flux inside the plates, at the foot of a pole shank; the plate cross-section is reduced to a size only sufficient to hold the plate together; or the plate consists of separate elements, joined together by a more extensible material. The cover plates are of a square and squat 'U' shape. Where one piece cover plates with a narrow neck are used, the neck is at the base of the side arms of the 'U', either in the centre of the side arms, or towards the outside of the 'U'.
