ABSTRACT:
A linear electric motor has an inner armature which is adapted to reciprocate axially and an outer stator which includes a plurality of axially extending laminations which have inner edges engaging each other and defining a cylindrical bore in which the armature is situated. These laminations respectively have axially extending outer edge regions which are oppositely inclined one with respect to the next with each lamination having an outer edge pressing against an outer edge of the next lamination and spaced from the outer edge of the preceding lamination, so that the outer edge regions of the laminations define between themselves axially extending spaces which alternately converge and diverge radially inwardly toward the common axis of the armature and stator.
