    摘要： Cogging forces of a cylindrical linear motor are reduced with a linear motor having a rotor with eight poles and a stator with 36 toroidal coils (optionally multiples of eighteen toroidal coils) inserted into slots (N1 to N36) (or a multiple of 36 slots). The toroidal coils extend in the circumferential direction of the stator, are of equal size, and are arranged axially one behind the other. All the terminals of the toroidal coils are located in an axially extending connector channel. The two terminals of each coil are connected according to a specific connection scheme.

    摘要： A cylindrical linear motor includes a cylindrical rotor, and a cylindrical stator arranged in coaxial relationship to the rotor. The stator has a plurality of annular coils which are arranged in coaxial relationship, and a ferromagnetic stator core which includes a plurality of individual laminations which are aligned radially or arranged in a star shape. This reduces a field displacement caused by eddy currents, as a result of which ultimately a time delay in the force buildup is also reduced.
