Abstract: The aim of the invention is to provide an electric motor which has a high torque at low rotation speeds and a high power at high rotation speeds. The invention therefore proposes an electric motor with permanent-magnet excitation having a first active part (10), which is fitted with permanent magnets (11), and a second active part (10), which can be moved in relation to the first active part (10) by magnetic force of the permanent magnets (11). The electric motor also has a heating device (12) with which the magnetic field of at least one of the permanent magnets (11) can be weakened by heating the permanent magnets as a function of a speed of the first active part (10) in relation to the second active part (8).

Abstract: 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.

Abstract: 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.

Abstract: The aim of the invention is to create a combined linear-rotary drive that has a compact, simple, and inexpensive design. Said aim is achieved by a combined drive comprising a linear driving device (3) and a rotary driving device (11), at least one of the two driving devices being provided with a hybrid reluctance motor. It is particularly advantageous to embody both driving devices as hybrid reluctance motors such that the rotor (4) can be produced at a low cost without permanent magnets in addition to ensuring that the drive has a very compact design.
