Problems solved by technology
From the critical speed, the current in the winding cannot increase to normal value until the winding is de-energized again
This results in an unfavorable torque reduction, the motor starts skipping, and eventually stops

Embodiment Construction
[0076] figure 1 A perspective view of the reluctance motor of the present invention is shown. The reluctance motor has an annular closed armature 1 made of laminated steel. Arranged inside the annular armature 1 is a rotor 2 which is rotatably mounted in the annular armature 1 and which is also manufactured from laminated steel. The two coils 3 , 4 are wound onto the ring armature 1 opposite each other and extend along the circumference of the ring armature 1 , ie along the length of the armature 1 . The coils 3 , 4 are wound from copper and surrounded by a housing. Strictly speaking, in figure 1 Only the housing surrounding the coils 3, 4 can be seen.
[0077] The wire winding is wound around the ring surface of the ring armature 1 . The ring armature 1 may initially exist in two parts and may be joined to each other after the coils 3, 4 have been wound to form the "ring" shown.
[0078] A control unit 5 is used to control the voltage supply to the coils 3 , 4 . Two po...

Abstract
The invention relates to an electric motor, in particular a reluctance motor, comprising: an armature containing a magnetisable material, wherein the armature has a plurality of pole shoes; an actuator which is arranged and mounted movably with respect to the armature, contains a magnetisable material and has at least two magnetisable pole ends; and an even number of coils, which are arranged between the pole shoes and whose windings surround the armature in such a way that the coils extend regionally along the armature such that the armature is magnetisable with the aid of the coils. The invention also relates to a method for producing an electric motor, in particular a reluctance motor, in which an even number of coils is applied to an armature containing a magnetisable material, wherein the coils are arranged between a multiplicity of pole shoes, with the result that the windings of the coils surround the armature in such a way that the coils extend regionally along the armature, and an actuator containing a magnetisable material comprising at least two pole ends is mounted movably with respect to the armature. Finally, the invention also relates to the use of such an electric motor, in particular such a reluctance motor, for driving a movement of an apparatus or of part of an apparatus.
