Abstract:
A reluctance motor electric machine, comprising a stator (200) with a yoke body (210) forming a field body and stator pole teeth (201, 202) extending radially inward from the field body, with excitation coils (211, 212) associated with the stator pole teeth (201, 202), a rotor (300), which is supported so that the rotor rotates around a rotor axis (310) and has rotor pole teeth (301) directed radially outward that are spaced apart from one another at uniform angular intervals, a number and alignment of the stator pole teeth (201, 202) is chosen so that in rotational positions of the rotor that have minimal reluctance, by forming three pairs of pole teeth, wherein said three pairs including, three rotor pole teeth (301) are aligned in relation to three stator pole teeth (201, 202), and at least one of the stator pole teeth (201, 202) that does not belong to said three pairs is disposed between two neighboring pairs of said three pairs of rotor pole teeth (301) and stator pole teeth (201, 202), wherein said stator pole teeth and said rotor pole teeth of said three pairs respectively are disposed opposite each other, with air gaps between them.
