ABSTRACT:
The invention relates to a reluctance motor having a ferromagnetic stationary member (3) and a ferromagnetic member (5) which is movable relative thereto, which exhibit an air gap (4) between spaced-apart pole faces (3c, 5c) of salient pole parts (3b, 5b), one of the members being provided with excitation coils, which surround ferromagnetic cores (3a, 5a) providing a ferromagnetic coupling between the pole parts of this member, the ferromagnetic cores being dimensioned to have such cross-sections that during the magnetisation of these cores by the excitation current the cores are magnetically saturated at the same time as the salient pole parts.
