The paper deals with the features of analysis of magnetic part of the simplest construction of inductive electrical machines. Theanalysed machines have one or two sources of magnetomotive force (mmf). Synchronous oscillating machines and motors of oneimpulse of movement have such the simplest structure. Usually magnetic part of machine is analysed by calculating magnetic field bythe method of finite elements, by forming magnetic circuits of lumped parameters elements and their equivalent schemes with minimalnumber of elements. It is analysed the samples of linear motor with one mmf and non-salient poles motor with two mmf, which illustratehow indicated methods of analysis can to supplement each other (for instance, by setting the parameters of equivalent schemes). It isexpedient to mark out the permeances, which depend on the state of mechanical part, since the conversion of energy takes place in thesepermeances. The described method of analysis may be applied for machines with different complexity of their construction, for bothspecial and conventional inductive electrical machines.
