Abstract The authors consider several tens of rotor tooth and slot profiles for the inductor electric machine in order to gain the maximum EMF of the armature winding at the minimum of highest harmonics, owing to which the specific power and efficiency of the machine can be raised. The research considers usage of analytical methodology and finite element method (FEM), where the latter includes magnetic saturation and actual magnetic field line distribution. The main data of both calculations are summarised in the results of the study. From the obtained results, it can be concluded that, in most cases, the analytical method is not applicable to the qualitative determination of the highest harmonic content of the EMF, since the plane of the magnetic field lines does not close in parallel and their distribution is directly related to the configuration of the teeth zone. The possibility of using the inductor generators for direct connection to the grid is demonstrated in the study.
