Abstract
This paper concerns the unbalanced magnetic pull of a small non-salient pole synchronous motor caused by uneven magnetization of the rotor permanent magnet. The main task is to classify the rotor magnets according to polarization quality. The unbalanced magnetic pull consisting of the reluctance pull and the Lorentz force was selected as a suitable criterion assuming that a stator is perfectly symmetrical.
