The study investigates the influence of the lamination geometry on the building factor of stator magnetic cores, quantifying by experiments the influence of the punching and the annealing process. The research and the experimental activity are focused on small-fractional-power synchronous reluctance motors, where the effect of the punching process is expected to be very impacting, not only for the stator iron losses increase, but also because the current magnetizing component is dominant in the total input current.

Abstract

The study investigates the influence of the lamination geometry on the building factor of stator magnetic cores, quantifying by experiments the influence of the punching and the annealing process. The research and the experimental activity are focused on small-fractional-power synchronous reluctance motors, where the effect of the punching process is expected to be very impacting, not only for the stator iron losses increase, but also because the current magnetizing component is dominant in the total input current. However, the obtained results are particularly interesting for any fractional and low power electric machines, whose cores are built with punched or laser-cut laminations.
