Abstract
The article considers the issue of ferromagnetic wedge application efficiency for the anchor and main pole slots in DC motors. Magnetic field simulation results using finite element method as exemplified by the commercial DC motor are provided. The findings obtained are analyzed for the cases with and without the ferromagnetic wedges. The change of the machine magnetic flux value is evaluated.
