This paper proposes a novel analytical method to calculate the maximum mechanical stress (MMS) on the rotor of the interior permanent-magnet synchronous motor with V-shaped rotor structure. Based on the traditional equivalent ring method, an improved method, which draws on the principle of equivalent centroid, is proposed to calculate the mechanical stress on the bilateral magnetic bridge. A rotor model with spokes is also built to calculate the mechanical stress on the central magnetic bridge… CONTINUE READING
