Rotor for synchronous motor, has permanent magnets slid into parallel pockets and made from punched metal sheets, where magnets are clamped in pockets in force-fit manner by shape of window edges
The rotor (1) has permanent magnets slid into parallel pockets (4) and made from punched metal sheets (2). Windows (3) are punched into the metal sheets, where the windows align with overlapping sheets together to form the parallel pockets. The magnets are clamped in the pockets in a force-fit manner by the shape of the window edges. Clamping metal sheets are arranged between the metal sheets and comprise tongue-like projections that bend and provide a clamping grip when the magnets slid into the pockets.
