Abstract
A rotor for a synchronous motor includes teeth arranged at regular intervals, project from a rotor core in the radial direction, and taper in a cross-section in the direction of the rotor core. The rotor also includes tangentially magnetized magnets that are arranged in gaps between the teeth and are trapezoidal in cross-section. The teeth are connected via a flexible joint to the rotor core, and the teeth are deflected in the tangential direction such that in every other gap between two teeth, first magnets rest against outer stops at the ends of the teeth facing away from the rotor core.
