Abstract
A rotor for a synchronous motor includes a permanent ring magnet which has an inner surface, and a hub which has an outer surface. The hub is provided with a rotor shaft. Each surface is formed with a plurality of teeth. The teeth formed on one surface are shaped so as to be able to engage the teeth formed on the other surface. The engaged teeth form a force-locking connection between the ring magnet and the hub, when the hub is pressed into the ring magnet.
