Abstract
A self-starting single-phase synchronous motor comprising a generally bell-shaped permanently magnetized rotor, a coil located inside the rotor and having a core which is connected at both ends to stator parts having distinct poles, one of the stator parts being located between the coil and rotor and the other stator part being located outside the rotor, the rotor being rotatably mounted on the shaft with defined friction, a resilient coupling element arranged between the rotor and shaft, and locking means acting on the rotor for determining the starting direction of rotation and located in front of the resilient coupling element on the power transmission path.
