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.
Claims10
A self-starting single-phase synchronous motor comprising:
- a generally bell-shaped permanently magnetized rotor;
- a stator having two parts each with distinct poles;
- a coil located inwardly of the rotor and having a core which is connected at its end to said two stator parts, one said stator part being located between said coil and rotor and the other said stator part being located outwardly of said rotor, said rotor being rotatably mounted on a shaft with defined friction;
- a resilient coupling element interposed between said rotor and shaft, said resilient coupling element engaging said rotor and shaft for resiliently transmitting torque from said rotor to said shaft;
- and
- locking means mounted on said rotor and acting on said rotor for locking said rotor preventing rotation in an undesired direction and for permitting starting of said rotor in the opposite, desired direction of rotation, said locking means located in front of said resilient coupling element on the power transmission path.
