Pulse motor

A pulse motor comprising a stator consisting of a core of magnetic plates activated by a coil, an upper part of said motor containing a semi-cylindrical cavity in which a cylindrical rotor is suspended on each end by a shaft, said stator, said coil, and said rotor being located in a chassis split into two halves which can be joined such that the outside of each of said semi-chassis has the end of the shaft of the rotor projecting from said semi-chassis, said ends of said shaft terminating in a conical shape, said ends being supported in rolling sleeves engaged in said semi-chassis, the inner diameter of said rolling sleeves being larger than the diameter of the shaft of the rotor and each conical end of the shaft of the rotor being connected by elastic means for the conversion of movement consisting of first and second disks, each of said disks having a smooth face and a face with a centered cylindrical projection, said first disk located toward the interior of the motor having a conical bore adapted to receive the corresponding conical end of the shaft of the rotor, and said second disk located toward the outside of the motor and having a projecting semi-shaft of the motor, and a third disk being interposed between said disks consisting of an elastically deformable material, said third disk being adhered to the smooth sides of said first and second disks, said means for the conversion of movement being hidden in frames that may be solidly connected to each semi-chassis and adapted to receive, in the end opposite the one attached to the semichassis, cylinder heads including bearing means for said projecting semi-shafts of the motor, said bearing means presenting, in relation to said rotor of said motor and to said shaft, an eccentricity that is larger than the difference of diameters that exists between said shaft of said rotor and the inside of said rolling sleeves, in such a way that said shaft of said rotor is constantly forced into contact with the inner surface of said rolling sleeves.
