10	Electro-magnetic motor for timepiece	US969539	1978-12-14	US4262223A	1981-04-14	Willy Cleusix
An electro-magnetic motor for a timepiece wherein the stator is formed of two pole pieces contacting the ends of a core traversing a coil. Both ends of the core and one end of each pole piece have notched portions with cross sections of the notched portions of the core being at least equal to the cross section of core as it passes through the coil and cross sections of the notched portions of the pole pieces being substantially equal to the cross sections of the notched portions of the core, so that the notched portions do not produce an increase in the resistance to the passage of magnetic flux through the core and pole pieces.
11	Low power synchronous motor and line cord therefor	US610678	1975-09-05	US3988639A	1976-10-26	Ralph H. Preiser; Frank W. Stellwagen; Anthony W. Rigazio
A low power synchronous motor is disclosed having a rotor including a pair of rotor discs between which is sandwiched a permanent magnet which is polarized such that one of the rotor discs is a north pole and the other is a south pole. The stator includes an energizing winding having a core passing therethrough. A pair of complementary stator plates are secured at each end of the energizing winding to the core and are bent at right angles to form a copolanar stator air gap portion. The coplanar portion of the stator has a notched, circular air gap into which the rotor is positioned. The flat stator plates provide for easy assembly of the motor in a clock movement. The electrical energy coupled to the energizing winding is attenuated by means of a pair of impedance elements connected in series with the energizing winding and situated in the plug of the energizing circuit. The impedance elements reduce the current flow into the clock and hence prevent the possibility of a hazardous shock to someone coming in contact with an exposed wire.

13	Synchronous motor	US37402273	1973-06-27	US3869627A	1975-03-04	INGENITO MICHAEL J; CORSER PAUL J
A synchronous self-starting timer motor having a disc shaped rotor with an annular ring of permanently magnetized poles about the periphery thereof. The magnetized poles are of alternately opposite polarity with the magnetic fields generated thereby being substantially perpendicular to the plane of the rotor. The stator includes a core having at least one pole pair which defines an axial air gap through which the magnetized annular pole portion of the rotor passes. Proximate each pole of the stator is a protrusion which extends in a direction parallel to the plane of the rotor and which perturbs the magnetic field passing between the poles such that the motor becomes selfstarting when exited by an electrical current. The stator also has an energizing winding which induces an alternating or pulsating flux field in the core of the stator which field coacts with the field of the rotor to drive the rotor at a speed proportional to the frequency of the flux field. The rotor has a low moment of inertia, is light in weight and has a large magnetic working area so that the synchronous motor is capable of generating high torque at a low input power level.

17	Synchronous reluctance motor	US3576455D	1969-11-05	US3576455A	1971-04-27	INGENITO MICHAEL J
A synchronous reluctance motor particularly useful as a clock drive motor. The motor includes a stator having an airgap and a rotor having spaced teeth of magnetic material which travel in a circular path and pass through the airgap of the stator. A magnetic flux is established periodically in the stator airgap in timed relation to an approaching tooth. The timing is such that flux buildup in the airgap occurs when an approaching tooth is closer to the airgap than a receding tooth, and the flux is approximately zero when the tooth is at the center of the airgap. Hence, there is no retarding force on a tooth as it leaves the airgap. The pulsating flux is established, in one embodiment, by a power source which supplies periodic current pulses to the stator winding. In another embodiment, the power source has a sinusoidal wave form, and a magnetic shunt paralleling the stator airgap converts the sinusoid into a series of current pulses for energizing the stator winding.
