Abstract: In one embodiment, a permanent magnet rotor is provided. The permanent magnet rotor includes a shaft comprising an outer diameter, a first hub coupled about the shaft outer diameter, and a first plurality of pole pieces positioned radially about the hub. The rotor further includes a plurality of permanent magnets positioned radially about the hub. The plurality of pole pieces and the plurality of permanent magnets define a rotor outer diameter, and the rotor outer diameter is magnetically isolated from shaft.

Abstract: A permanent magnet generator having the unique feature of a speed proportionally adjusted air gap for self-regulation of coil output voltage over a wide range of operating rotational speed of a steam turbine to which the invention is coupled. The Permanent Magnet Generator rotor is supported by the turbine end shaft and the stator is supported by a bracket bolted to the turbine pedestal base or other rigid structure. The speed proportional air gap is accomplished through the use of a plurality of centrifugal flyweights in mechanical coupling to a spool piece under spring load and to corresponding rare earth magnets via linkage such that increasing rotor speed extends the flyweights outward from the rotor center of rotation and draws the rare earth magnets closer to the rotor center of rotation and thus increases the air gap.

Abstract: A wind jet turbine with a housing that creates an air density deferential between the air within the housing and the wind passing outside the housing in order to generate the same or more electrical power in less space than traditional wind turbines.

Abstract: Overspeed protection of sensorless electric drives is needed in the aerospace industry. Methods for overspeed protection may include software implementations, hardware implementations or combinations thereof. Typical high-speed rotating machinery is designed to sustain overspeed operation of up to 50% beyond maximum normal operation. This requirement leads to substantial penalties in weight and volume. The methods of the present invention may allow for an opportunity to reduce this overspeed design to about 5 to 15%, typically about 7%.

Abstract: A fixed frequency electrical generation system includes an induction coupler. The system includes an electricity generator with no rings or brushes, and an induction speed regulator, mechanically coupled, so as to transform mechanical energy input from a shaft rotating at a variable speed into output electricity in the form of at least one alternating voltage with a constant rms value and constant frequency.

Abstract: An alternator or synchronous generator, principally for supplying electrical current to batteries and other apparatus in cars, ships, aeroplanes and other devices for transport. The alternator consists primarily of a hollow stator with windings of which the inner shell is conical, a rotor with a conical outer shell which operates in conjunction with the conical inner shell of the stator, a shaft which rotates in the housing of the alternator, a slide between the shaft and the rotor for the axial motion of the rotor over the shaft and in the stator for the purpose of current control, a device for sliding the rotor over the shaft into the stator, a device for sliding the rotor over the shaft out of the stator, and, on the rotating shaft a centrifugal voltage controller for fine-adjusting the means which slides the rotor out of the stator and keeps the induced current voltage the same.

Abstract: A generating apparatus for charging the battery of an automobile or the like is disclosed. A charging generator has an input shaft on which is mounted a driven pulley which is belt-driven by the drive pulley of an automobile engine. An adjustable speed change mechanism in the form of a planetary cone reduction gear is housed inside the driven pulley. The reduction gear transmits drive force from the driven pulley to the input shaft of the charging generator. A reduction ratio adjustment mechanism automatically decreases the ratio of the rotational speed of the input shaft to the rotational speed of the driven pulley as the rotational speed of the driven pulley increases so as to maintain the rotational speed of the input shaft substantially constant. In a preferred embodiment, the reduction ratio adjustment mechanism comprises a centrifugal governor.

Abstract: A pulse generator having a magnet or magnetizable mass mounted within a rotating disc to move radially as a function of angular velocity and gravity. A magnetic pick-up includes a magnet to attract the movable mass when it is aligned. Another magnet may be adjustably mounted on the disc to apply an adjustable radial magnetic force on a movable magnet.
