2 | Biased unitized motor alternator with stationary armature and field | US392102 | 1982-06-25 | US4567407A | 1986-01-28 | John W. Ecklin |
A unitized (single unit) motor and flux switch alternator having stationary field, armature and motor windings which provides a magnetic path for some of the motor input power to feed through and increase the alternating current (AC) generator output. A rotor formed from a material having a high magnetic permeability (solid or laminated soft steel) is controlled in speed by controlling the magnitude and timing of the pulsed direct current (DC) supplied to the motor windings which may be wound on the stationary legs or the rotor. The current flow in the motor windings can be controlled by a mechanical commutator if the motor windings are on the rotor or by a solid-state converter if the motor windings are on the legs in a manner normally associated with brushless DC motors. The DC windings of the flux switch alternator can be replaced by permanent magnets since the reversing field in the AC output windings are predominantly time stationary. | ||||||

8 | Submersible pump drive system | US3751192D | 1971-04-12 | US3751192A | 1973-08-07 | BOYD C |
A pump is coupled with a motor in a deep well to remove fluid of variable density. The downhole motor is energized from an electrical generator which produces substantially constant volts/hertz output energy. The generator has an input shaft to which a constant torque is applied from a variable drive unit. As the fluid becomes lighter, the downhole motor speeds up and the generator produces an increase in both frequency and voltage amplitude to maintain system efficiency.
