摘要： Kinetic energy harvesting methods and devices are disclosed. A portable kinetic energy harvesting device includes a housing with a plurality of magnets fixed at spaced-apart locations in the housing. A wire coil is movably positioned in the housing for reciprocating movement past the magnets. The reciprocating movement of the wire coil through magnetic fields of the magnets generates an alternating current in the wire coil. A circuit electrically connected to the wire coil includes a rectifier to convert the alternating current generated by the wire coil into direct current. The device can be used to charge batteries including, e.g., batteries for powering portable electronic devices.

摘要： A system for wirelessly transmitting power between a track and independent movers in a motion control system includes a pick-up coil provided proximate to the magnets on the movers. The fundamental component of the voltage applied to the drive coils interacts primarily with the magnetic field generated by the permanent magnets on the movers and not with the pick-up coil. Consequently, the pick-up coil does not interfere with desired operation of the movers but rather, interacts primarily with the harmonic components and has current and voltages induced within the pick-up coil as a result of the harmonic components. The energy captured by the pick-up coil reduces the amplitude of eddy currents on the mover. After harvesting the harmonic content, the pick-up coil may be connected to another circuit on the mover and serve as a supply voltage for the other circuit.

摘要： A kinetic power generation unit (1,2,3) improves the magnetic field of an electric motor (1a) and the magnetic field of a power generator (1b) into a same magnetic field coupling of a same rotor (10), so that the rotors (10) of electric motor (la) and the power generator (1b) have the same rotational direction, and an exciting winding (12a) of the electric motor (1a) and a field winding (12b) of the power generator (1b) change and transmit phases sequentially to a phase voltage by a DC brushless drive controller (40), so that an interference effect on the counter electromotive force of the electric motor (1a) and the counter-electromotive force of the power generator (1b) is changed to a positive effect.

摘要： A highly efficient circulator system is provided, useful for hydronic systems, including both heating and cooling systems. The stand-alone circulator motor is controllable by input from certain sensors, preferably thermal sensors, which provide data enabling the controller of the brushless pump motor to vary its flow output to meet changes in systems loads. The circulator has a ceramic permanent magnet rotor, such as a ferrite, with an electronically, preferably sinusoidally, commutated, electro-magnetic stator controlling the input of electrical power.

摘要： A charging assembly includes a conduit assembly configured to be fluidly coupled with a pre-existing conduit through which a liquid flows, and a hydroelectric generator coupled with the conduit assembly such that at least part of the liquid flowing through the pre-existing conduit flows through the hydroelectric generator. The hydroelectric generator is configured to create an electric current based on flow of the liquid through the hydroelectric generator. The assembly also includes an energy storage assembly conductively coupled with the hydroelectric generator. The energy storage assembly is configured to store electric energy of the electric current created by the hydroelectric generator.
