摘要:
A rotational difference is generated between a first and a second rotor and a third rotor, which causes an induced current to flow in a first rotor winding. This causes a torque to act between the first rotor and the third rotor. The rotary magnetic field generated by the induced current flowing through a second rotor winding interacts with a second stator, which in turn generates an induced electromotive force in a second stator winding. The induced electromotive force is applied via a phase adjustment circuit to a first stator winding, which generates a rotary magnetic field and causes a torque to act between the first stator and the third rotor. The rotary magnetic field generated by the second rotor winding and the induced current flowing in the second stator winding causes a torque to act between the second stator and the second rotor.

A microelectromechanical system (MEMS) device is used to transfer power from a source generator to a power generator that delivers electrical power to a load, while maintaining electrical isolation between the source generator and power generator for size critical applications where transformers or coupling capacitors would not be practical, but where electrical isolation is desired.

摘要:
An electric motor-generator has a rotor (1), a stator including soft ferromagnetic cores (3, 5) and coils (4, 6), permanent magnets (2) having pole axes in a plane radial to an axis of rotation of the rotor, means for mounting the magnets, the cores and coils to the rotor and stator, and means for energizing the coils. The rotor is caused to rotate by attraction of the magnets to the cores (5) as the magnets and cores approach one another, an opposite attraction force between the magnets and the cores being neutralizeable by energizing the coils (6) as the magnets and cores move apart. The cores are C-shaped and a magnetic circuit is formed when the magnets and cores are in proximate alignment.

An electric starter motor and generator is integrated into the structure of an internal combustion engine by making the ferromagnetic pistons of the engine the relatively moving elements in the starter and generator. A coil is solenoidally wound around each sleeve of the engine. An electronically controlled switch sends battery current into an appropriate coil inducing a powerful magnetic field therearound. The magnetic field and piston interact resulting in a powerful magnetic force which moves the piston and thus cranks the engine. At appropriate times in the operation of the engine, fuel to the same can be shut off and the engine run as a high speed electric motor.
