    摘要: The present invention refers to a linear electric generator, comprising: at least one intake port; at least one expansion chamber, and at least one expansion piston; at least one central cylinder; at least two reduced cylinders, wherein the diameter of said reduced cylinders is smaller than the diameter of the central cylinder, and wherein each reduced cylinder comprises a partition; at least one electric power-generating set of pistons, wherein each piston of said set of pistons is located inside the central cylinder and is suitable to linearly move inside the inner void of a reduced cylinders through the partitions of the reduced cylinders, and wherein each said piston is connected to an oscillator; at least one fluid chamber suitable to comprise incompressible fluid, wherein said fluid chamber is the void between the edge of the expansion piston closer to the electric power-generating pistons and the electric power-generating pistons themselves; at least two sets of magnets, wherein each set of magnets is attached to an oscillator; at least two end sections that comprise coil windings; and at least one outlet port, suitable to allow the evacuation of fluids from said expansion chamber. The invention also refers to a method for energy transformation.

    摘要: Circuitry for directly providing drive power to a BLDC motor having separated coils, comprising unipolar controlled current sources for supplying current to each of the separated coils; a controller, for controlling the level and phase of the unipolar controlled current sources; a polarity switch for converting the unipolar current to a bipolar (AC) current, supplied to the separated coils. The controller is adapted to shape the current being fed to the BLDC motor by the current source via the polarity switch, to be in phase with the back EMF sensed on the separated coils, and of a magnitude that corresponds to a required torque.
