Pairs of Complementary Unidirectionally Magnetic Rotor/Stator Assemblies

Abstract

Pairs of unidirectionally magnetic rotor / stator assemblies are mounted for synchronous rotation and complementary, so that one creates pulsating positive current flow and the other creates pulsating negative current flow, as the rotor and stator in each assembly are rotated with respect to each other. The pulsating positive current flow and pulsating negative current flow are combined at a desired phase angle to create alternating current, without power loss due to reversal of current flow.

Description

TECHNICAL FIELD[0001]This invention relates to pairs of complementary unidirectionally magnetic rotor / stator assemblies, in which the rotors or stators have magnets with all their magnetic fields aligned parallel to the axis of rotation and their magnetic poles all pointing in the same direction, with the magnets inducing electric current in adjacent associated coils as the rotors or stators in each assembly rotate with respect to each other.BACKGROUND ART[0002]Magnets have both north and south poles, and a magnetic field extending between and around the poles. When a mechanical force causes a wire or other electrical conductor to move through a magnetic field, an electric current is induced to flow in the electrical conductor. This is the principle of an electric generator. Conversely, when an electric current flows through a wire or other electrical conductor, a magnetic field is created around the conductor, and if the conductor is in an existing magnetic field, the magnetic fiel...

Benefits of technology

This configuration reduces energy loss and 'cogging' by maintaining consistent current flow direction, enabling efficient energy conversion and stable power generation with reduced startup requirements, suitable for applications with varying rotational speeds.

Problems solved by technology

However, this alternating current creates drag or “cogging” due to the interactions of the reversing current flow with the magnets in the generator.

Also, substantial energy is lost because current flow causes magnetization of the cores of the coils, and reversal of that current flow causes demagnetization and then opposite magnetization of those cores, which wastes energy.

This “cogging” in a wind generator means that higher wind speeds may be required to start the generator rotating, thus raising the “start up speed.” Further, a wind generator may not be able to provide useful power until a minimum “cut in speed” of the wind generator has been reached.

If the generator of this invention is used in a wind generator or other application in which the rotational speed of the rotor / stator assemblies will vary, then the frequency and voltage of the alternating current from the coils of the rotor / stator assemblies will vary with the wind speed, which may not provide useful power.

However, the rectifier may not be able to provide useful DC current unless it is provided with a minimum amount of alternating current.
