Abstract: This is a novel magnetic configuration that is to be used to build extra efficient PM motors. This magnetic configuration uses mono polarities of permanent magnet as field-poles instead of dipolar field-poles configuration. Armature teeth are built, energized and used very differently in this magnetic configuration. This configuration revitalizes repulsive force three times inside a running PM motor without using more than usual current. Revitalized repulsive force allows using very strong permanent magnets, which produces heavy attractive force in the same running motor. The revitalized repulsive force along with the heavy attractive force produces extra output power in the motor at no-cost. This magnetic configuration is self-sufficient and unparalleled. It could only be implanted in new designs of PM motors. This magnetic configuration has been built around new experimental findings. The functions of three newly invented electrical machines including a fully-functional prototype validate this magnetic configuration.

Abstract: A system for transferring electric power is provided. A power supply conductor conducts a power supply current that generates a first resultant magnetic field. An electric motor has a power input terminal connected to the power supply conductor and a movable output component. A generator has a movable input component connected to the movable output component such that the movable output component causes movement of the movable input component. The generator converts the movement of the movable input component into a power output current to the power output terminal that generates a second resultant magnetic field. A plurality of field line guides are positioned for field lines of the second resultant magnetic field to couple to the plurality of field line guides and are formed to guide the field lines into a helical shape.

Abstract: The invention relates to a starter for a motor vehicle heat engine. The starter includes a rotary electric machine provided with a stator (3). The stator (3) includes a magnetic pole assembly wherein a permanent magnet (5) forms at least two poles of the magnetic pole assembly. The permanent magnet may have a cylindrical shape and be molded from a combination of magnetic particles embedded within a non-magnetic binder. Using this structure, the number of magnets used to create the stator may be limited in number, thereby limiting the necessary assembly steps to create the stator.
