Abstract
Methods and apparatus that employ a coil-less magnetoelectric flux switch arrangement to repeatedly switch magnetic flux from at least one permanent magnet for the purposes of generating motive force and/or electrical energy.
Claims9
An apparatus for switching magnetic flux comprising:
- a permanent magnet having a north pole and a south pole;
- at least two magnetic flux conductors operably connected to define different magnetic paths between the north pole and the south of the permanent magnet;
- for each magnetic path, at least one coil-less magnetoelectric flux switch operably positioned along the magnetic path;
- and
- a control system operably connected to the magnetoelectric flux switches to selectively switch a flow of magnetic flux from the permanent magnet through the different magnetic paths.

A method for switching magnetic flux generated by a permanent magnet having a north pole and a south pole, the method comprising:
- operably connecting at least two magnetic flux conductors to define different magnetic paths between the north pole and the south of the permanent magnet;
- for each magnetic path, operably positioning at least one coil-less magnetoelectric flux switch along the magnetic path;
- and
- controlling the coil-less magnetoelectric flux switch to selectively switch a flow of magnetic flux from the permanent magnet through the different magnetic paths.

A method for generating a flow of current in a pickup coil associated with switching of magnetic flux generated by a permanent magnet having a north pole and a south pole, the method comprising:
- operably connecting at least two magnetic flux conductors to define different magnetic paths between the north pole and the south of the permanent magnet;
- for each magnetic path, operably positioning at least one coil-less magnetoelectric flux switch along the magnetic path;
- providing at least one pickup coil wound around at least one of the magnetic flux conductors;
- and
- controlling the coil-less magnetoelectric flux switch to selectively switch a flow of magnetic flux from the permanent magnet through the different magnetic paths such that a flow of current is generated in the pickup coil by alternately switching the flow of magnetic flux through the at least one of the magnetic flux conductors.
