Method and apparatus for radial electromagnetic power arrays

A system comprising

• a first linear actuator motor comprising
• a magnetically permeable outer flux containment shell, and
• a magnet core assembly disposed within the outer flux containment shell, the magnet core assembly comprising
• a magnet stack comprising one or more magnets,
• each magnet having a Bloch wall,
• such that the magnet stack is configured to reciprocate within the outer flux containment shell with a stroke where each permanent magnets has
• a first beginning of stroke position, and
• a second end of stroke position, and
• a plurality of coils, each coil comprising at least one wire loop around at least a portion of the magnet stack, each coil having an electro-magnetic center, such that the Bloch wall of each magnet is offset from the electro-magnetic center of each coil at both the first beginning of stroke position and the second end of stroke position,
• such that the outer flux containment shell provides magnetic flux containment and routing, and the magnet stack is self-levitating;
• and
• a first linear actuator generator comprising
• a magnetically permeable outer flux containment shell;
• and
• an magnet core assembly disposed within the outer flux containment shell, the magnet core assembly comprising
• a magnet stack comprising one or more permanent magnets, and
• a first coil comprising at least one wire loop around at least a portion of the magnet stack, such that the outer flux containment shell provides magnetic flux containment and routing, and the magnet stack is self-levitating.

An electromagnetic motor energy recovery method comprising

• providing a first linear actuator motor comprising
• a magnetically permeable outer shell,
• a magnet core assembly disposed within the outer shell, the magnet core assembly comprising
• a magnet stack comprising one or more magnets,
• each magnet having a Bloch wall,
• such that the magnet stack is configured to reciprocate within the outer flux containment shell with a stroke where each permanent magnets has
• a first beginning of stroke position, and
• a second end of stroke position, and
• a plurality of coils in proximity to the magnet stack, each coil having an electro-magnetic center, such that the Bloch wall of each magnet is offset from the electro-magnetic center of each coil at both the first beginning of stroke position and the second end of stroke position,
• such that the outer shell provides magnetic flux containment and routing, and the magnet stack is self-levitating, and
• a controller;
• levitating the magnet stack within the outer shell of the first linear actuator;
• applying, with the controller, a plurality of supply voltage pulses to one or more of the plurality of coils over a first time interval, thereby causing the magnet stack to move in a first direction;
• recovering energy from the one or more of the plurality of coils by establishing, at a second time interval, an electrical connection between the one or more of the plurality of coils and a pulse recovery element.
