ABSTRACT:
A motor utilizing permanent magnets or electromagnets wherein the magnets are arranged with like poles facing one another in a normally repelling position. A magnetic flux field suppressor having a non-magnetic portion and a magnetically permeable portion is disposed between the magnets for repeatedly causing a magnetic repelling and attracting action as each portion of the suppressor is repeatedly moved into alignment between like poles of the magnets. The magnetically permeable portion is comprised of a plurality of magnetically permeable sheets interleaved with thin layers of a non-magnetic material. During the attracting action the magnetic flux lines of each magnet are conducted within a confined pathway by the sheets as they are directed therethrough between the magnet poles. The motor may be constructed for both reciprocating and rotary operation.
