  • Patent number: 7629713
    Abstract: An electromagnetic motor includes a permanent magnet connected to a piston component of the motor and defining a linear reciprocating displacement path; and two electromagnets connected to the cylinder housing that periodically and alternately interact with the permanent magnet. The electromagnets are electrically connected to a power source for their selective activation. The electromagnets magnetically attract the permanent magnet over a respective first portion of the displacement path when un-activated and magnetically repulse the permanent magnet over a respective second portion of the displacement path when momentarily activated by the power source.
