Patent ID: 8786143

Claim:
A magnetically actuated reciprocating motor, comprising: a frame; a solenoid fixedly supported by said frame, said solenoid having a first end and an opposite directed second end, said solenoid configured to have a first polarity at said first end and a second polarity at said second end in a first energized state and said second polarity at said first end and said first polarity at said second end in a second energized state, said solenoid comprising a spool having a coil of a wire wrapped around a center section, said center section having a generally open center; a magnetic actuator reciprocally received in said open center of said coil, said magnetic actuator having an elongated tubular shaft with one or more walls defining a tubular chamber between a first end and a second end of said shaft, a first permanent magnet disposed inside said tubular chamber at said first end of said shaft and a second permanent magnet disposed inside said tubular chamber at said second end of said shaft, said first permanent magnet having an end disposed toward said first end of said solenoid that is magnetically charged with an actuator polarity that is one of said first polarity and said second polarity, said second permanent magnet having an end disposed toward said second end of said solenoid that is magnetically charged with said actuator polarity; means operatively interconnecting said magnetic actuator and a work object for converting reciprocating movement of said magnetic actuator to rotating movement so as to rotate said work object; a source of power configured to electromagnetically energize said solenoid; switching means electrically interconnecting said source of power and said solenoid for alternatively switching said solenoid between said first energized state and said second energized state; and controlling means operatively engaged with said switching means for controlling the operation and timing of said switching means so as to switch said solenoid between said first energized state and said second energized state to reciprocatively drive said magnetic actuator relative to said solenoid and rotate said work object.
