Abstract: A magnetically actuated reciprocating motor utilizes the stored energy of rare earth magnets and an electromagnetic field provided by a solenoid to reciprocally drive a solenoid assembly. A converting mechanism, such as a connecting rod and crankshaft, converts the reciprocating motion of the solenoid assembly to power a work object. The solenoid assembly comprises a solenoid having a nonferromagnetic spool with a tubular center section and a coil of wire wrapped around the center section. A magnetic actuator has a permanent magnet at each end of an elongated shaft that is received through the center section of the spool. A switching mechanism switches magnetic polarity at the ends of the solenoid so the solenoid assembly is alternatively repelled and attracted by the permanent magnets. A controlling mechanism interconnecting an output shaft and the switching mechanism provides the timing to switch the polarity of the solenoid and reciprocate the solenoid assembly.

Abstract: To provide an actuator that can flexibly and softly move like muscles, can maintain a stable operation over a long period of time, can generate a strong driving force, has a rapid input response, has a favorable sensitivity, has a high energy conversion efficiency, and can be accurately controlled, a coil is embedded in a magnetic elastomer obtained by mixing a powder-like ferromagnetic or highly magnetic permeable material with an elastomer, so that the coil can be electrically connected. By electrically connecting the coil, a magnetic field generates in the coil and around the coil. The magnetic field penetrates the magnetic elastomer. When the magnetic field generates in the magnetic elastomer, deformation force acts on the magnetic elastomer by the magnetic force acting on each portion in the magnetic elastomer. Thus, driving force can be obtained.
