| 简介 |
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. The center section of the spool reciprocates over a fixed magnetic actuator having a permanent magnet at each end of an elongated tubular shaft. The two permanent magnets have extension members disposed in the shaft with inward ends that are in spaced apart relation to form a gap therebetween. 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. |
