Sheave reversing type magnetic actuator

The invention relates to a sheave reversing type magnetic actuator. The sheave reversing type magnetic actuator comprises three main parts of a sheave mechanism, a magnet timing cycle reversing mechanism and a driving plate. If two states of magnets are put together (heteropoles are opposite or homopoles are opposite), when the two magnets attract (or repel) to move to one specific position, the polarity of one magnet changes, at the moment, the two magnets repel (or attract) to move to another specific position, the polarity of one magnet changes, the two magnets move continuously in this way, and then a mechanical system capable of continuously moving can be formed. By means of the intermittent movement characteristic of the sheave mechanism, the driving plate drives a sheave to intermittently rotate one magnet, thus, the two magnets can continuously reciprocate under the effect of magnetic force, and meanwhile the driving plate is driven to continuously output rotational movement to output power externally
