Dragging dual well oil smoke extractor for rare earth permanent magnetic no gear synchronization

The utility model relates to a rare earth permanent magnetism no-gear synchronized traction twin well oil extracting machine, which consists of a rare earth permanent magnetism synchronized traction motor, a traction wheel, an electromagnetism arrester, a photoelectricity rotating coder, an internal contracting brake device, a guide wheel, a frequency conversion controller, a control cabinet, a traction wirerope, and a rack. By the traction wheel and the friction (traction force) produced by the deadweights of the two well oil extracting rods hung on the two ends of the traction wirerope, via the traction of the guide wheel, the two well oil extracting rods move repeatedly up and down, the two oil extracting rods of the two oil wells act as counter weights mutually. Since the no-gear direct drive is adopted, without the mechanical wastage of gearing mesh of the reduction box, lube changing is not needed; the machine gets rid of the walking beam, the horsehead, the special weight counterbalance, the crank conn
