Permanent magnetic power system comprising a first magnet (1) and a second magnet (2) which are fixedly arranged, a third magnet (3) arranged in a sliding manner between the first magnet (1) and the second magnet (2), a first magnetic shield member (4), a second magnetic shield member (5) and a magnetic shield member drive device; the third magnet (3) and the first magnet (1), and the third magnet (3) and the second magnet (2) are both arranged to be mutually repulsive; the first magnetic shield member (4) is provided between the third magnet (3) and the first magnet (1), and the second magnetic shield member (5) is provided between the third magnet (3) and the second magnet (2); and the magnetic shield member drive device is used for driving the first magnetic shield member (4) and the second magnetic shield member (5) to move in/out between the third magnet (3) and the first and second magnets (1, 2). By utilizing the principle of attraction and repulsion between magnets, the permanent magnetic power system forms a push force and an attraction force on the third magnet (3) which superpose with each other to work in the whole course, enabling the reciprocating motion thereof. The permanent magnetic power system has a simple structure, a rational design, low energy consumption, high magnetic energy utilization, facilitates speed adjustment, the magnets can be repeatedly magnetized for utilization, costs are low, and it is suitable for widespread application. |
