Abstract
The utility model provides a reverse-magnetic type bistable electromagnetic reciprocating drive mechanism, comprising a pole shoe, a pole shoe installing seat, an excitation loop, a bracket, a movable magnetic circuit, and a permanent magnet. The utility model is characterized in that the pole shoe installing seat is fixed on the upper and the lower ends of the bracket, the internal side is oppositely fixed with pole shoes; the pole shoe is wrapped with the excitation loop; the movable magnetic circuit is arranged between the upper and the lower pole shoes, the upper and the lower sides of the two ends are provided with the permanent magnets, and the polarity of the permanent magnet on the same lateral surface is opposite. The pole shoe fixed on the pole shoe installing seat is a fixed point, the permanent magnet on the upper and the lower sides of the movable magnetic circuit is a movable point, when in stable (or static) state, the movable magnetic circuit adsorbs on one side of the pole shoe through the permanent magnet, a comparative short magnetic circuit is formed by the pole shoe, the pole shoe installing seat, the permanent magnet and the movable magnetic circuit, since the utilizing rate of energy sources is high, when the excitation loop is electrified, the movable magnetic circuit will be excluded, and the other side will be adsorbed by the pole shoe, thus finishing the conversion of one stable state to another stable state.
Description
Affiliated technical field
The utility model provides a kind of reverse magnetic bistable electromagnetic reciprocating drive mechanism, belongs to the Drive technology field of containing electromagnet.
Background technology
The permanent magnetism reciprocating drive mechanism has multiple version at present, but substantially all has following problem: the driving mechanism power consumption of paramagnetic formula is big, and initial velocity is low, requires the machining accuracy height, the manufacturing cost height; The unreasonable structure of reverse magnetic, magnetic circuit is long or do not have closed magnetic circuit, and energy utilization rate is low.So driving mechanism price that can be practical is all very high, be difficult to substitute existing non-permanent-magnetism electromagnetic driving mechanism.
The utility model content
The purpose of this utility model provides a kind of reverse magnetic bistable electromagnetic reciprocating drive mechanism that can overcome above-mentioned defective, energy utilization rate height, excellent working performance.Its technical scheme is:
Comprise pole shoe, pole shoe mount pad, magnet exciting coil, support, movable magnetic circuit and permanent magnet, it is characterized in that: the pole shoe mount pad is fixed on the upper and lower end of support, its inboard is fixed with pole shoe in opposite directions, twining magnet exciting coil on the pole shoe, movable magnetic circuit is arranged between the upper and lower pole shoe, the upper and lower both sides at its two ends are provided with the permanent magnet corresponding with upper and lower pole shoe, and the permanent magnet polarity on the same side is opposite.Perhaps the pole shoe mount pad is fixed on the left and right end of support, its inboard is fixed with pole shoe in opposite directions, twining magnet exciting coil on the pole shoe, movable magnetic circuit is arranged between the left and right pole shoe, the and arranged on left and right sides at its two ends is provided with the permanent magnet corresponding with left and right pole shoe, and the permanent magnet polarity on the same side is opposite.
Described reverse magnetic bistable electromagnetic reciprocating drive mechanism, per 2 pole shoes are one group and are fixed on the pole shoe mount pad, be provided with the permanent magnet that is equal to the upper and lower both sides of its corresponding movable magnetic circuit.
