Description

technical field [0001] The invention relates to an electro-mechanical conversion mechanism for a proportional valve and a servo valve in a fluid control system, in particular to a low-power consumption high-voltage resistant bidirectional linear force motor. Background technique [0002] As an electromechanical conversion mechanism, the traditional proportional electromagnet is widely used in electro-hydraulic proportional valves, but its control current is often large and consumes a lot of power, which is difficult to meet the requirements of energy saving and easily leads to an increase in coil temperature. As the electro-mechanical conversion mechanism of electro-hydraulic proportional valves and servo valves, the linear force motor uses permanent magnets to generate polarized magnetic fields. Compared with traditional proportional electromagnets, it effectively reduces the power consumption of the electro-mechanical conversion mechanism. The typical linear force motor str...
