A single-phase rotary type proportion electromagnet comprises stators, a front end cover and a rear end cover are installed on the front sides and the rear sides of the stators, a rotor is installed in the stators, an output shaft is installed on the rotor and connected with a reset torsion spring, and the stators are composed of a first stator, a second stator, a third stator and a fourth stator which are coaxially arranged. N rotor teeth are uniformly distributed in the circumferential direction of the rotor, the rotor teeth form rotor magnetic surfaces, and each rotor magnetic surface and the stator magnetic surface form a working air gap; symmetrical grooves are formed between the second stator and the third stator along the interface, the grooves are reversely buckled and spliced to form an annular groove, a magnetism isolating ring is placed in the annular groove, and a control coil is wound on the magnetism isolating ring to form control magnetic flux. A first permanent magnet and a second permanent magnet are arranged between the first stator and the second stator and between the third stator and the fourth stator respectively to form polarized magnetic flux. According to the invention, an approximately horizontal moment angle characteristic curve can be obtained, and a proportional position control characteristic can be obtained after a reset torsion spring is additionally arranged.
Description
technical field [0001] The invention relates to an electro-mechanical converter for an electro-hydraulic digital valve in the field of fluid transmission and control, in particular to a single-phase rotary proportional electromagnet. Background technique [0002] Rotary valve is a reversing valve that uses rotary motion to change the relative position of the valve core and valve sleeve, so as to change the flow path inside the rotary valve, and finally realize the opening and closing or reversing of the flow path. Rotary valves can be driven manually, mechanically, or directly by electric motors, motors, and rotary solenoids for precise servo / proportional control. Compared with slide valves or cone valves, rotary valves have the advantages of high reliability, simple structure, high operating frequency, and strong oil pollution resistance, and can be widely used in hydraulic systems with high-speed switching, high-speed excitation, and high-speed reversing , especially when...
