Abstract

The invention discloses a rotary electromagnet with symmetric magnetic paths. The rotary electromagnet comprises a front fragment cover and a rear end cover, wherein a rotor part is arranged on the front fragment cover and the rear end cover, stator parts are respectively arranged on the front fragment cover and the rear end cover at the two sides of the rotor part, the rotor part comprises a rotor shaft, the rotor shaft is arranged on the front fragment cover and the rear end cover via a first bearing and a second bearing and can rotate around a central axial line, a first permanent magnet, a second permanent magnet, a first rotor fragment, a second rotor fragment and a third rotor fragment are arranged at each of the two sides of the rotor shaft, and each stator part comprises a first yoke, a second yoke, a third yoke, a fourth yoke, a coil and a coil retaining rack. With the improved dual-magnetic steel electromagnetic design, the rotary electromagnet with the symmetric magnetic paths also can be fabricated by a mechanical processing mode, is simple in structure and is convenient to process.

Description

technical field [0001] The invention belongs to an electric-mechanical energy conversion device in the field of fluid transmission and control, in particular to a rotating electromagnet with a symmetrical magnetic circuit. Background technique [0002] In recent years, the 2D digital servo valve using the principle of servo screw mechanism has been widely used in metal material testing machines, earthquake simulation shaking tables and related aerospace fields because of its simple structure, fast response speed, high precision, and strong anti-pollution ability. have been widely used. Conventional electro-mechanical converters for 2D digital servo valves are generally rotary electromagnets with mixed excitation. Compared with the former, it has the following advantages: First, it adopts axial phase separation, and the control winding can use toroidal coils. The winding and off-line process is simple, and the coil paint is not easy to be damaged. structure; second, the axi...
