A wet-type high-voltage resistant rotating electromagnet with double magnetic steel magnetic circuit symmetry

Abstract

The invention discloses a wet-type high-voltage-resistant rotating electromagnet with a symmetrical double magnetic steel magnetic circuit, which includes a front section cover and a rear end cover. A rotor part is installed on the front section cover and the rear end cover. The rotor part has two Stator components are respectively installed on the front section cover and the rear end cover on the side; the rotor component includes a rotor shaft mounted on the front end cover and the rear end cover through the first bearing and the second bearing, which can rotate around the central axis. A rotor is interference-connected on the rotor shaft; the stator part includes a first permanent magnet, a second permanent magnet, a first yoke, a second yoke, a third yoke, and a fourth yoke installed on both sides of the rotor. , coil and coil holder. In this embodiment, through the improved double magnetic steel electromagnetic design, a wet high-voltage resistant rotating electromagnet with a symmetrical magnetic circuit can also be produced by mechanical processing. The structure is simple and the processing is convenient; and a simple and reliable high-voltage resistant structure is adopted. , so that the electromagnet has the ability to work in a wet state.

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 wet-type high-voltage-resistant rotating electromagnet with a symmetrical double-magnet 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 e...
