A wet type high voltage resistant rotating electromagnet with symmetrical magnetic circuit

Abstract

The invention discloses a wet high voltage-resistant rotating electromagnet with a symmetrical magnetic circuit, comprising a front end cover and a rear end cover. A rotor component is installed on the front end cover and the rear end cover. Stator components are respectively installed on the front end cover and the rear end cover at the two sides of the rotor component. A first yoke and a second yoke are in sealing connection through a first sealing ring. A third yoke and a fourth yoke are in sealing connection through a second sealing ring. The first yoke and the front end cover are in sealing connection through a third sealing ring. The fourth yoke and the rear end cover are in sealing connection through a fourth sealing ring. A coil holder and the second yoke are in sealing connection through a fifth sealing ring. The coil holder and the third yoke are in sealing connection through a sixth sealing ring. The wet high voltage-resistant rotating electromagnet has the characteristics of simple structure and easy processing, and can work under wet condition.

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 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 dama...
