Direct acting two-way inserting sheet type electromagnet

Abstract

The invention provides a direct acting two-way inserting sheet type electromagnet which comprises a stator part, an armature part, a housing and a front / back end cover, wherein the stator part is arranged outside the armature part, and the stator part comprises a first stator retainer, a second stator retainer, a third stator retainer, a fourth stator retainer, a stator silicon steel sheet, a first coil retainer, a second coil retainer, a first control coil, a second control coil, a permanent magnet and a housing; the shapes of the four stator retainers are as the same as one another, the four stator retainers are hollow semi-cylinder bodies, and inserting grooves evenly distributed along the radial direction are arranged on the outer peripheral surface of a cup body; and the armature part comprises an armature retainer, an armature inserting sheet and a push rod, the armature retainer is formed by high-intensity enhanced nylon material in an injection molding way, and rectangular inserting grooves which have a certain depth respectively and evenly distributed are arranged on the outer peripheral surface of the armature retainer.

Description

technical field [0001] The invention belongs to an electro-mechanical converter used for an electro-hydraulic control element in the field of fluid transmission and control, and in particular relates to a direct-acting two-way plug-in electromagnet. Background technique [0002] In the electro-hydraulic proportional / servo control system, the electro-mechanical converter as a key component of the electro-hydraulic proportional / servo valve has a small working stroke, and its performance mainly pursues the real-time and precision of the conversion of electric energy and mechanical energy, that is, it is required to ensure While maintaining a certain output force / torque, try to achieve a higher dynamic response. In addition, in special environments (such as vehicle or aerospace applications), it is also required that the valve and the electro-mechanical conversion mechanism can reduce the overall size and weight as much as possible while ensuring the output power.

Problems solved by technology

However, the eddy current effect of this structure is serious under the control of the AC mode, which increases the useless power loss of the electro-mechanical converter, and the coil heats up seriously. dynamic performance

In addition, the characteristics of the integral structure of the stator and rotor also determine that a whole piece of metal must be used as the soft magnetic material of the iron core, so that the weight remains high and affects the power-to-weight ratio of the whole machine
