K-type disc proportional electromagnet

Abstract

The invention discloses a k-type disc proportional electromagnet, comprising an armature (2), a push rod (6) and the like, wherein the longitudinal section of the armature (2) is in a k shape, the armature (2) comprises a bottom (21), an annular side wall (20) and an outer ring (25); the end part of the annular side wall (20) is provided with a V-shaped slot (22); the gap between the annular side wall (20) and a magnetic inductive outer shell (9) forms a radial working air gap I (203); the gap between the annular side wall (20) and a magnetic inductive core column (8) forms a radial working air gap II (204); the gap between the outer ring (25) and the magnetic inductive outer shell (9) forms an axial working air gap III (201); the gap between the bottom (21) and the magnetic inductive core column (8) forms an axial working air gap IV (202); and a permanent magnet (4) is arranged between the magnetic inductive core column (8) and the magnetic inductive outer shell (9). The k-type disc proportional electromagnet has the good proportional property and other characteristics.

Description

technical field [0001] The invention relates to a proportional electromagnet with a disc structure. Background technique [0002] As a proportional control electro-mechanical conversion device, the proportional electromagnet's function is to convert the current signal into a corresponding force / displacement signal. However, the output force and stroke of the usual solenoid proportional solenoid are limited by the structure, so it is difficult to apply to some occasions that require high load output force or long working stroke. Invention patent CN200910097989 discloses a biconical disc-type proportional electromagnet, which adopts the structure of a bi-conical disc-type armature, effectively combines the advantages of the traditional solenoid-type proportional electromagnet and disc-type electromagnet, and improves the output force; However, there still exist the defects of poor proportional characteristics and limited improvement of output force.
