Biconical disc ratio electromagnet

Abstract

The invention discloses a biconical disc ratio electromagnet. An armature (1) is formed by enclosing a bottom (11) and an annular side wall, wherein, a V-shaped groove (12) is arranged on the annular side wall, and the annular side wall is positioned in an annular space formed by a magnetic conduction iron core column (7) and a magnetic conduction outer shell (4); a clearance between the annular side wall and the magnetic conduction outer shell (4) forms a radial operating air gap I (101), and a clearance between the annular side wall and the magnetic conduction iron core column (7) forms a radial operating air gap II (102); a push rod (3) penetrates through the bottom of the magnetic conduction iron core column (7) and the bottom (11) of the armature (1), is fixedly connected with the armature (1), and is in the relationship of relative slip with the magnetic conduction iron core column (7); and a clearance between the bottom (11) and the magnetic conduction iron core column (7) forms an axial operating air gap (103). The biconical disc ratio electromagnet has ratio specialty and high ratio of output force to power.

Description

technical field [0001] The invention relates to a proportional electromagnet with a disc structure. Background technique [0002] Proportional electromagnets have horizontal displacement-force characteristics and are widely used in proportional control systems. However, the current structural form is mainly of the solenoid type, which is suitable for driving small and medium-sized loads. In some occasions that require high load output force Difficult to apply. The disc-type DC electromagnet has a large electromagnetic attraction in a very short stroke, but the traditional disc-type electromagnet attraction decreases rapidly with the increase of the working air gap, and it is difficult to meet the output requirements of the proportional characteristic, so its It is mainly suitable for loads working in the suction state and fast-moving occasions, so it is generally used in lifting electromagnets and electromagnetic chucks.
