One kind of electromagnet is proportional electromagnet, so what are the proportional electromagnets? Generally speaking, the basic type of proportional electromagnet is divided into stroke control type; Force control type; Position adjustment type.

A stroke controlled proportional electromagnet: its input and output characteristics are current to force and then to displacement, which is proportional to the input current and the output displacement transformed by the load spring. It is generally used in places with large output stroke and is mostly used for direct control valves.

Two force control proportional electromagnet: its input and output characteristics: the current directly outputs the force. The output force is proportional to the input current. It has nothing to do with the armature displacement in the working area, that is, it has the characteristics of horizontal suction. It is generally used in places with short travel. It is commonly used as the leading level.

The input and output characteristic of the three position adjustable proportional electromagnet is that the current is directly to the armature position, and the armature displacement is directly proportional to the input current, but it has nothing to do with the reaction force. The specific force is determined according to the load demand within the larger suction force. The main application occasion is the closed-loop with armature position feedback, which is often used in direct control valves with high control accuracy.

Anyang Kaidi proportional electromagnet product is an electromechanical conversion device, which is used together with the proportional control amplifier in the DC 24V electro-hydraulic proportional control system and acts on Rexroth proportional flow valve and proportional direction valve. Within the range of rated stroke and rated current, its output force and displacement are proportional to the input current. Stepless regulation of the input current within the rated range can realize stepless speed regulation, commutation and remote control of the actuator of the hydraulic system within the rated range.
