DC 24V push-pull electromagnet DO2551
25mm diameter, 51mm length, 5-15mm stroke, 6-24 volts
The circular shape design enables it to generate a large magnetic force in a small volume, with good magnetic circuit performance, long stroke, large force and fast response speed.
The push-pull electromagnet is mainly composed of shell, wire rack, copper wire, copper tube, iron core, movable sliding rod, ejector rod, stopper, front and rear cover, wire, etc.
The working system is divided into: long-term working system, short-term working system and repeated short-term working system.
Long-term working system: The working time of the electrical appliance is very long, generally not less than the heating time constant. During the working period, the temperature of the product reaches or is close to the temperature rise limit (the temperature of the product will no longer rise). After the work is stopped, the temperature of the product drops to the temperature of the surrounding medium. Long-term working system heat dissipation is the main.
Long-term working current density can be 2～4A/mm
Short-term working system: The working time of the electrical appliance is very short, and one side is less than the heating time constant. During the working period, the temperature of the product does not reach the temperature rise limit. After the work stops, the temperature of the product drops to the temperature of the surrounding medium. The short-term working system (the heat capacity of the product itself) is the main aspect.
