Where should we pay attention to the selection of DC electromagnet

DC electromagnets have very different kinds, so many products are classified. What should we choose for our users? Let's look at the selection method of DC electromagnet.
First of all, one problem we should pay attention to is the output requirements of the electromagnet.

1, itinerary / strength

What is the stroke: the displacement of the slider relative to the full suction position.
Electromagnetic iron will generate power when it is electrified, and the strength of the position in different sizes is different. The rule is that the larger the stroke, the smaller the force.
The ideal state is: the force / stroke curve generated by the electromagnet, which just meets the strength / stroke curve of the application demand.

2. The response time of the electromagnet

Definition: starting from the voltage applied to the electromagnet, and the time required to complete the displacement when the slide bar is completed.

3, load cycle Duty Cycle={power on time On time/ (power on time On time + power failure Off time)}X100%

4. The longest electrifying time of electromagnet

When the electromagnet is heated during energizing, the load cycle or the longest electric time and the power of the electromagnet determine the temperature rise of the electromagnet when working.
The temperature rise of the electromagnet and the ambient temperature at work determine the choice of the insulation grade of the electromagnet material.
(insulation grade corresponding to temperature C: A=105, E=120, B=130, F=155, H=180, N=200, C=220+)
