electromagnet for tool dock

[dc42]

@spirit-robotics what position is the fan voltage section jumper in?

And what VIN voltage are you using?

@dc42 this is a test from my power supply, just to check.

I want to connect the electromagnet to a pwm fan pins at 5V, from the reading I understand that it will work because the board have the flyback diode and the current is small.

My idea is hold with the electromagnet my tool, I already tested the electromagnet with the DC power supply and the current is only 0.09 ampers, but still have enough force to hold the tool without getting hot the electromagnet.

Please let me know your recommendations.

Hi again
My solution is still working good. It's quiet simple.
I could share my solution...

Cheers

@gruna-studio Thanks, sure if you like, I already have my design, I want to hold a small iron plate attached to the tool with the electromagnet, no moving parts.

Im only double check how operate the electromagnet without burn again my board.

@spirit-robotics Hi everyone, weekend was busys, but today I find the time to test. It's work now the electromagnet into the PWM fans. Thanks to all
