Electromagnetic clutch

[mawad]

Dear All,
I am looking for a small lightweight electromagnetic clutch which is engaged and transmit power by default and when I activate it, it will disengage and overrun a timing pulley. The maximum transmitted torque is about 0.6Nm and maximum speed is about 3000rpm. Do you have an idea which company can I check to find this clutch?
Regards,
mawad

You didn't state where you are based, but Magnetic Technologies (

) might be an option. They are US-bsaed, but have reps all over the world.

Upon perusing their standard product list, it looks like they may have something close to your requirements.
