I'm curious about the following & I want to know everyone's opinion.

I want something to pull back a spring (650N/m) and Im curious if a solenoid can do the job.
The spring has to be able to be compressed about 5 cm where it will get latched. The whole thing is portable and battery operated preferably if possible.

1.) How big of a solenoid is required to do the job? How much voltage & How long does it have to be, how many coils ect?? Rough estimates are fine

2.) Is it possible/plausible to build such a required solenoid? tips


Thanks, I appreciate your input!!:D

"want everyone's opinion"
I don't know. You may want to use a motor and gears.
Perhaps wind a clock spring.

What are you doing?

Best guess I come up with, force of 117 oz; long throw solenoid , 24V DC@7A pulls 59 oz 4.6 cm. 10 % duty. Solenoid might be doable 20A with 18 "C" NiCd cells in series. I'd use a motor with gear reduction, 3V 100mA+-.
