150 Foot-Pound Stepper motor
« on: February 10, 2007, 12:42:07 PM »
Does anyone know of a stepper motor that can generate around 150 foot-pounds of force?

150 foot-pounds is up in the modern automobile range.  That's a LOT of torque.  I'm curious to see the answer to this question, but what on earth do you need that much torque for?

im still not sure about the units and this isn't a stepper but try this motor:

also if you want a motor that strong you have to pay big $$$

i don't think you'll get that sort of torque from a gear stepper motor without a lot of gearing. (or a HUGE motor.)

Admin posted this guy's website the other day.
one of the usefull/interesting things i saw there was the guys homebrew high power servos:

can anyone say "high torque"?

dunk.

after all that gearing you probably get like 1rpm

also what is the black tank like thing connected to the rods in the tutorial link that dunk posted? and what is a Linear Actuator?

Maybe I did the math wrong... it shouldn't be over 1 hp at max. So what are some stepper motors that range from 0.3 hp up. I think that works out to 0.21 Newton*meters/sec or 21 Newton*cm/sec
