Re: CIM Motors with gearboxes: torque

A cim has a Stall Torque of 2.42 N-m, or 343.4 oz-in, according to:
http://www.andymark.com/ProductDetai...ctCode=AM-0255

A toughbox has a gear reduction of 12.75:1 , which means that the speed is reduced by a factor of 12.75 and torque is increased by the same factor.

total torque of a toughbox with 1 cim: 30.855, and twice that with two cims.

please note that the above is the stall torque, and it is not recommended to work close to it.
