Ned Simmons fired this volley in
:

. A 20 ft-lb torque motor would be
enormous. When I was a kid I had a pair of torque motors I scavenged
from a Univac 2 tape drive. They were about the size of a cast iron
1/3 HP induction motor and could be stalled by grabbing the shaft.


But Ned, keep in mind that those motors were designed to produce that
torque all the way up to several hundred RPMs.

Mine only needs 3+ RPM... so I multiply the motor torque with belting or
sprocket drives.
