Eric:
You are correct, I completely forgot about the armature V-I when I did the horsepower calculation.
Unfortunately, the torque value (33 oz-in) came from the data sheet (chart - average motor characteristics, curve T/N(FB) ).
As to armature current: the table on the Electrical Data page says the armature current is 1.5 amps. So, 220V x 1.5A = 330Watts. Which is almost 1/2 horsepower (!!) at 746W/hp. I don't know how the field and armature powers inter-relate.
It sure seems like an awful lot of power in to produce only 33 oz-in torque out.
robotic regards,
Tom
