Re: vexta steppers

Kenneth,

The motor I ran tests on is a Sanyo Denki "Step-Syn" 103H7126, a 2A
per phase, 180 in-oz size 23 motor. The motor torque was:

0 to 2,500 full steps/sec (0 to 750RPM) 180 in-oz
5,000 full steps/sec (1,500RPM) 85 in-oz
10,000 full steps/sec (3,000RPM) 35 in-oz
20,000 full steps/sec (6,000RPM) 15 in-oz
No-load stall 34,000 full steps/sec (10,200RPM)

This motor is a "square" motor, not the older round motor. I assume
yours is a round one because I could find no data on Sanyo Denki site
for that number.
