Greetings all,
I'm working on a project where, for cost reasons, we've decided to use a stepper instead of a servo on the second system. The positioning is not critical, I'm moving to limit switches.
I'm checking my math.
On the servo I have:
1.5 A phase current while moving under full load
0.9 amps phase current while holding
Torque constant is 0.19 Newton-Meters
0.9 A* 0.19 Kt = 0.171 nM holding torque, or 24.2 ounce-inches.
1.5 A * 0.19 Kt = 0.285 nM load torque, or 40.4 ounce-inches.
(Thanks to www.unitconversion.org for their useful site)
Seems like the plucky STP-MTR-17048 from Automation Direct (83 oz-in, 2.0 A phase current) should have plenty of chutzpah to do the job.
Am I missing anything here?
Thanks,
TM
