I have thee new stepper motors they are SanyoDenki StepSyn 710.6 oz/in motors. The specs on them are as follows:
on the name plate here is the specs
12-375V
6A
stall torque 5.09 N.m
1.8DEG
I am also attaching a pdf drwaing of the motors which states rated output to be 2.1V. Could someone please tell me what size power supply i should be running these motors with i have three motors hooked up to 3 G202 Gecko drives and i will be hooking up a fourth axis but it appears that something is wrong with my setup as i have no torque the motors are stepped down 2.5:1 to the Lead screws i will be replacing them and going ballscrew eventually but for now i want to see why i have no Torque. I was told that the Tormach cnc's are running between 400-600 oz/in motors direct coupled and they run with lots of torque but it seems i can't get mine to take small cuts without the motors stalling. I have these motors at work also and when the machines at work are on you can't turn the motr spindle by hand but at home i can take my hand and turn the motor spindle with very little effort i would appreciate some help on this problem as you guys have a way better handle on this stuff than i do.
