I'm building a machine that uses a single stepper motor connected to a gearbox. I'm running it at full steps and I seem to only be able to reach 1000 steps per second with a 200 step/rev motor. Much higher and it stalls and makes a lot of bad noise. I really would like to be going at least 2000 steps.
Here's some specifics on the hardware:
- Machine originally used 3700 rpm, 12vdc 0.144hp motor.
- Stepper is 1200 oz-in wired bipolar parallel: http://www.automationtechnologiesinc.com/products-page/stepper-motors/nema-34-high-torque-stepper-motor-1200-oz-in-half-inc-single-shaft-with-flat
- Geckodrive G201x set at 6 amp.
- 600w 12v voltage booster. Tried setting output to 36v, 60v, and 80v but same results.
- Controlled by Arduino Uno clone
The original machine used a pulley between the motor and gearbox. Because I don't want slippage, I've switched to a gear and chain setup, but I think the gear ratio is reasonably similar. I had hoped that this stepper was powerful enough to replace the original DC motor, but it doesn't seem to be able to run quite as fast. Did I pick the wrong stepper?
On a related note, is there any way to do a comparison between a stepper and a regular old DC motor? Or is that comparing apples to oranges?
