Hi,
I am not so familar with motor project, so I need some help to more understand my needs.
I need to motorized a running Wheel (for rats), for a project at the university. I have try with a stepper motor, but meet 2 problems:
1) Since I need to go very slow (< 1 rpm), the Wheel was rotating by step (even if I was going at 1/16 steps). My motor has 200 steps.
2) I was able to rotate the Wheel faster (or slower) than the speed specify with a little help of my hand (simulate a rat running in the Wheel).
Because of the problem #1, I figure I need to use DC motor. Is is true?
I think the problem #2 can be solve by using a bigger motor (more torque - the one I use is 177 oz-in). Is it true?
Also, if I use a DC motor with a speed controller, can I use any PWM speed controller (using correct Amp. and Volt specs) even if I run at a very low speed (< 1 rpm)?
I didn't have bought the DC motor and speed controller yet, but I looking for DC motor with less the 100 rpm and higher torque that the stepper motor that I have).
Thanks for any help
Marcel
