Stepper Motor (RB-Phi-267) Vibration Help

Help & Support Robot Parts

Hello,

I have a NEMA 17 Bipolar Stepper Motor rated for 12V, 1.7 Amps, 667 oz-in, and has a 100:1 gear ratio (Product Code: RB-Phi-267)[highlight=#ffffff][font=Helvetica Neue, Helvetica, Arial, sans-serif][/font][/highlight]. I am using a 12V 2Amp (MAX) power supply and an Arduino Uno with Adafruit Motorshield v2.3 for control. I am having issues overcoming the inertial effects of the stepper motor. When I send a simple signal for the motor to move 100 steps or so (1 degree) it vibrates violently and makes really loud noises. I am using the microstepping command to reduce the noise and make smoother motions. When i take the gear box off of the stepper motor the motor moves fine. Is there any suggestions out there for this application? Anything helps!

Thanks!

Hi,

Does the driver chip of the [Motor Shield Kit for Arduino v2.3](Motor Shield Kit for Arduino v2.3) gets hot when the stepper rotates ?
The RB-Phi-267 with the 100:1 gearbox consumes about 1.7A. The Motor Shield Kit for Arduino v2.3 can only provide 1.2A per channel and 3A for 20ms peak.
Without the gearbox, the stepper will consume less current because it’s providing less torque. This would explain why the stepper works properly without the gearbox.
Try to use, for example, this Pololu 8-35V 2A Single Bipolar Stepper Motor Driver
