Hybrid Stepper Motor & Adafruit Motor

Post by hsi »

Hi,

I got DFRobot Hybrid Stepper Motor for 3D Printer (3.5kg) (https://www.dfrobot.com/product-785.html), Would it be able to work with Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit - v2.3? If so, how to connect it and to run it?

Thanks a lot.

Based on the specifications, the motor appears to be designed for use with a current-limiting 'chopper' type driver. The drivers on the shield do not have current limiting, so it would not work for that motor.

We do have the DRV8833 which would work, but would only be able to achieve about 2/3 the rated torque: https://www.adafruit.com/product/3297

www.pololu.com carries a wider selection of stepper drivers. This one would be a good match for your motor: https://www.pololu.com/product/2973

Thanks for the fast respond.

Out of curiosity, will the Bipolar Stepper Motor with Planet Gear Box https://www.dfrobot.com/product-1082.html works with Adafruit Motor

Unfortunately, no. That motor is also designed for use with current limiting drivers.

The main clue is the low phase resistance:
Resistance: 1.7±10% Ohm/Phase
Without current limiting, any reasonable supply voltage would overload both the driver and motor. A rough rule-of-thumb for compatibility with the shield is a phase resistance of 10 Ohms or more.
