Driving MOTS1 with Arduino

Modules Microcontroller Programmer - Experimenting Project
1

Hello,

I’m interested in running the stepper motor, MOTS1, which is a 12V DC/32mA (angle 5.625 degrees/64 steps) stepper motor with five wires, from an Arduino Uno.

Two questions:

  1. There are five wires and I’d like to know which wires are for which input/output and which are power and ground. I wasn’t able to figure it out from the documentation on Velleman website: http://www.vellemanusa.com/products/view/?id=351245.

  2. Is it possible to hook this up directly to the arduino (with external power supply) without a driver? I’ve only found one example of this online and they were using a super small motor that was powered from the arduino, so it’s a different type of project…

Thank you,
JBot

You will need a stepper driver shield, such as our KA03 to drive this motor, you cannot drive it directly from the I/O’s of the Arduino.
Here you can find some info regarding the pinout of different kinds of stepper motors. MOTS1 is a 4+1 wire type.
