Bipolar stepper motors


Unipolar stepper motors are easy to control at the cost of low efficiency and power. Bipolar stepper motors have much higher efficiency and torque; however they are much harder to control. To fully control one, two H-bridges are required. Luckily there are multiple Arduino-compatible bipolar stepper drivers out there. Here we will explore a few options.

Getting ready

We can control a bipolar stepper motor using the Arduino Motor Shield. Here are the ingredients needed for this recipe:

  • An Arduino board connected to a computer via USB

  • An Arduino Motor Shield

  • A bipolar stepper motor

How to do it…

We connect the stepper motor to the shield using the following steps:

  1. Carefully mount the Arduino Motor Shield on top of the Arduino. Be careful not to bend any pins.

  2. Identify the two coils. Use a multimeter to measure the resistance between all the wires. The ones with a low resistance in between are the coils.

  3. Connect the four stepper wires to the main terminal output of the Shield....
