Automate motor winding with Arduino
When you want to make a mobile robot, DC motors can be a great choice. We normally accept that they can be purchased for a few dollars each, but what if you want to make your own?
In order to assist with the winding process for a self-built—or at least self-wound—motor, Mr. Innovative created an… innovative fixture with two stepper motors and an Arduino Nano for control.
The bare motor armature is held in a vertical orientation by one stepper, while the other winds wire using a hollow 3D-printed feeder mechanism. User interface consists of an OLED screen and buttons that let you select the number of windings and another to advance the armature to the next coil location.
