Have you ever wondered how a stepper motor worked? Like most things if you work through making it yourself, all your questions can be answered and more. With this in mind Instructables user ProtoG did just that and has documented their home-made stepper motor made from 3D-printed parts.
The motor is capable of 15 degree full steps, or 7.5 degree half steps in either direction, and is controlled via an Arduino or compatible board. Each coil can be controlled via an N-MOSFET which allows for easy Arduino connection – the MOSFETs can be neatly activated by a digital output pin. For a demonstration of the stepper motor, watch the following video:
To make your own, all the design files and information can be found on the motor’s Instructable page. And for more, we’re on facebook, twitter and Google+, so follow us for news and product updates as well.
If you’re looking into starting with Arduino and robotics, such as controlling a stepper motor (or DC motors) from your Arduino or compatible, check out our HBRIDGE: DC/stepper motor shield.
Based around the powerful Allegro A4954 H-bridge driver IC you can control two DC motors with complete ease, or one bipolar stepper motor. With connections for external power management, a complete beginners’ guide and documentation – motor control couldn’t be any easier. For more information and to order, visit the HBRIDGE: page.
