Easy To Build Stepper Controller from a Recycled Materials. Open Stepper Project - Hacked Gadgets - DIY Tech Blog. Carl Erickson from Phenostream has built a very small yet very smart stepper motor. Many of them can be controlled via a daisy chained serial connection which could make it simple to interface with complex projects. This car project is a cool example of the possibilities. "The OpenStepper Module (OSM) is comprised of a GSM_01 and the OpenStepper circuit board.
OSM firmware is based on Mike Thompson’s popular OpenServo project which Jay Ragsdale was kind enough to port to the ATtiny84. " Jones on Stepping Motors. Index Abstract This tutorial covers the basic principles of stepping motors and stepping motor control systems, including both the physics of steppers, the electronics of the basic control systems, and software architectures appropriate for motor control.
Introduction Stepping motors can be viewed as electric motors without commutators. For some applications, there is a choice between using servomotors and stepping motors. In making a choice between steppers and servos, a number of issues must be considered; which of these will matter depends on the application. Stepping motors can be used in simple open-loop control systems; these are generally adequate for systems that operate at low accelerations with static loads, but closed loop control may be essential for high accelerations, particularly if they involve variable loads.
Stepping motors are known in German as Schrittmotoren, in French as moteurs pas à pas, and in Spanish as motor paso a paso. Other Sources of Information Web Sites Books.
