Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

A simple, low-cost hardwired step per motor control circuit that can be used in low-power applications, such as moving toys etc is presented here. A simple, low-cost hardwired step per motor control ...

This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1). However, this idea integrates not only the driver, but also a simple one-axis stepper-motor ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...

Astrosyn International Technology is launching the MSST5-S stepper motor driver. The new driver is similar in price to traditional 5A step-and-direction microstepping drives, but offers three modes of ...

The fundamental circuit shown in Figure 1 generates timing for a two-phase stepper motor from an oscillator, as well as a direction (forward or reverse) signal. Figure 2 depicts the typical timing ...

Step motors provide accurate position control without the need for feedback, traditionally in open-loop control schemes. A stepper motor’s shaft normally makes discrete angular movements of ...
