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 ...

The compact and rugged unit for bipolar two-phase stepper motors can operate with motor coil currents of 0.7 A up to 7 A RMS (9.8 A peak) and voltages of 15 V to max 75 V. Parameterisation requires no ...

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 ...

Agile Systems has received a patent for technology designed to improve stepper-motor performance. It allows simple low-cost two-phase stepper motors to operate as sophisticated servo motors without ...

Precision movement and positioning systems used in industries such as automated manufacturing using the advanced single-chip digital motion controllers announced by STMicroelectronics. The two cSPIN ...

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.

3D scanners aren’t cheap, and the last thing you want to see after purchasing one is bad data. But that’s what [Dave Does] and others were getting from their Revopoint POP scanners until some communal ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...
