Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position control is necessary. Motors of ...

First, we want to explain how such a controller works and what’s involved. A bipolar motor has two windings, and thus four leads. Each winding can carry a positive current, a negative current or no ...

Stepper motors are now being used more frequently in industrial environments. Increased performance and reduced size make them increasingly attractive, and their application is no longer limited to ...

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 ...

In this EDN Magazine article, K. Suresh of the Indira Gandhi Centre for Atomic Research describes a multiple-stepper-motor-control circuit that uses an ADC to control multiple stepper motors. The ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...

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 ...

For the PDF version of this article, click here. Consumer appliance and industrial applications are generating demand for sophisticated motor control circuits that can simplify system designs, reduce ...

A front panel lets operators control rotation direction, speed, position, operating mode, stop time, and homing. Motion profiles can run a set number of times or indefinitely. The checker also ...

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 ...
