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 ...

Using a rotation tester when installing a motor saves time and prevents problems such as driving the load backward. In some cases, you must get the motor rotation correct or massive damage will occur.

Driving a stepper motor can be a daunting task. Whereas, providing a voltage at the terminals of a DC motor causes immediate rotation, on a stepper motor, careful magnetic field commutation must be ...

Stepper motors exhibit a special feature: the ability to rotate the rotor shaft by a few degrees very precisely and without the need for sensors to detect the shaft’s angular position. In short, a ...

Rotary motor motion is usually converted to linear through rack and pinion sets, belts and pulleys, and other mechanical linkages. These are effective but limited systems. In contrast, integrated ...

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 ...
