Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines. Most stepper motors ...

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 ...

Step motors are a natural choice when design specs call for low-cost automation with accurate, open-loop control. But finding the right stepper for a given application can be a challenge. There’s a ...

For the last 40 years, stepper motors have been used in applications requiring tight position control at an affordable price. The advantageous economics stem from simplicity. Steppers deliver accurate ...

Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on a ...

Most 3D printers use stepper motors to control the movement of the extruder head. If you could actually print those motors it would be one more big step toward self-replicating hardware. Now obviously ...

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 ...

Increasingly elaborate Rube Goldberg schemes for controlling step-motors have developed over the years that try to pace stepping to avoid missteps. This direction of development is fundamentally ...

The Series H42S high-torque, 42-mm. hybrid step motor has improved performance and competitive pricing. The 1.8 deg. step motors--measuring 42 mm. square--are available in four lengths: 25, 34, 40 and ...

Sometimes less is more. Here, a quarter-step switching logic sequence for stepper motors offers several significant advantages over full-and halfstep modes—higher resolution, smoother drive, minimal ...
