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 ...

Adjust the phase current, crank up the microstepping, and forget about it — that’s what most people want out of a stepper motor driver IC. Although they power most of our CNC machines and 3D printers, ...

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 ...

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 ...

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 ...

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 maximum efficiency, the boundary conditions of the complete electro-mechanical system should be mapped During the optimization of a stepper-motor-based motion control system design an engineer ...

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 ...

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 ...

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.
