The [Denki Otaku] YouTube channel took a look recently at some stepper motors, or ‘stepping motors’ as they’re called in Japanese. Using a 2-phase stepper motor as an example, the stepper motor is ...

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 are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.

The graph shows that at 16 microsteps/full step, the incremental torque for one microstep is less than 10% of the full-step holding torque. The lure of microstepping a two-phase stepper motor is ...

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.

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 ...

Microstepping is a major advancement in step motor technology introduced many years ago that allows motors to make finer steps in movement. By manipulating the current vector, microstepping creates ...

Innovations improving smoothness of motion, miniaturizing designs, and networking are still moving microstepping technology ahead 25 years after it provided a revolutionary solution for position ...

Find a downloadable version of this story in pdf format at the end of the story. Microstepping a two-phase stepper motor requires the winding currents to be 90° out-of- phase so that the stepper ...

IC has two-line Step and Direction interface and efficient DMOS output. Thomas Rowan, Allegro Microsystems, Worcester, Mass. Most microstepping motor drivers require control lines for DACs to set the ...
