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 ...

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 ...

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 ...

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 ...

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 ...
