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 ...

Monolithic power ICs that are physically small, inexpensive, practical, and programmable can replace the bulkier, less flexible and more expensive boards and boxes that provide microstepping ...

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 ...
