Stepper motors are brushless synchronous electric motors powered by direct current that rotate in steps, keeping the rotor stationary under a specific power supply. A well-defined sequence of PWM ...

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 ...

Abstract: Microstepping drive for stepper motor is a well-known technique to improve stepper motor performance. Normally microstepping is carried at fixed pulse width planned. But this method is ...

The A4979 is a flexible microstepping motor driver with built-in translator for easy operation. It is a single-chip solution, designed to operate bipolar stepper motors in full-, half-, quarter- and ...

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 ...

Motion Control Products Ltd is launching the DMD556 next-generation digital microstepping drive that is claimed to benefit from unprecedented audio noise reduction (by 70%) and smooth low-speed ...

const int dir_pin = 12 ; //defining pulse or direction pin( HIGH - clockwise) const int ena_pin = 2 ; //defining pulse or enable pin....HIGH means driver is off and rotor is free float ...

In theory, you really don’t need much to work with electronics. A scope ought to do everything. However, for special purposes, it is handy to have meters, logic analyzers, and other special-purpose ...
