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 ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

Electronic speed controller with arduino project illustrate a physical 3-phase motor driver system. It features high current MOSFETS, dual MOSFET drivers, and an arduino nano. A DIY motor driver board ...

Is it something in the water, or have there been a lot of really cool servo projects lately? Mechaduino is a board that sits on a regular stepper motor and turns it into a servo with a closed loop ...

A special closed-loop stepping-motor system eliminates difficulties around resonances and allows less-conservative motor sizing. • Clever management of motor current in a closed-loop stepper system ...
