My CNC is built from 2 DC servo motors for X, Y axis and 1 stepper motor for Z axis.” Watch this video on YouTube . “Motor voltage: 24 VDC, 38 VDC (E-type).

The motors are driven with a stack of motor driver shields on top of an Arduino Uno, which uses Firmata to receive instructions over serial from a Node.js app using the Johnny-Five library.

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Race… ...

So long as the 0V rail is connected to the Arduino 0V rail, the positive rail can be any dc voltage – more or less that the Arduino, so great for 12V motors. And it is compatible with both 5V and 3V ...

Infineon has released a family of H-bridge driver ICs for small brushed dc motors in vehicles, that include hardware for ISO26262-level functional safety ... To support design, there are simulation ...
