But not correctly, the motor is powered from the 5V supply which is only good for low speed/load. Also, this trick will not work when powering from 12V. Report comment ...

Maxon Precision Motor's newly released DC servo motor controller, the ESCON 50/5 OEM module. This mini OEM plug in module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that ...

The HC4040 provides a 7.2-MHz clock to CT0 and triggers CT0 at 28 kHz (7.2 MHz/256). The result is a variable-duty-factor PWM waveform at CT0's output (O 0).Q 1 and Q 2 buffer and boost the waveform ...

This, in turn, determines the speed of a dc motor. For accurate speed control, a tachometer connected to the motor shaft sends a voltage signal back to the controller (drive).
