Motor Control Basic In this tutorial, a simple motor driver, dual-channel H-bridge is used. It allows control of bi-directional and variable speed of up to two motors. Note that this covers a specific ...

Circuit Diagram The circuit is connected in breadboard as per the DC motor speed control circuit diagram shown above. The pot here is used to adjust the speed of motor. The switch is to change the ...

Servo motors are commonly used in many embedded system applications. This tutorial explains how to test a servo motor using a simple 555 timer based servo tester circuit.

Many motor control circuits, even the very simple, include some motor overload protection features such as overcurrent motoring, temperature sensors, and voltage monitoring.

New Field-effect transistors and motor-control circuits offer better motor control Today's motors are increasingly driven via electronic controls, which offer better control of speed, position, and ...

Isolating problems in the control circuitIn Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic ...
