The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

DC motors come in many forms, but they all have the same job: turning electrical energy (DC) into mechanical energy. Although DC motors have a common operating principle, many applications—including ...

Allegro Microsystems, LLC releases a new high current integrated DC motor drive IC, the A5950. Allegro’s A5950 is designed for PWM control of DC motors and capable of peak output currents up to ±3 A.

Systems that have controlled parameters and closed-loop feedback mechanisms are generally more robust and less susceptible to failure. For example, vehicle engines regularly use temperature sensors ...

Brushless dc motors have the advantages of high reliability and smaller size, but the absence of brushes can pose challenges. One challenge is the requirement for electronic commutation and control, ...

This file type includes high resolution graphics and schematics when applicable. Bob Zollo, Product Planner, Power and Energy Division, Keysight Technologies Electric motors are prevalent in our ...

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 Racer series, ...

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...
