DC motors may not be the wave of the future, but they certainly have a secure place in today’s workplace (see DC Isn’t Dead). Therefore, it’s worthwhile for electrical professionals to take a look at ...

The DC motor is widely used in the field of servo automation and robotics. The operating principle of an electric motor is based on the interaction of two magnetic fields that attract and repel each ...

We often think of the electric light as being the “killer app” for electricity. Sure, the telegraph was also fairly important, but it didn’t enter every home the way the electric light did -- not ...

[Thinking Techie] takes us back to basics in a recent video explaining how magnets, coils, brushed DC motors, and brushless DC motors work. If this is on your “to learn” list, or you just want a ...

The design of different three-phase brushless DC motors and how they generate torque. How magnetics, construction, and other factors impact torque, speed, and smoothness in BLDC motors. General ...

How brushless DC motors use electronic commutation to maximize efficiency and ensure smooth and stable motion. Compare trapezoidal, sinusoidal, and sensorless commutation techniques, including key ...

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

“HW-687 is one easy module for adding speed regulation to your next DC motor-based project. It is a simple pulse-width–modulated speed controller providing smooth control with almost no jerks. There ...
