Designers of motion control applications are under pressure to optimize performance and efficiency while keeping component count and space to an absolute minimum. The ideal situation is sensorless ...

Starting on Monday, September 19, and running through September 23, Design News will present the free course, DC Motor Controls with the RP2040 Pico. Each class runs an hour, beginning at 2:00 Eastern ...

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 ...

There are a lot of cheap Chinese CNC machines out there with okay mechanics and terrible electronics. The bearings aren’t complete crap, but the spindle of these CNC machines is a standalone PWM ...

Years ago my pal Steve Titus wanted to experiment with some drone rotor designs. He needed a simple motor controller that could operate from 8V to 12V and deliver amperes of current to a DC motor used ...

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 ...
