Oriental Motors has introduced sinewave drive vector controllers for its 30 and 50W brushless dc motors, improving speed tracking, reducing audible noise, increasing peak torque (15% for 30W types and ...

This circuit takes advantage of the voltage drop across bridge rectifier diodes to produce a 5-position variable voltage supply to a DC fan or other small DC motor. It is not as efficient as a ...

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, ...

Infineon has created a pair of motor controllers for small automotive electric motors. “The three-phase TLE995x for brushless dc motors is ideal for pumps and fans in thermal management systems, while ...

The last 20 years have seen precision amplifiers used for positioning and velocity control make major strides in power output, size, and control features. Applications such as laboratory automation, ...

The speed of a DC motor is directly proportional to the voltage applied across its terminals. The speed of a DC motor is directly proportional to the voltage applied across its terminals. This project ...
