This article explains how to create a brushed DC motor programmable speed regulator that is low-noise, high-performance, and affordable. The regulator is not affected by changes in temperature, ...

“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 ...

According to the accession file, the Ford Instrument Company built this device “to control motor speed on a time line.” It reportedly was used on early Mark VIII range keepers, built for the U.S. Navy ...

The output ripple of a standard isolated dc-dc converter is between 0.5% and 1% of its nominal output voltage. For applications requiring a lower output ripple, linear voltage regulators can reduce a ...
