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, ...

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 ...

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 ...

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

This circuit regulates a DC power output. It has a very wide application range. It can be used to control the speed of a motor, a pump, a toy train, the brightness of a LED or lamp, etc. Practically, ...
