Variable reluctance (VR) sensors transform mechanical motion into electrical signals by exploiting changes in magnetic flux. As a ferromagnetic target moves past the sensor’s pole piece, the ...

Electromagnetic compatibility (EMC) is a crucial consideration in modern electrical engineering, particularly in the design and implementation of variable speed drive (VSD) systems. When EMC is not ...

ST. LOUIS — Copeland announced the launch of the KF variable-speed scroll compressor with EV4 variable frequency drive platform in North America. The KF is Copeland’s variable-speed scroll compressor ...

Texas drivers, prepare to go with the flow—literally. New variable speed signs are popping up across the state, changing speed limits in real time to keep traffic moving and accidents at bay.

The ride-hailing giant’s background check process was intended to speed drivers onto its network while keeping costs down, internal documents show. The ride-hailing giant’s background check process ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can reduce energy consumption by up to 30% on average—and as much as 80% in ...

October 2025 marks the 50th anniversary of the Low Voltage Variable Speed Drive (LV VSD), which was used in a commercial application for the first time at a sawmill in Finland, in 1975. It was ...

SIOUX FALLS, S.D. (Dakota News Now) - The South Dakota Department of Transportation is currently installing a new program where I-29 between Flandreau and Brookings will have variable speed limits.

Although there are substantial efficiency improvements to be gained through motor upgrades, even greater energy savings are possible when a high-efficiency motor is paired with a variable-speed drive.
