It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...
Innovative Swedish boutique carmaker Koenigsegg has revealed a new 6-phase electric motor for its four-seat Gemera supercar that establishes new benchmarks for power density. The Dark Matter motor ...
Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...
Somewhere in most engineering educations, there’s a class on induction motors. Students learn about shaded-pole motors, two-phase and three-phase motors, squirrel cage motors, and DC-excited motors.
A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...
Novel bi-phase piezo motor enables accurate linear motion in an extremely compact package, new from PI. PI’s B-421 miniaturized piezo stages provide 10 nm positioning resolution in an extremely ...
ST’s EVLSERVO1, a turnkey reference platform for servo motor control, enables sensorless or sensored field-oriented control (FOC) with one, two, or three shunts. It drives three-phase brushless motors ...
