A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

The PS211 Size-11 stepper motor achieves a nanospeed rate compliant to 2-Phase Nano Stepper Technology. The PS211 Series reaches up to 200,000 steps/rev at a fine-pitch resolution angle of 0.0018 in.

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.

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 ...

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 ...

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 ...
