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 ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

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 ...

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.

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 ...

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 ...

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 ...
