Abstract: We propose a one-millimeter-scale linear ultrasonic motor and its feedback control system with a Hall sensor. The size of the stator measures 1.6 mm in height, 1.6 mm in width, and 0.3 mm in ...

Abstract: Permanent Magnet Synchronous Motors (PMSMs) have replaced DC motors in various applications due to their higher efficiency, compact size, and superior performance in dynamic environments.

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...

Scientists at Ames National Laboratory, in collaboration with Indranil Das's group at the Saha Institute of Nuclear Physics (India), have found a surprising electronic feature in transitional ...
