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: This article presents an improved rotor position estimation method for surface permanent magnet synchronous motor (SPMSM) using a low-resolution Hall-effect sensor. First, an observation ...
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 ...
Designed for EVs and HEVs, these current sensors deliver accurate, isolated measurement for batteries, motors, and safety critical protection circuits. As electric and hybrid vehicles adopt higher ...
