Abstract: In this article, a high-speed flat wire permanent magnet (PM) motor is proposed for the potential application of electric vehicles (EVs), where the radial force and torque ripple are ...

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 ...
