Abstract: Switching-state phase shift (SSPS) method is widely used in motor drive system with single dc-link current sensor (SDLCS) because of its advantages such as no additional hardware design ...
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 ...
