Piezoelectric ultrasonic motors are superior to electromagnetic micromotors, because their efficiency remains theoretically constant during miniaturization. However, the still relatively recent technology has a considerable unexploited optimization potenti ...

Ultrasonic Motors are drive systems used in a lot of industrial applications notably because of their advantages i.e. no audible noise, compact size and fast response. Therefore, this technology has been chosen for the design of a new type of actuator for ...
MMS design allowing to move several cabins vertically, without counterweights. The vertical motion is performed with linear synchronous motors having stators distributed along the shafts and supplied by sectors. A simplified analytic approach developped at ...
An important issue in nanoelectromechanical systems is developing small electrically driven motors. We report on an artificial nanofabricated motor in which one short carbon nanotube moves relative to another coaxial nanotube. A cargo is attached to an abl ...
The paper reports the results of an experimental investigation of a five-phase two-motor drive system, consisting of a parallel connection of two induction machines (IM). Thanks to an appropriate connection of the motors, two machines are controlled indepe ...
Training for colonoscopy, which is the examination and treatment of the colon, is often performed on real patients once the physician has passed the novice level. This increases the risk to the patient and lengthens the procedure time. Since a decade ago, ...
This article presents the modeling, simulation, and practical application of a double-fed asynchronous motor-generator for pumped-storage plants equipped with a three-level VSI cascade. The problem of DC unbalance control is studied in this particular appl ...
Recent research has shown that it is possible to independently control two three-phase induction machines while supplying them via a single five-leg voltage source inverter (VSI). In such a two-motor drive system one phase of each motor is connected to a c ...
Synchronous motors require sensors in order to control these devices in speed and/or position. Basically, the auto-commutation needs 3 sensors for a 3-phase type actuator. In micro-motors, as there is no more room to place the sensors, self-sensing approac ...
