Self-sensing methods to drive micro-machines

Yves Perriard, Omar Scaglione, Jan Persson

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 ...

SwissCube inertia wheel assembly – mechanical part

The goal of this project is to develop and build an electric motor to drive the inertia wheel of the SwissCube satellite. This system should provide angular stability to the satellite and allow its control. The operational speeds range from 5000 to 11 000 ...

A two-motor centre-driven winder drive fed by a five-leg voltage source inverter

Drazen Dujic

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 ...

Optimization of a Single Phase Ultrasonic Linear Motor

Yves Perriard, José Fernandez Lopez, Markus Flückiger

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 ...

Quadrotor Using Minimal Sensing For Autonomous Indoor Flight

Dario Floreano, Jean-Christophe Zufferey, Timothy Stirling, James Roberts

This paper presents a Miniature Aerial Vehicle (MAV) capable of hands-off autonomous operation within indoor environments. Our prototype is a Quadrotor weighing approximately 600g, with a diameter of 550mm, which carries the necessary electronics for stabi ...

A Five-Phase Two-Motor Centre-Driven Winder with Series-Connected Motors

Drazen Dujic

Application of power electronics in variable speed electric drives enables utilization of ac machines with a phase number higher than three. It then becomes possible to use the additional degrees of freedom, available in multi-phase systems, to control oth ...

A Haptic Knob with a Hybrid Ultrasonic Motor and Powder Clutch Actuator

Hannes Bleuler, Dominique Chapuis, Etienne Burdet, Xavier Michel

In haptics, the forces to be displayed vary widely in terms of magnitude and bandwidth. A single actuator can hardly comply with these requirements. It has thus been proposed to combine electrical motors and passive devices in a hybrid actuator to cover a ...

A Novel Five-leg Inverter PWM Technique for Two-Motor Centre-Driven Winders

Drazen Dujic

Two three-phase motors can be controlled independently using a five-leg inverter as the supply, with one leg being common to both machines. Major shortcoming of this topology for general applications is the need to double the DC bus voltage in order to ach ...

Mental rotation of body parts and non-corporeal objects in patients with idiopathic cervical dystonia

Silvio Ionta

Mental rotation of body parts is performed through inner simulation of actual movements, and is likely to rely upon cortical and subcortical systems (e.g. motor and premotor areas and basal ganglia) involved in motor planning and execution. Studies indicat ...
