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 ...
This project was carried out at Overview Ltd., a London company which specialises in high precision video-surveillance equipment. Overview produces devices that include a camera driven by two stepper motors, and an image-processing unit. Magnetic encoders ...
The Inertia Wheel Assembly (IWA) is composed by the IWA motor, the inertia wheel and the command electronics. IWA belongs to the Attitude Determination and Control System (ADCS) of the SwissCube satellite. Swisscube is a pico-satellite that complies with C ...
Initially, linear motors have been particularly dedicated to transportation systems. Nowadays, linear motors are meant to replace a system using a rotating motor and a transmission to realize a linear movement. With linear motors the performances increase ...
The presence of oil in domestic heat pumps is a hindrance, particularly for enhanced surface evaporators and for advanced concepts based on two-stage cycles. Very compact oil-free dynamic compressor directly driven by high speed electric motors and support ...
In order to create a new solar aircraft totally powered by the sun, a new method able to handle such a complex system must be developed. The project aim is to make a round-the-world flight in so as to promote the sustainable development. The aircraft power ...
The aim of this project is the design and the optimization of the electrical motors used in the Continuously Variable Transmission (CVT) system currently under development at JTEKT, an automotive part supplier company. Two motors are needed for the control ...
Ultrasonic motors have received much attention these last years, in particular with regard to their modeling and their design principle. Their operating principle is based on piezoelectric ceramics that convert electrical energy into mechanical energy in t ...
The paper presents a simplified analytical method to design a small two-pole slotless brushless dc motor. Using only a few approximations, the motor analytical model is formulated to generate a system of equations. The system can be solved analytically, pr ...
