Ultra-High-Speed miniaturized motor

CTI project in collaboration with a Swiss industrial partner

Project description

Increasing the rotational speed of a motor allows reducing its size while keeping the same mechanical power. The idea of this project is to develop a miniaturized very-high speed motor running at 500’000 rpm for medical applications. Therefore, the motor must operate in environmentally harsh conditions (oxygen-enriched atmosphere, successive sterilization cycles, etc.). In addition, a lot of special mechanical and electrical constraints are encountered at such speed and reducing the heating is crucial when scaling down the size of motors. To reach the objective, high-tech materials are used and a Sensorless control will be carried out.
