Description

Doctoral Thesis / Dissertation from the year 2010 in the subject Electrotechnology, grade: 1, Swiss Federal Institute of Technology Zurich (Power Electronic Systems Laboratory (PES)), language: English, abstract: In recent years, the demand for ultra-clean process environments for spin processes in high-purity industry branches, such as pharmaceutical, biotechnology and semiconductor industries has been growing. In these industries small particles generated through lubricants and wear in the bearings can damage the processed structures. The implementation of magnetically levitated motors in these application fields offers the advantage of a contactless and wearless operation. Furthermore, due to the fully circumferential air gap of such motors, a process chamber can be inserted into the air gap that creates a completely encapsulated space. In this space process dependent conditions, such as pressure, temperature, humidity can be provided locally and cost efficiently. A high acceleration capability of the motor is crucial for these processes in order to keep the process times low and increase the equipment throughput. Additionally, the achievement of high rotation speeds in the order of several thousand revolutions per minute is demanded by the processes. In this thesis, the conception, design and optimization of a magnetically levitated slice-shaped motor, that fulfills the industry's demand for high acceleration capability and high achievable rotation speeds is presented. Additionally, a high purity environment is ensured through an air gap large enough to accommodate a mechanically stable process chamber wall. The slice motor, which features a small motor height compared to its diameter, allows a very high level of compactness. The motor is implemented with a homopolar magnetic bearing and the permanent magnet synchronous drive on two circumferentially and axially shifted levels, giving the motor its name: 'Magnetically Levitated 2-Level Motor (M2M)'. Through the resulting magnetic decoupling, the drive unit can be designed independent from the bearing unit, aiming for maximum acceleration capability and maximum achievable rotation speed.
