Starting Position for the study was a compressor rotor in which a fast turning drive (180'000 rpm) with a maximum power of 1kW at 90'000 rpm was to be integrated. Different types of induction machines (synchronous motor, asynchronous motor, reluctance machine) were to be tested by a finite element computation concerning their feasibility. This study is based on the findings of the project work "Boosterantrieb" by M.Bachmann (2001). The aim of the study is to show the technical feasibility of electrical drives on the flow side of the compressor rotor. On the basis of the results a module will be built and tested in a test stand without any outer forces. Criteria therefore are: speed-torque characteristic and an additional moment of inertia. To solve the problem the field computation program Flux2D from the firm Cedrat was used. At first the type of motor should be specified. With this type the whole study will be carried out. In the project work of M.Bachmann (Boosterantrieb) the whole simulation was only done by asynchronous motors because they were regarded as suitable. As a continued study by Dr. R. Büchi proved this assumption, it was decided that the study should be done with the asynchronous motor with a squirrel cage. During the diploma thesis two completely different options crystallised as the right ones. Option 2d has 16 slots on the rotor. With this layout it was possible to reach a power of 600 Watt at 90'000 rpm. What remains uncertain is the mechanical stability. The second option 3f is driven by a rotor with a shrinked on aluminium ring. This motor can put out a power of 700 Watt at 90'000 rpm. Is also certain that this mechanical construction will resist the high speed of the rotor. Additionally this option has a minor inertia moment than option 2d. By comparing the torque, the power and the inertia moment the option 3f was better than 2d. Although this option does not reach the power of 1kW at 90'000 rpm it, seems that it should be built.
