100-kW High-Speed Electric Motor for the Air Conditioning System of More Electric Aircrafts

The paper presents a design and mechanical analysis of a 100-kW high-speed electric motor with a stator core made of amorphous magnetic material for the air conditioning system of more electric aircrafts. Evaluation of critical rotational speeds and rotor mechanical stresses are reported. Experimental research has been made at a rotational speed range of 10000-60000 rpm accompanied with the rotor vibration measurements. During the tests, special attention was paid on assessing the critical rotational speeds. The paper will be useful to researchers and engineers working in the field of aircraft electrical machines and high-speed electric machines.
