“…High speed E-motor unbalance can be handled by preliminary simulation, like one described in (Hong, DK., et al 2013). The vibration sources of rotor in permanent magnet (PM) E-motor include mostly the centrifugal force generated by eccentricity and the unbalanced magnetic forces.…”

In this paper, an outlook about the present of electrical aviation is given. The relatively small energy density of current battery technologies is adequate to build usable electric car, but not suitable for electric aircraft. Because of the very limited amount of energy available on-board, a couple of percent in efficiency can give significant increase in range and flight time, hence the development of more efficient propulsion system and E-motor is as important as the development of battery technologies. Current research results at the University of Dunaujvaros show, that building E-motors from amorphous materials is possible, and can easily increase the efficiency of high speed E-motors.

This paper presents an analysis of the manufacturing technologies for the high-speed electrical machine with stator core made of amorphous magnetic material, their trends and perspective of development. The most efficient technology is determined. A design technology of sectional stator cores made of amorphous magnetic material is proposed. In addition, the paper shows the design methodology of the high-speed electrical machine with stator core made of amorphous magnetic material. A distinctive feature of the proposed technology is the implementation of the stator core made of amorphous magnetic material and laminated in the axial and radial directions. The fill factor for magnetic cores realized by this technology reaches 75%. The design methodology was tested on three prototypes of the high-speed electrical machine including the 120-kW prototype. The prototype experimental research is also presented in the paper. The main contribution is the loss minimization in the stator core made of amorphous magnetic material by 200%.

“…n recent years, high-speed permanent-magnet motors (HSPMMs) are gaining in popularity in industry due to their high power density, low weight and high efficiency [1]- [3]. They are employed in applications such as compressors, motor tools, gas turbines, flywheels, centrifuges, and vacuum pumps [4]- [6]. In conventional compressor systems, a gearbox is often used, which increases noise and reduces the system efficiency.…”

Electromagnetic design of a 1.12-MW, 18,000-rpm high-speed permanent-magnet motor (HSPMM) is carried out based on the analysis of pole number, stator slot number, rotor outer diameter, air gap length, permanent magnet (PM) material, thickness and pole arc. The no-load and full-load performance of the HSPMM is investigated in this paper by using 2-D finite element method (FEM). In addition, the power losses in the HSPMM including core loss, winding loss, rotor eddy current loss and air friction loss are predicted. Based on the analysis, a prototype motor is manufactured and experimentally tested to verify the machine design.
