A simulation of an electric machine considering the coupling of rotor‐ and electrodynamics [PDF]
AbstractIn this paper, a method is presented to determine the vibrational behavior of an electric motor and the associated structure. Therefore, a holistic simulation approach is used, which takes into account the mutual influence of structural mechanics and electrodynamics.

Mathematical modeling of rheostat-reactor start of wound-rotor induction motors
Introduction. Wound-rotor induction motors are less common compared squirrel-cage induction motors. However, they occupy a significant share among electric drives with difficult starting conditions.

Electrical Machine Rotor Shielding for Low Cost Electrical Drive [PDF]
Electrical machine rotor shielding has been proposed for high-speed electrical machines, i.e., ≥50krpm, where a smooth current waveform becomes difficult and costly to generate due to the required high switching frequency. The rotor shielding is used to suppress the unsynchronized low order high amplitude current harmonics and consequently reduces the ...

Generator configuration for helicopter quadruplex electric tail rotor [PDF]
With the move to more electric aircraft (MEA), a key area of investigation is the development of commercially viable systems which are reliable, efficient, low mass, and are compatible and commensurate with the power and multiplex requirements of current and future aircraft.

Magnetic noise reduction of in-wheel permanent magnet synchronous motors for light-duty electric vehicles [PDF]
This paper presents study of a multi-slice subdomain model (MS-SDM) for persistent low-frequency sound, in a wheel hub-mounted permanent magnet synchronous motor (WHM-PMSM) with a fractional-slot non-overlapping concentrated winding for a light-duty ...
