In this work an integrated model for acoustic evaluation of electric vehicles is introduced. The paper focuses on the force excitation part of the model. The analysis is performed for permanent magnet synchronous machines. The excitation forces are placed on the stator teeth and calculated for a structure dynamic model of the power train. A model for the acoustic emission is adapted and finally the...
A contactless energy transmission system is essential to supply onboard systems of electromagnetically levitated vehicles without physical contact to the guide rail. One of the possibilities to realise a contactless power supply (CPS) is by integrating the primary actuator into the guide rail of an electromagnetic guiding system (MGS). The secondary actuator is mounted on the elevator car. During...
The permanent magnet synchronous reluctance machine (PMSynRM) is a type of permanent magnet synchronous machine (PMSM) with the objective to provide high reluctance torque. This is realized by a particularly designed constellation of flux barriers in the rotor of the machine. Beside high efficiency and supplied power density, an acoustic evaluation of this machine is performed for various applications,...
