“…The machine was already used in [5] to introduce the vibration synthesis based on force response superposition. In comparison, the recent advances become apparent, which are the integration with the system simulation [4] as well as the more efficient and advanced structural dynamics modeling and vibrations synthesis. Figure 7 compares a measured and a synthesized spectrogram of the structure-borne sound (surface normal velocity) of the PMSM traction drive.…”

“…Furthermore, analytical or measurement-based models can be used and radiated sound calculations or transfer path analyses be added. The presented modeling framework (see Figure 1 on the next page) combines a system simulation [4] and a vibration synthesis process [5]. It consists of automated offline-and userinteractive online-steps.…”

“…The drive is operated along an arbitrary torquespeed trajectory. Via the force model [4], the time variations of the air-gap force shapes are obtained. These are used in the subsequent vibration synthesis for scaling and superposing the normalized air-gap force responses.…”

This paper presents a universal acoustic modeling process for efficient, high-quality acoustic modeling of electrical drives. It combines the two fast and user-interactive steps system simulation and vibration synthesis. The underlying model parameters are obtained via automated offline finite-element simulations based on generic input parameters. This allows using complex electromagnetic and structural models without computation time becoming prohibitive. The approach can be applied to all types of machines, including outer rotor and transversal flux machines as well as machines with rotor or stator skew. Switching frequencies and spatial machine harmonics are routinely taken into account. Sound radiation or transfers path analyses can be added. Analytical or measured models can also be used. This makes it a universal acoustic modeling framework for electrical drives. Application examples are given for a permanent magnet synchronous machine traction drive for a hybrid electric vehicle as well as a for a switched reluctance auxiliary drive. Simulated run-up spectrograms for structure borne sound are validated against measurements and operational deflections are presented.

“…It is widely known that the magnetic force fields in the air-gap of electric machines contain not only fundamental sinusoidal waves, but also higher-order harmonic components both in time and space [19]. Some of the high-order harmonics are generated because the magnetic field in the air-gap is distorted due to the presence of nonlinearity even when the applied current is sinusoidal.…”
