Simcenter Motorsolve introduces a new force harmonics analysis that characterizes the electromagnetics force in terms of time and space harmonics (wavenumber-frequency domain). However, is a detailed NVH analysis always necessary? Or is there another way to gain insight into the dominant electromagnetic force harmonics that will excite a motor’s mode shapes, causing noise and vibration? To assess noise issues, the compatibility between the mode shapes and the force excitation is crucial.

Multi-domain & multiphysics verification analysis: thermal, NVH, structural integrityĪs a result, Simcenter Motorsolve 2021.2 supports several new end-windings for export and subsequent analysis in Simcenter MAGNET:Ī motor with a formed winding is first created in Simcenter Motorsolve (left) then imported into Simcenter MAGNET (right) for further analysis Force Harmonics Analysis.

Proper prediction of coil winding end effects, including electromagnetic forces.

Capturing the impact of rotational eccentricity.

Simcenter Motorsolve approximates this in 2D in-depth understanding of skewing effects requires a full 3D model So, what does the extra depth that 3D includes for which 2D cannot adequately handle? This level of modelling is usually sufficient when designing radial-flux electric machines however, full 3D modelling and FEA are essential for further detailed analysis.

The electromagnetic analysis in Simcenter Motorsolve is based on 2D FEA.
