Simcenter 3D 2406 Acoustics Simulation with Step Skew Electric Motors

Simcenter 3D 2406 introduces a new functionality for modeling multi-step skew motors in acoustics simulations. For Permanent Magnet Synchronous Motors force spikes occur due to the alignment of rotor magnetic fields and stator teeth/slots. To reduce the spike and the subsequent torque ripple it is common to step skew the rotor design. Such designs are easy to produce in Simcenter E-Machine Design and with the latest update you can import the multi slice force information into Simcenter 3D and distribute it to the full vibro acoustic model
