As systems become more electrified, designers are required to ensure compliance of electric drive systems in terms of electromagnetic, thermal, noise, vibration, and structural analysis. Simcenter integrated motor design and system analysis solutions are well positioned to meet these needs. An integrated workflow allows designers to be more decisive from the start, compressing the overall design cycle.

 

1D electric machine models are indispensable in electric-drive system analysis and emulators. They are used to validate real-time controllers (SIL, HIL, and PHIL), without the need of a physical machine, or when it is under prototype. This is a flexible and cost-effective way of testing electric-drives without investing in rotating machines and dynamometers.

 

The model fidelity is design-stage dependent. For instance, in the initial sizing of the system, the goal is to ensure that the components meet the global steady-state performance and energy requirements. Hence, fast simpler models are used. Reliability virtual testing such as fault analysis and controller design necessitates more accurate models.

To support the flexibility in model export, the new release of Simcenter Motorsolve V6.3 as explained in this webinar, supports four types of exports to Simcenter Amesim (see Figure 1):

  1. Functional model (Static): A simple quasi-static model that is well suited for power budget or energy management in pre-sizing or validation.
  2. Equivalent Electric Circuit (Quasi-static): A simple linear model that is typically used in controls development.
  3. Equivalent Electric Circuit (Dynamic): A non-linear model that gives more insight into the motor behavior under high currents or fault conditions.
  4. Equivalent Electric Circuit (Dynamic-Spatial): A non-linear model that includes spatial effects such as slots and rotor. It allows torsional vibration analysis and winding current distortions. It is also invaluable in controller validation.

The following video demos this integrated workflow between motor design and system-level mechatronics analysis, that is, Simcenter Motorsolve V6.3 and Simcenter Amesim. Hence, designers can evaluate whether the electric machine meets the system’s design requirements, within the specified operating conditions.

These automated export options ease the workflow for Simcenter Amesim users, by getting rid of the burden required to design, analyze and export electric machine 1D models.

 

Simcenter Motorsolve is part of the unified Simcenter low-frequency electromagnetic solutions for electric machine design and analysis that also includes Simcenter MAGNET and Simcenter SPEED.
