Hiroyuki Sano of JSOL discusses how using the company’s JMAG-RT modelling software module enables the simulation of FEA-based models in Real-Time; something that was previously not possible.

One of the most critical issues facing engineers conducting real-time simulation of hybrid drives is how to attain acceptable model accuracy with an achievable simulation time-step. While a simple Park two-axis model is usually sufficient to conduct most HIL tests, increased model precision may be required from time to time. For example, some PMSM drives have very high cogging torque levels, which cannot be easily ignored. In other cases, the engineer may desire accurate modeling of inductance variations.

Finite-Element Analysis (FEA) based real-time simulation resulting from the integration of JMAG-RT with RT-LAB addresses these issues. Because of JMAG-RT’s powerful code optimization and usage of lookup tables, real-time simulation of FEA-based PMSM drives can be conducted at time steps close to 20 microseconds on Intel CPUs.
