Using JMAG RT model for simulating DMD in EESMs
Electromagnetics
PRESENTER:
Ricky Chien
EXPERTISE:
Electromagnetics
Software:
JMAG
This presentation outlines the application of the JMAG RT model in simulating Dynamic Motor Drive (DMD) technology for Enhanced Efficiency Synchronous Motors (EESMs). DMD, integrated with Field-Oriented Control (FOC) and a simplified inverter model, demonstrates up to 3% energy savings by imperceptibly modulating motor torque during real-world drive cycles. The methodology combines high-fidelity co-simulations using GT-Suite and JMAG-RT for drive cycle analysis with iron loss computations through hybrid real-time and finite element analysis (RT+FEA). Results from dyno testing and simulations validate significant reductions in battery energy consumption and motor losses, highlighting the effectiveness of DMD in advancing electric vehicle efficiency.
