Simulation approach
Electromagnetic field: ANSYS Maxwell runs 2D/3D EM simulation, computing torque, back-EMF, flux distribution and cogging torque to assess power density and torque ripple.
Loss & efficiency: decompose copper, iron and eddy/hysteresis losses, plotting an efficiency MAP across the full speed-torque range to locate high-efficiency zones.
Multiphysics coupling: EM loss feeds ANSYS thermal analysis, and EM force excites Mechanical to solve electromagnetic vibration and noise (NVH) — a closed EM-thermal-structural loop.
Value
Optimizes efficiency, torque ripple, temperature rise and EM noise before prototyping, cutting winding and magnetic-circuit trial rounds and shortening motor development.
For EV drive motors, industrial servos and generators, it builds a reusable EM multiphysics workflow supporting high-efficiency, high-power-density design.
Extended capability
The same EM simulation system also covers antenna & RF (HFSS), power electronics and EMC/EMI, providing device-to-system EM solutions for communications, electronics and electrical equipment.
