Electromagnetic Design & FEA Simulation
Computer-Aided Electromagnetic & Thermal Optimization
Before cutting silicon steel or drawing copper, every transformer design undergoes rigorous 3D Finite Element Analysis (FEA) to map magnetic flux distribution, leakage reactance, and electrodynamic short-circuit forces. This prevents hot-spots and ensures acoustic hum compliance.
