What Is Harmonic Magnetic Analysis?
Harmonic magnetic analysis calculates the effects of alternating current (AC) or voltage excitation in electromagnetic devices and moving conductors. These effects include: • Eddy currents • Skin effects (eddy currents in current conductors carrying an impressed current) • Power loss due to eddy currents • Forces and torque • Impedance and inductance. Typical applications for harmonic analysis are transformers, induction machines, eddy-current braking systems, and most other electromagnetic devices that work on AC. Permanent magnets are not permitted in a harmonic analysis. Material hysteresis effects are neglected.
