Stimulus of Magnetic Flux in the Surface Vicinity of Electric Motors on Human Health

Abstract

This work is carried out to understand flux distribution around induction motor and their influence on human health. High-capacity Squirrel Cage Induction Motor (SCIM) draws huge currents; hence, the colossal flux density is emitted around the motor. When the leakage flux interfere with high-frequency electromagnetic waves, the influence on a human being is more dominant than power frequency. Time domain Finite Element Analysis (FEA) is performed to get an accurate instant value of magnetic flux distribution in and around motor a 15kW, SCIM. A 3D human head is modelled using FEA and placed in the vicinity of magnetic leakage flux mixed with high-frequency electromagnetic waves. The simulation reveals that magnetic leakage flux from SCIM is harmful to humans. The main objective of this work is to identify safe regions and create awareness of magnetic leakage flux, which can cause human health problems.
