Abstract
The explanation related to the concept of Rotating Magnetic Field (RMF) in 3-phase induction motor (IM) and its visualization is a tricky issue in teaching–learning process. The complexity increases with the number of poles. Hence visualization of RMF for a 4-pole Induction motor is attempted via magnetic field distribution pattern(s). The aim of this paper is to explore and utilize the capability of Finite Element Method Magnetics (FEMM) as a tool for demonstrating rotating magnetic field effect produced in the stator of a 3-phase induction motor. In addition to the RMF demo, visual correlation between angular rotations of electrical wave with mechanical degree is reported. Also, the effect of phase sequence reversal is incorporated in the graphical exhibition.
