Modelling a Rotor Bar of an Induction Motor for Improving Electromagnetic Torque and Efficiency Using Permeance–Based Equivalent Circuit Model and FEA

Induction machines (IMs) are attracting the automotive industries’ focus due to remunerative benefits striving researchers to improve electromagnetic performance characteristics. Enhancing the electromagnetic capabilities of an IM is a challenging task, given the obstacles posed by an elevated rotor copper loss which leads to a rise in rotor temperature, and a low torque density. This paper presents a permeance–based equivalent circuit model …
