Optimization Procedure for IPM Motors by Changing the Rotor Structure

The paper has developed an optimization procedure to design the rotor lamination and magnetic sizes. average torque is improved by changing thickness of outer bridge width. Various metamodels with best prediction performance generated for each multi-objective functions constraints have been selected. By applying a genetic algorithm, several optimal solutions be considered compare those initial model. Hence, method designing interior permanent magnet (IPM) motor presented obtain high reliability maximum torque. This development allows estimate back electromotive force (EMF), flux density electromagnetic In addition, ripple evaluated via analytical Matlab program coupled finite element algorithm optimization. Rotor laminations are finally stamped assembled into verify EMF under rated load no test.
