In the industrial sectors characterized by a high technology competition, the rush for maximum performance results frequently in multi-objective optimization problems. For instance, most of the main car manufacturers regard Interior Permanent Magnet (IPM) motors as the best solution to address the tight design constraints which their Hybrid and Electric Vehicles have to meet. Finding the optimal rotor geometry of a high performance IPM motor involves several variables and has a significant influence on the overall characteristics of the motor.This paper proposes a novel magnetic model that enables the designer to define computationally-efficient fitness functions necessary to run an optimization algorithm. This model consists of a small set of recursive equations, so that its validity may be extended to an unlimited number of flux barriers. In order to validate this approach, the Lexus LS 600h motor (two flux barriers) has been selected as a case study.

Abstract
In the industrial sectors characterized by a high technology competition, the rush for maximum performance results frequently in multi-objective optimization problems. For instance, most of the main car manufacturers regard Interior Permanent Magnet (IPM) motors as the best solution to address the tight design constraints which their Hybrid and Electric Vehicles have to meet. Finding the optimal rotor geometry of a high performance IPM motor involves several variables and has a significant influence on the overall characteristics of the motor.This paper proposes a novel magnetic model that enables the designer to define computationally-efficient fitness functions necessary to run an optimization algorithm. This model consists of a small set of recursive equations, so that its validity may be extended to an unlimited number of flux barriers. In order to validate this approach, the Lexus LS 600h motor (two flux barriers) has been selected as a case study.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
