Electric Motor Design
The goal is to optimize the design of an industrial three-phase induction motor (7.5 KW) used for industrial lifts and hoists.
The objective is to improve the performance of the motor by acting on a number of variables that define the shape and size of the rotor and stator and the windings in the stator slots, while simultaneously taking into account several factors: cost of construction, energy efficiency, power factor, and start-up current.
Given a configuration, we calculate the performance of the motor using finite element simulation software. Through a purpose-developed interface, the simulator is embedded within a multi-objective optimization procedure. The optimizer takes into account all performances simultaneously arriving at a set of optimal solutions.
Results and Benefits
Multi-objective optimization allows to propose different engine designs that represent the best tradeoffs between constraints and performance.
