Sensitivity analysis and performance optimization of an industrial squirrel-cage induction motor used for a 150 HP floating pump

Performance optimization is usually an important issue in the design of industrial electric machines. In this paper, a 150 HP induction motor utilized in an industrial floating pump is analyzed and optimized for an enhanced efficiency, a higher power factor, reduced losses and an increased power to weight ratio. Also, two-dimensional time-stepping finite element method (2-D TSFEM) is employed in the survey. The geometrical parameters of the rotor and the stator as well as the winding configuration are those that are optimally designed. A significant matter concerned with the motor is the frame of the stator and the rotor shaft which both are made of a magnetic material in which the flux flow. Sensitivity of the design parameters on the device performance are also extracted and presented. Finally, based on the outcomes, the machine has been built whose experimental results confirm the design.
