ABSTRACT

In this paper, optimal design of three phase squirrel cage induction motor to improve efficiency and power factor and to reduce total loss for variable load application is proposed. It has compared conventional and optimally designed same rating of 3hp (2.2kW) motor. The motor is designed and optimization using mathematically and the simulation results are presented. The mathematically equation is used for optimization and five objective functions namely Stator Copper Loss, Rotor Copper Loss, Stator Iron Losses, Efficiency, and Power Factor are considered. The importance of this work is highlighted by the recent concerns about the need to achieve energy savings in the industry and in the territory sectors. The motor design procedure consists of a system of non-linear equations, which imposes induction motor characteristics and motor performance. This is very useful to optimize the power factor, losses and efficiency of the induction motors.
