| Abstract |
In the design of induction motor adjustable-speed drives, the same efficiency and performance requirements can be achieved with different choices as far as the motor and the inverter individual size is concerned. Depending on the specific functions that relate motor and inverter size to their respective cost, each choice is expected to result in a different overall drive cost. This paper presents a design algorithm that enables to dimension the motor and the inverter so as to achieve a minimum of the overall drive cost, under efficiency and performance constraints. As a study case, the algorithm is applied to the optimal dimensioning of a 600 kW induction motor drive designed to operate over a 600÷1000 rpm speed-range with a 235\% temporary overload capability and a minimum motor efficiency of 94\% at 600 rpm and 600 kW. |
