An efficient torque speed characteristic calculation method for brusbless C.A.D using optimization techniques

Abstract

Nowadays, powerful tools enable to simulate the work of inverter fed machine systems. But, they generally require long calculation times and large memory capacities and many parameters, So, they are not well adapted for an iterative design. In this paper, we present an efficient model, based on optimization techniques, for current fed synchronous machines fed by means of current controlled voltage inverter which leads to very short calculation times to determine torque speed characteristic of such a actuator. The limits of the valitidy of this model are discussed and simulated results are compared to experimental ones for validation.
