Peak-torque performances of saturated and unsaturated asynchronous motors for high-dynamic electric drives

An analytical procedure for the evaluation of a feeding algorithm is sugges ted, which obtains peak-torque performances of asynchronous induction motor s fed by electric power converters. At the same time, it shows that the alg orithm envisaged represents an improved solution of the well known field-or iented control technique. The procedure is also applied to saturated machin es, because the peak-torque performance envisaged implies that traditionall y designed motors operate with air-gap flux densities higher than their rat ed values.
