Abstract
Polyphase permanent magnet synchronous motors are well suited for developping electromechanical actuation system showing a high level of reliability as they are able to run with a reduced number of phases and therefore allow to make the actuation system they are driving tolerant to the loss of feeding of one or more than one phase. The paper focuses on the way to determine for motors with any number of phases greater than 3 the optimal values of the phase currents allowing the motor to develop the needed torque in healthy and fault tolerant mode operation. It also assesses the oversizing imposed to the motor and the power electronics for maintaining the performance unchanged in fault tolerant mode operation.
