RawP-FBS - asymmetric SyR machine model
Abstract
Motor model to be used in SyR-e of the RawP-FBS motor, a synchronous reluctance machine designed with analytical model and with asymmetric rotor poles (FBS=Flux Barrier Shift) for torque ripple reduction. Tested at PEIC laboratories and developed during a cooperation between Politecnico di Torino, Università di Modena e Reggio Emilia and Raw Power s.r.l.
