RawP-OPT - optimized SyR machine model
Abstract
Motor model to be used in SyR-e of the RawP-OPT motor, a synchronous reluctance machine with optimized rotor for increased torque and reduced torque ripple. 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.
