111 this paper. niaxinluni efficicnc!. operation of tu.0 t!.pcs of pcri~~ancnt magnct s! ~ichro~ious machine drives. namcl!.. surfacc tqc permamit magiict s!~~~clironous macliinc (SPMSM) and interior t! pc pcr~nancnt magnet s!mhronous machine (IPMSM). are invcst~gated. Thc cf-'ficicnc!. of both drives is iilasimized b! ni~nimizing cupper and iron losses. Loss minimization is implemented using flus \wakening. A neural net\vork controller (NNC) is designed for each drix. to ~cI~~c\c loss niini~iiization at difi'crent speeds and load torque valucs. Data lbr trainmg thc NNC arc obtained through off-line s~mulations of SPMSM and IPMSM at di;-Yerent operating conditions. A ccurac!. and fast response of cach NNC is po\.cd b!, appl!x~g sudden clianycs in spccd and ioad and tracking thc NhC output. Thc motors' efficiency obtained by flus ~\cakciiing is coinpared \~ith thc cfficicnc!. obtained whcn setting the d-axis current component to zero. \vliile varying tlie angle of ad\!ancc "cp" of the PWM invcrtcr suppl! ing tlic PMSM drivc.
