A three phase motor has the following technical specifications on its label: 7.5[kW], n=90.1%, cos=0.91, 2950 [RPM] If this motor is connected to VLL=400[V] 50[Hz] three phase grid, what are the powers listed below? What are the current it draws from grid and torque it generates at nominal speed? Real power: Pe= [W] Apparent power: S= [VA] Reactive power: Q= [VAR] Nominal power: Pn= [W] Mechanical power: Pm= [W] [A] Nominal current: In= Nominal torque: Tn= [Nm] A three phase motor has the following technical specifications on its label: 7.5[kW], n=90.1%, cos=0.91, 2950 [RPM] If this motor is connected to VLL=400[V] 50[Hz] three phase grid, what are the powers listed below?
