A synchronous motor runs at 600rpm, which of the following case is true?

P= 12, f = 50 Hz

P = 12, f = 60 Hz

P = 8, f = 50 Hz

P = 10, f = 60 Hz

P= 12, f = 50 Hz

P = 12, f = 60 Hz

P = 8, f = 50 Hz

P = 10, f = 60 Hz

Let T be the net torque developed by the rotor runs at ω rad/s. What is the mechanical power developed?

Pmech = (2πωT)/60

Pmech = (2πωT)

Pmech = (ωT)/60

Pmech = ωT

Pmech = (2πωT)/60

Pmech = (2πωT)

Pmech = (ωT)/60

Pmech = ωT
