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 = ωT

Pmech = (2πωT)

Pmech = (ωT)/60

Pmech = (2πωT)/60

Pmech = ωT

Pmech = (2πωT)

Pmech = (ωT)/60

Which of the following is the correct relation regarding coupled coils?

M > (L1L2)0.5

M ≤ (L1L2)0.5

M = (L1 − L2)/2

M = (L1 + L2)/2

M > (L1L2)0.5

M ≤ (L1L2)0.5

M = (L1 − L2)/2

M = (L1 + L2)/2
