How can we calculate No load and full load torque of electrical machines, i.e. motor or alternator..

Answer / shoebullah

T= k*sf*R2*E2^2/
R2^2+sf^2*X2^2

Where E2 is induce rotor emf,
Sf is the full load slip and
k=3/2pi*Ns

No load torque :- the torque
develop by the motor under
no load condition is known as
no load torque
