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