Induction Motor Torque
The mechanical power P available from any electric motor can be expressed as:
P= 2πNT / 60 watts
Induction Motor Torque
The
mechanical power P available from any electric motor can be expressed as:
P= 2πNT / 60 watts
Where
N =speed
of the motor in r.p.m.
T =
torque developed in N-m
If the
gross output of the rotor of an induction motor is Pm and its speed
is N r.p.m., then gross torque T developed is given by:
Note.
Since windage and friction loss is small, Tg = Tsh,. This
assumption hardly leads to any significant error.
