# Electrical – Should startup torque be higher in value than full load torque in an induction motor

electricalengineeringinduction motor

I found out values of my 3 phase delta connected induction motor for full load torque, maximum torque and startup torque.

My maximum torque was higher than my full load torque, but the thing I'm wondering about is whether I'm right or not is that my startup torque is higher than my full load torque. Is that right, or is it supposed to be lower than full load? If it's supposed to be lower than it shows I need to look over my calculations again.

Max torque= 322.4Nm

Startup torque= 38.53Nm

$$T = \frac {9.55 P_m} {n}$$
Where T = Torque, $$\P_m\$$ = mechanical power out and n = speed in rpm.
