The starting torque of a motor is that torque which is produce by it at start. It is denoted by T

The maximum torque is denoted by T

**induction motor torque formula**is as follows:The starting torque of a motor is that torque which is produce by it at start. It is denoted by T

_{st}and corresponds to s = 1. So by substituting s = 1 in above expression, we get the expression for starting torque. Therefore*starting torque formula for induction motor*is as follows:The maximum torque is denoted by T

_{m}and occurs at s = R_{2}/X_{2}. The value of slip which corresponds to maximum torque is denoted by s_{m}. So by substituting s = R_{2}/X_{2}in full load torque expression, we get the maximum torque expression. Therefore maximum torque formula for induction motor is as follows:
