The rotor time constant T can also be determined using an ammeter instrument. In this case
leave the motor running under load and change the value of t until minimum motor current
throughput is obtained.
Extended anchoring adjustment range (delta connection with 87 Hz characteristic)):
Parameter T is determined using the above formula with the motor rating plate data for 50 Hz
operation (star connection). Although the overall rotor time constant is dependent on the size
of the motor, it does not change if the output and speed increase proportionally.
