I am trying to find some numerical solution for finding starting current and starting torque for three phase squirrel cage induction motor.
Some of the data I measured in energy meter such as
- no load test: VA=81.40 , W=20.11 , P.F.=0.255
- block rotor test: VA=899.7 , W=375.3 , P.F.=0.417
The motor rated voltage on the name plate is 150 V and rated frequency is 150 Hz. Power output is 275 W and 2 pole machine. I have some data which is starting torque 60% and starting current 570%.
Here I am confused on how to measure the starting torque and starting current value any way I need to calculate. If it is possible by circle diagram then please tell me how because I have limited data. Any equation so that I can get solution by using RS-485 communication type energy meter.
How can I get the solution?
