Hello everybody !
I have one problem with my simulation. I have an 18,5 kw induction motor in motoring mode , and i need to compare torque with rotor speed for differdent loads.
First , torque is rated torque which is 153,7 [Nm] and rotor speed reached 1200 rmp.
In second example torque is half of rated torque which is 76,8 but on the graphics torque is very high and rotor speed is good. Can someone explain me please?

Good day.
It seems ok for me. When no load on motor shaft Rotor Speed = Electrical Speed/P so no Slip
When u apply some torque rotor speed drops proportional Slip.
