Current against slip relationship of induction machine?

Click For Summary
SUMMARY

The current against slip relationship in induction machines indicates that as the slip increases, the current drawn from the supply line also increases. This relationship is crucial for understanding motor performance, particularly under varying load conditions. When the load exceeds the motor's capacity, the slip increases significantly, leading to a higher current draw that can trigger overload protection mechanisms. Proper interpretation of this relationship is essential for effective motor management and troubleshooting.

Current against slip relationship of induction machine??

Please could someone explain to me the relationship between the current and the slip value of an induction machine. I have plotted a graph and I am wondering how to interpret this?

Thankyou.

If you are writing about an induction motor then the slip is the difference between the stator and rotor magnetic field. The larger the slip the greater the current pull from the line. When the motor is working there is always slip and if the load is too great for the motor the slip causes a higher than designed current pull and this trips an overload.
