Another induction motor question

[Spark40]

which factors might affect the slip and what losses may be incurred by the motor ?

Cannot find much about this, i know that the load indirectly affects slip due to the rotor speed changing, more load is more slip

Any assistance is appreciated, thank you

If any websites is found in referance to this question that will be great, thank you

Anyone?

The slip is the confusing part 0f the induction motor I understand what it is however im unsure what factors affect it except from load.

Last time ill post on here again.... looks like ill have no answers.......

Synchronous speed is the rotating magnetic field and rated speed is the speed of the shaft. The rated speed will always lag the synchronous speed as it tries to keep up due to resistance against the shaft from its own weight and also the load placed on it. The difference is known as slip.

I answered that question 3 minutes ago in good faith and still no thank you. I am disgusted by this forum sometimes!!

Give people chance to reply at least.

What information have you found and what ideas do you have?

We don't just do peoples homework for them.

Do a Google search for" Liii instrumentation". A document by Dr Tony .... Something will come up. Download it and then read up on the motor section. It is written in Johnny age 5 language which judging by your previous outburst is ideal for you.

Based on this post I don't think you'll be missed.

A hint: in order for currents to be induced in the rotor there must be relative motion - slip - between the rotating stator field and the windings of the rotor. There is then an electromagnetic interaction between the stator currents/field and the rotor currents/field which from Fleming's left hand rule produces a force/torque acting on the rotor windings (and an equal force of reaction on the stator coils). Then apply Newton's Laws of motion.

Didn't Fleming have another rule? .... something about patience,manners and assistance,all being in equilibrium?

@ spark40.youpost during working hours when most members are out earning the necessary and get peeved when nobody replies within 3 hours. PRATT !

sorry everyone, thanks for helpful comments

was just stressed from all the hard work and came back to see everybody is telling me off.

what the hell dudes

you are always rude to me and i have not done anything bar ask a realistic question

thank you for this, I was just confused abou the factors, i've grasped an understanding on what slip is, i have found the answers after doing intense research was only wondering if like minded people like yourselves could help a fellow brother out.

I've noticed the main factors is:
Load
Rotor resistance
Efficency

anymore will be appreciated

thx
