if a 3 phase induction motor of 5 hp has speed of 1430 at rated load then what is its speed at 50% load?

please expalin.

thanks.

 

Look up induction motor slip.

 

thanks but that didnt help.

 

What is the synchronous speed of the motor?

That is never going to be the same for each motor, individual characteristics of the motor, stator/rotor etc, come into play.
The example motor in the question would be a 50hz motor.
Max.

 

Figure out the synchronous speed of the motor. Assume the line is 50 hz.

It is an induction motor. Induction motors produce ZERO torque at synchronous speed.

Yours produces 100% of rated torque at 1430 rpm.

Slip is a ratio of two numbers.

A ratio is the division of one number by another such that the mathematical answer is equal to or between 1 and zero.

If you can't get there from here then you are wasting time trying to learn this particular subject.
