# What is the value of the slip for an induction motor at no load and full load?

Contents

At full load the speed of the motor is 1350 rpm. Hence slip at full load = 5.33% When the motor is so loaded that the rotor speed is reduced to 0, the value of Slip is 1. Hence, value of Slip gradually increases from no-load to full load. Hope this helps!

## What is the value of slip if the induction motor is run unloaded?

The slip value is equal to ‘1’ as the rotor in the motor is at rest & it will not equivalent to ‘0’. So while operating the motor, the synchronous speed is not equivalent to ‘N’ i.e, actual speed in a given time.

## What is the maximum value of slip in induction motor?

(3.68), this maximum slip frequency is a function of leakage inductance, and thus, its range depends on the total leakage inductance, X l s + X l r . For a standard induction motor, this value is normally 0.2 p.u., producing a constant power range up to two to three times the rated speed.

When an induction motor is loaded from no load to full load, its speed decreases & slip increases.

## What happens if fifth harmonics is given to induction motor?

What happens if fifth multiples of harmonics is given to induction motor? It will rotates in reverse direction.

## What is the value of slip at full load?

At full load the speed of the motor is 1350 rpm. Hence slip at full load = 5.33% When the motor is so loaded that the rotor speed is reduced to 0, the value of Slip is 1. Hence, value of Slip gradually increases from no-load to full load.

## What is slip in 3 phase induction?

This speed difference is called slip. Therefore, the difference between the synchronous speed Ns of the rotating stator field and the actual rotor speed N is called slip. The slip increase with load and is necessary for torque production. Slip speed is equal to the difference between rotor speed and synchronous speed.

## Can slip be negative?

If the rotor of an induction machine rotates above synchronous speed, slip is negative, as are torque, mechanical output power and air gap power. … If slip is negative, the “input power” to the electrical terminals will be negative, implying that power is flowing out of the electrical terminals.
