- The Relation Between Torque and Slip-In An Induction Motor
The importance of slip in the induction motor can be discussed below based on the values of a slip because the motor behavior depends mainly on the slip’s value.
The formula of the slip in the induction motoris given below. Slip = (Ns-Nr/Ns)*100 In the above equation, ‘Ns’ is the synchronous speed in rpm whereas the ‘Nr’ is the rotational speed in the rpm (revolution for each second)
If the synchronous speed of the motor is 1250 and the actual speed is 1300 then please find the slip in the motor? Nr = 1250 rpm Ns = 1300 rpm The speed difference can be calculated as Nr-Ns = 1300-1250 = 50 The formula to find a slip in the motor is (Nr-Ns)*100/Ns = 50*100/1300 = 3.84% While designing the induction motor, measuring the slip is ess...
The relation between torque and slip in an induction motor provides a curve with the information regarding the difference of torque using the slip. The deviation of slip is attained with the difference of speed changes & the torqueequivalent to that speed will also differ. The curve is defined in three modes like motoring, generating braking and th...
What is Slip of the Induction motor: Slip is nothing but the ratio of the difference between the synchronous speed (Flux speed) to actual motor speed to synchronous speed. It is normally expressed in S. [wp_ad_camp_1] S = Ns-N/Ns. Where S is Slip. Ns= Synchronous speed. N= actual motor speed.
Jun 27, 2021 · In this topic, you study Slip in Induction Motor. In an induction motor, it is impossible for the rotor to run at synchronous speed. If it runs at synchronous speed, there will be no relative motion between the rotating magnetic field produced by the stator and the rotor conductors.
Definition: The slip in an induction motor is the difference between the main flux speed and their rotor speed. The symbol S represents the slip. It is expressed by the percentage of synchronous speed. Mathematically, it is written as, The value of slip at full load varies from 6% in the case of a small motor and 2% in a large motor.
Aug 8, 2023 · What is the concept of slip in an AC induction motor and its significance? Answer : In an AC induction motor, slip refers to the difference between the speed of the rotating magnetic field (synchronous speed) and the actual speed of the rotor. The synchronous speed is determined by ... .
