Difference between induction motor and induction generator?
in case of induction motor the rotor speed is less than synchronous speed giving positive slip but in case of generator the rptor speed is greater than synchronous speed giving negative slip.......
What in slip speed control?
slip speed control refers to induction machines s=(synchronous speed-motor speed)/synchronous speed by varying slip the machine can be either be operate in generated mode or motor mode
What is meant by Slip of an induction motor?
Slip is referred to as the difference between the speed of the rotor and the speed of the rotating magnetic field in the stator of the induction motor. Speed of the rotor=n(1-s) Speed of the rotating magnetic field= f/p
What is a slip in electricity?
it is the difference between the synchronous and asynchronous speed of a induction motor
Slip power in a induction motor?
slip power is a power which is develop by the induced voltage and current in an induction motor

Can a Squirrel Cage Induction motor can be converted to Slip Ring Induction Motor?
yes
Why 3 phase induction motor never atteined sinkronas speed?
Induction motors run at sub synchronous speeds because the slip (difference between synchronous and actual speed) causes, or controls the electric field strength in the motor. As more load is put on the motor, the motor's speed decreases, increasing slip, and increasing the electric field strength.
How do you find the slip in induction motor?
calculate the synchronous speed from the frequency & the no. of magnetic poles in the stator, then measure the actual speed of it with a tachometer, then subtract the actual speed from the synchronous speed.
How is slip in three phase induction motor different from slip in single phase induction motor?
They are the same thing: (Nsync - N)/Nsync, or 1 - N/Nsync
What is difference between frequency and slip frequency?
Both 3-phase induction motors and single-phase induction motors have rotating magnetic fields assuming that the single-phase motor has one of the usual starting mechanisms built-in. The synchronous speed is given by RPM = 120 X f / p where f is the frequency and p is the number of poles. The conductors in the rotor pass through the magnetic field of the stator at the slip speed. As a result an alternating current is generated in the rotor. The frequency of that current is the rotor frequency or slip frequency given by slip frequency = slip speed X p / 120. At full load, the slip speed of a standard, 3-phase motor is about 1% to 2.5% of synchronous speed. A motor with 6% slip would be classified as a high-slip motor. The slip of a standard single-phase motor could be 6%.
What is the relationship between torque and slip?
Torque in an induction motor is proportional to slip, which is the difference between the synchronous speed and the actual rotor speed. As slip increases, torque also increases, up to a certain point. This relationship is key to understanding the motor's operating characteristics.
