What is the slip of a synchronous motor?
Synchronous motors have no slip. This is because the rotor runs at the same speed as the speed of the rotating magnetic flux of the stator.
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 are magnetic snaps used for?
Magnetic snaps are uses to keep your purse or bag shut. If your purse is open and has nothing to close it with your items are mosly likely to fall or slip out.
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%.
Why current will reduces after motor runs in constant?
Because the slip angle between magnetic fields decreases as the rotor comes up to speed.

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.
What is a circulation slip?
A circulation slip is a slip that circulates
What will happen if we slip rings are used in motors intead of commutator?
If slip rings are used, a dc field current fed to the rotor through the slip rings causes a magnetic field that rotates with the rotor. This is used in synchronous motors and also in alternators in cars and power plants. In a car alternator the dc current supplied to the rotor is used to control the votage generated in the stator, which is connected through diodes directly to the battery.
What a slide and cover slip used for?
A cover slip is used for covering a slip on a microscope A cover slip is used for covering a slip on a microscope
How single phase supply motor stator produce rotating magnetic field?
A single-phase motor has a pulsating magnetic field. That can be considered as two rotating fields travelling opposite ways round to form a standing field. In normal operation the rotor goes at slightly less than the synchronous speed in one direction, and the difference is called the slip. In that condition the rotor has a small slip relative to one of the rotating fields, but a very large slip relative to the other one. The field with the small slip generates very much more torque and the motor continues that way. However, unless the motor has a special starting winding, it will rotate one way or the other equally well depending on how it is spun when first switched on.
What is a borrowers slip?
