4) What is the formula to calculate the slip speed (Nslip
of 3 phase squirrel cage induction motor?
Answers
Answer:
The multiplication of 100 and speed difference divided by the synchronous speed is known as slip of an induction motor. It's always represented in percentage, generally it ranges from 0.4% to 6% based on its design factors.
hope it helps I tried my best
be happy dear a lot of blessings
Answer:
The difference between the synchronous speed and the rotor speed is called as the slip speed
Slip speed = Ns - Nr
Slip is defined as the ratio slip speed to the rotor speed .
Explanation:
3 phase squirrel cage induction motor:
A 3 stage squirrel confine enlistment engine is a sort of three stage acceptance engine what capabilities in view of the rule of electromagnetism. It is known as a 'squirrel confine' engine on the grounds that the rotor within it - known as a 'squirrel confine rotor' - seems to be a squirrel confine.
This rotor is a chamber of steel overlays, with exceptionally conductive metal (normally aluminum or copper) implanted into its surface. While a substituting current is gone through the stator windings, a turning attractive field is created.
This prompts an ongoing in the rotor winding, which creates its own attractive field. The collaboration of the attractive fields delivered by the stator and rotor windings creates a force on the squirrel confine rotor.
One major benefit of a squirrel confine engine is the way effectively you can change its speed-force qualities. This should be possible by basically changing the state of the bars in the rotor. Squirrel confine enlistment engines are involved a great deal in industry - as they are solid, self-beginning, and simple to change.
