2024 3-Phase Induction Motor

3 coil windings and 3 phase AC input are given to it.
This description is referred to..

• Stator

• Rotor

• Brush

• Ring

When a 3-phase current passes through the stator winding, it produces (a)   , which causes the rotor to turn.

The rotational speed of magnetic field is known as

• Motor speed

• Rotor speed

• Synchronous speed

• Shaft speed

When a closed conductor is placed in a magnetic field, according to Faraday's Law; as magetic field is varying, an ____ will produced in the loop which then produced a current in the same loop.

• Torque

• EMF

• rotational speed

• force

The difference between synchronous speed and rotor speed is known as

• slip
• slip speed

• shaft rotation speed

• rated speed

Which statement are NOT TRUE about Induction Motor

• No permanent magnet

• No brushes

• No commutator ring

• Not a self started

In order to make induction motor become an induction generator, the rotor speed must be ___ that RMF speed

• lower

• higher

• equal

Name a part of induction motor construction that helps the insulation of the internal electrical coil from melting.

• bearing

• fan

• motor frame

When electricity (current) passes through a wire, (a)   is generated around wire.

If we place a wire (with a current flowing through it) in a magnetic field, the wire's magnetic field will interact with the magnetic field of the permanent magnet, causing the wire to experience a...
