Why rotor of an induction motor has slots around periphery filled with copper or aluminium?
The slots in the rotor of an induction motor are filled with copper or aluminum because those copper or aluminum filled slots are conductors. They constitute multiple one-turn Transformers, setting up an induced magnetic field, induced from the field windings, that creates a differential magnetic flux, i.e. a torque, that causes the rotor to turn.
This has little to do with the fact that the field windings are pulsing from the AC current, because the rotor "windings" are pulsing in turn - what is happening is that the rotor and field "windings" attract or repel each other as a function of their distance from each other, which is related to slippage induced by torque.

Is copper denser than aluminium?
Stainless steel is heavier then aluminium.
What is the percentage of aluminium in duralumin?
Duralumin typically consists of around 93-96% aluminum, with the remaining portion primarily composed of copper, manganese, and magnesium.
Does copper or aluminum rust faster?
Copper does not rust like iron; instead, it forms a green patina called verdigris when exposed to moisture. Aluminum also does not rust, but it can corrode when exposed to certain conditions, such as saltwater. Overall, aluminum tends to corrode more quickly than copper in most environments.
How can aluminum sulphate dissolve copper?
the aluminium is split with the sulphate ion. this leaves the sulphate on its own with a charge. the copper then takes the place of the aluminium turning the charge of the sulphate ion to neutral, this leaves the aluminium and copper sulphate.
What elements are in Cuznal?

Is copper or aluminium a good conductor of electricity?
copper
Does copper have aluminum?
Pure copper hasn't aluminium.
What is the effect of copper and aluminium since they metals?
copper and aluminium are metals since their metals the effect is that their good conductors
What is the body of aeroplane made of?
An aeroplane body is made up of an alloy (meaning: mixture of metals) of aluminium and copper. This is as aluminium is very light and cheap, but it needs copper as aluminium is too brittle. This way the plane have a weight of aluminium but the felexibility of copper!
What is the properties and is uses of copper aluminium iron and steel?
copper aluminium iron and steel is an excellent conductor of electricity and heat is one of the properties of copper aluminium iron and steel and it is used in conducting electricity.
Is copper denser than aluminium?
Stainless steel is heavier then aluminium.
Which metal is most reactive between copper and aluminium?
Aluminium is more reactive than copper. Aluminium can react with oxygen in the air to form a protective oxide layer, while copper does not readily react with oxygen.
What is an aluminium bronze?
An aluminium bronze is an alloy of copper containing 5 percent to 10 percent aluminium.
What is aluminum and copper's reaction?
Nothing, they simply form a mixture in molten state. A mixture of 10% Aluminium in copper is Aluminium bronze.
What alloy does aluminum iron and copper make?
There are some "aluminium bronze" alloys which contain aluminium copper with a small amount of iron and other metals- these are mainly copper with 4-8% aluminium and ess than 1% of other metals.
What is the weight of aluminum conductor as compared to a copper conductor?
Aluminium weighs less than copper for the given volume
Is copper more reactive then aluminium?
No, copper is less reactive than aluminum.
