Why rotor of an induction motor has slots around periphery filled with copper or aluminium?
Wiki User
∙ 12y ago
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.
Is romex pure copper?
Copper or aluminium.
Does copper or aluminum rust faster?
Neither rust. Only iron rusts. However, copper and aluminium both oxidise. Aluminium oxidises extremely quickly. It you cut a piece of aluminium in the air, it immediately oxidises. The surface that you see/feel for aluminium is actually aluminium oxide. (Al2O3). The surface of aluminium pots and pans in the kitchen is actually aluminium oxide. . Aluminium oxide is impervious to further oxidation and so the aluminium underneath remains as aluminium . Copper on the other hand is a much slower oxidiser. The brown/red colour of copper metal will slowly tarnish (oxidise) over a period of days and weeks, to become a dull colour and if left for a longer time , may go black as copper oxide, or green as copper carbonate.
What elements are in Cuznal?
Copper Zinc and Aluminium It's a word out of the symbols Cu (Copper) Zn (Zinc) & Aluminium (Al)
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.

Copper or aluminium.
Does copper have aluminum?
Pure copper hasn't aluminium.
Is copper or aluminium a good conductor of electricity?
copper
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.

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.
