3) Electrical motor stater
Aim :- to know about the electrical motor starter .
Requirement :- plier , screwdriver, all type of spanners ,hammer ,tester, wire cutter , electrical
Procedure :- first we took a starter and we started to find the faults in the starter. And took the information about the starter then we took the information about the parts of the starter then we took the information about each part and it’s working process .
Relay :- it is use to set the overload connection current .it contain two strips of bio metals.
Biometals strip :- when current is more the circuit breaks .the one strip of lower temperature gets Bend due to heat.
Plangers :- it is use to bring the supply back to the current.
Non volt coil :– it gets a magnetic field . and energy is created
Trouble shoot :- in starter ,
In case if supply given to the started while testing on a lamp if the lamp glows then the coil not working .and if the supply given to the started and lamp glows dim then coil is working ok.
We can also check by the magnetic field created by the coil.it the coil does not produce
Magnet then it is faulty and if it produces magnetic field then it is working properly .
