3.  Purpose of life:
khalifa
 And I did not create the Jinn and mankind except to worship Me… (Quran)

4.  To achieve real happiness of life by worshshping the allah
 To help poor and needy people
 education

5.  Aim in life
 Engineer
Cricket
football

6.  electric motor
 An electric motor is an electrical machine that
converts electrical energy into mechanical energy.

7.  History
 Andrew Gordon in 1740s…..first time
 Electromagnetic Michael Faraday 1820s.
 First invent dc motor 1834.

8.  Classification

9. AC Motors

10.  Main Patrs of ac motor
 Rotor: moving part….
 Stator: stationary part…
 Air gap: distance b/w rotor and stator.
 Diffcult to control speed.

11. Manfacturning of ac motor
 Rotor and stator are main parts …..
 On stator copper wire is installed
 The wire are seprated from each other by insulated core of fiber glass
 Each coil consist of 30 turns of copper wire
 Tie the coil
 Makes connections of wires
 Bind the wire with stator so that its not move
 Add stator in oven at 280

13.  Dc motor
 A DC motor is any of a class of electrical machines that converts direct
current electrical power into mechanical power.

14.  dc motor main parts
 Axle
 rotor
 stator
 Commutator
 field magnet
 brushes

15.  Working of dc motor

16.  Comparison
 Dc motor
 Direct current(dc)
 DC motor has- Armature that rotates, & Field
winding that stays stand still
 Simple
 Cheap
 Speed control
 Short life
 Ac motor
 Alternating current(ac)
 Ac (Induction) motor has- Stator that stays stand
still and provides rotating field, rotor that rotates
 Complex
 Expensive
 Not easy to control speed
 Long life

17. Electric motor industry in pakistan
 Arrow's Technology Corporation
 Jan's International Trading House Pte
Ltd.
 Prime Switchgear Industry (Pvt.) Ltd

18.  Application in daily life
 Electric fan
 Water pump
 Bike
 motor Car
 Washing machine
 Circuit bracker
 Computer hardware
 Moblies

19.  Thanks for watching
Best of luck class
