__History of Motor__ Andre Ampere and Hans Oersted made the most fascinating invetion.They discovered that electric current produces magnetic filled leading to the invention of the basic DC motor some ten years later. Nobody in particular is acclaimed.with the sole invention of the DC motor, as it was a gradual process with the involvment of many people.Michael Faraday from England set to prove theory proposed by Ampere and Oersted. In 1921, he succesfully demonstrated in his experiment by converting electrical energy into motion. His motor was made of a free-hanging wire that was plunged into a puddle of Mercury. A permanent magnet was placed in the centre of the Mercury pool. On passing through the wire, it rotated around the magnet.

10 years later, it was Joseph Henry who built an improved motor based upon Faradays experimental motor. He constructed whose rotating device part was an electromagnet with a horizontal axis. The motion resulted in two vertical permanent magnets, alternetly attracted and repelled at the end of the electromagnet. This made the magnet sway back and forth at 75 cycles per minute.

Uses of Motors __Cars,__ Lawn mowers, Fridge, Printer, Fan, Ships,Amusement park rides, planes, camera, robot, blow dryer, computer, freezer.

advantages and disadvantages of motors Some disadvantages of the AC motor is that unlike the DC motor, the speed control is unpredictable. the variables include many drives. Such as smooth turning or tarque. The device used in an AC motor, the AC drive is more complex than the DC drive. Some advantages are they can transmit high voltage, slip ring communicator used, voltage can be stepped up and down.
