Difference between motor and engine

Posted By: Sm Adminon: November 04, 2015In: Miscellaneous

Motor:
A motor is a device that creates motion. In simple terms, a motor is a device which converts mechanical energy into electrical energy. Motor is generally used to refer to a rotating device such as an electric motor. Motor needs electricity to work or operate.
Engine:
An engine is a machine which converts energy into useful mechanical motion. Engine is a mechanical device which converts force or heat energy into motion. Fuel is required for an engine to work. The word engine refers to a reciprocating engine (stem or internal combustion).
Differences:

Basis	Motor	Engine
Definition (www.oxforddictionaries.com)	A machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for another device with moving parts	A machine with moving parts that converts power into motion
Synonyms	Turbine, transformer, generator, cylinder and mechanism	Weapon, appliance, instrument, diesel and tool
Antonyms	Noncausal, afferent, noncausative
Types	Its types are: DC motor AC motor Synchronous motor Induction motor One phase induction motor Three phase induction motor Special motor	Its types are: Heat engine Combustion engine Internal combustion engine External combustion engine Air-breathing combustion engines
History	In the year 1886, the first electrical motor was invented by scientist Frank Julian Sprague. That was capable of rotating at a constant speed under a varied range of load, and thus derived motoring action.	Simple machines, such as the club and oar (examples of the lever), are prehistoric. More complex engines using human power, animal power, water power, wind power and even steam power date back to antiquity. Human power was focused by the use of simple engines, such as the capstan, windlass or treadmill, and with ropes, pulleys, and block and tackle arrangements; this power was transmitted usually with the forces multiplied and the speed reduced.
Word origin	It was originated from the Late Middle English (denoting a person who imparts motion): from Latin, literally ‘mover’, based on movere ‘to move’.	It was originated from the Middle English (formerly also as ingine): from Old French engin, from Latin ingenium ‘talent, device’, from in- ‘in’ + gignere ‘beget’; compare with ingenious.
Works with	Motor works with electricity.	Engine works with fuels.
Pronunciation	Eng (UK): /ˈməʊtə/ Eng (US): /ˈmōdər/	Eng (UK): /ˈɛndʒɪn/ Eng (US): /ˈenjən/
Main function	The main function of the motor is to convert electricity into motion.	The function of engine are: The spark plug in the engines supplies the spark that is required to ignite the air and fuel mixture. Valves allow for fuel and air to enter the combustion chamber and later let the exhaust out. Piston and Piston rings provide a sealing edge between the exterior of the piston and the interior of the cylinder. As the piston moves up and down due to the controlled explosions, it causes the connecting rod to move. This then cause the crankshaft to move as well as it is connected to the connecting rod, in a circular motion due to the configuration of the piston, connecting rod and crankshaft. Surrounding the crankshaft, the sump contains some amount of oil.
Made up of	Motor is made up of rotors and stators.	An engine is made up of pistons and cylinders.
Energy uses	Motor provides energy using various forms.	Engine uses energy in required form.
Converts	Motor converts the mechanical energy in hydraulic energy.	Engine uses energy in required form.
Advantages/Benefits	Its advantages are: Low initial cost Long life Low maintenance requirements High efficiency Automated control No fossils fuels Labor cost savings Occupational safety	Its advantages are: Low maintenance cost Peppy drive Don’t produce excessive noise Petrol engine is environment friendly
Disadvantages	Its disadvantages are: Portability Demand charges Remote locations Speed control	Its disadvantages are: Consumes more fuel Overall cost is high Grunty and crude Diesel engines cause pollutions
Example in Sentence	An electrical motor does not cause noise. Ramesh could not start the motor.	The engine is not working properly. He repaired the engine so it works well.
