how motor works?

Answer 1

electrical or gasoline? I'll explain both.

Electrical: once in science class, I learned how these work. as an armature with electromagnets spins, the brush on the end picks up different flows of electricity to always repel the permanant magnets on the insides of the motor case. Some armatures may even have 3 to 4 electro-magnets.

Gasoline: I actually took a kind of class on gasoline engines. a valve takes in gasoline and then closes to let the gasoline compress by the piston, which starts moving by a starter or with small Briggs and Stratton type engines or lawn mowers, a rip cord. then the spark plug fires a chrarge, in some motors from a magnet and coil on the flywheel, others from the battery. that forces the piston downwards, and then it has enough momentum to continue up so another valve opens and the exhaust is propelled out through the valve by the piston.

Thats the basic simplified version. Here, check out these howstuffworks.com links they should give a better explanation.

current or AC motors. The reference of DC or AC refers to how the electrical current is transferred through and from the motor. Both types of motors have different functions and uses. Dc motors come in two general types. They can have brushes or be brushless. AC motors, as well, come in two different types. They can be two phase or three phase. The differences in DC and AC motors are sometimes subtle, but these differences are what make one types better for a certain use.

Direct current or DC electric motors work for situations where speed needs to be controlled. DC motors have a stable and continuous current. DC motors were the first and earliest motors used. They were found, however, to not be as good at producing power over long lengths. Electric companies found using DC motors to generate electric did not work because the power was lost as the electric was transmitted. Brush DC motors use rings that conduct the current and form the magnetic drive that powers the rotor. Brushless DC motors use a switch to produce the magnetic drive that powers the rotor. Direct current motors are often found in appliances around the home.

Alternating current or AC electric motors are used differently based on what type of AC motor it is. Single phase AC motors are known as general purpose motors. They work well in many different situations. These AC motors work great for systems that are hard to start because they need a lot of power up front. Three phase, also called polyphase, AC motors are usually found in industrial settings. These motors also have high starting power built transmit lower levels of overall power. AC power gets its name from the fact that it alternates in power. The amount of power given off by an AC motor is determined by the amount of power needed to operate the system.

DC and AC electric motors are found everywhere from the home to the car to industrial plants. Motors are important to everyday life. Dc motors were introduced and caused a great revolution in the way many things are done. When AC motors came on the market the way motors were looked at changed because of their amazing starting power potential. DC motors and AC motors are different in many ways, but they still both are usede to power the world.

Answer 3

For a gas engine, on the down stroke of the piston, the inlet valve is opened by the cam shaft, air is drawn in with gas added either by the carburetor or fuel injector. Inlet valve closes, piston begins compression stroke. Near end of compression stroke, spark plug fires and ignites the mixture. Piston is forced down in power stroke. The cycle is completed with the exhaust stroke where exhaust gases are pushed out of the cylinder through the exhaust valve. For more detailed information see howstuffworks.com
