Here is the video covering all these details in motion. House hold generator or alternator is a machine which runs using fuel like gasoline or methane gas and producing line electricity to run electrical appliances like lights, motors and other house hold equipment. The generators are great machines to produce emergency electricity. They work very nicely if they are in their service life. They produce very clean and nice quality electricity suiting to most house hold needs. These machines are very reliable as long as they are good maintained.  An alternator consists of engine and generator or dynamo part. The engine is known as prime mover and running the generator to produce electricity. The dynamo or generator part is electrical part and is producing electricity which is further used. The alternator or generator has same like synchronous motor construction. It has two major parts like stater or armature and rotor or field. These two parts have winding on...

Here is my video focusing on points to be considered  to purchase a new car. Used cars are very common to purchase and sell. A used car is a good choice for a person on budget or for an average use where you can't put a new car. A used car is cheaper and affordable compared to a new one. Also a used car depreciation is not high compared to a new car. Sometimes in some areas the depreciation or de-rating of a used car is zero. Means the car is not devaluing its price if purchased and sold. The depreciation for a new car is very high. A used car can be purchase as long as it didn't complete its service life. The average service life for a car when is manufactured is expected twenty years. So if a used car had been purchased within its life time, it can still serve. Off course the price for used car is low enough compared to a new one. The used car for sure will need some maintenance after purchase. So if the maintenance cost for a purchased car is ...

Here is Youtube video covering all these details in motion. AC generator or alternator is a machine used to convert mechanical energy into electrical energy. The house hold alternator or generator is a combination of an engine and dynamo which produces line electric power which is 110 V or 220 V for house hold requirements. The power of the produced energy depends upon the size and capacity of the generator. A very common size now a days is 3KVA machine with gas engine from China manufacturing. Whereas there are other varients like 5KVA and 7KVA are also in use which has car engine and a local dynamo or alternator. There are diesel engine generator sets available. They are big machines normally with much more power capacity. The gasoline engines are sometimes run by regular gasoline and most of the time they are operated using line gas or Methane (CH4) if available locally. The methane or gas is cheaper for operating such engines compared to regular gasoli...

Here is a youtube video covering all these details. Must watch for understanding. Electric Motors are the running horses of any industry today. The are used anywhere from a house hold to a heavy industry. Everything from electric shaver to a car and an aeroplane contains electric motor. The definition of electric motor can be a device converting electrical energy to mechanical energy. A motor is taking electrical power and gives us a rotational torque which is further used to do a useful work. The motor is using electrical energy to do some useful work. A motor is used in a vehicle to start the engine from stand still to start condition. A motor is used to convey material in an industry. A motor is used to rotate a huge mill along with material. In other words electric motor is so important that it is used everywhere in day to day life. Motor are pron to wear and tear with time. Motor are overhauled after certain interval. Motor needs alignment when are remove ...

Here is the link to the cleaning process of throttle body and you can watch this procedure in video. The drive by wire is the newer technology used in cars since 2007 or so. In Toyota it had been introduced in Toyota Yaris model year 2007. In the drive by wire technology the throttle body throttle plate is actuated by an electric motor instead of a mechanical wire and cable arrangement actuated by foot. In the drive by wire system the driver of a vehicle is footing on gas pedal which actuates a set of sensors. They can be some times magnetic sensors and sometimes variable resistors or potentiometers. So by footing on gas pedal a voltage signal is produced proportional to the pressure on the pedal. This voltage signal is feed then to the ECU or PCM of the vehicle. The ECU or PCM is using this signal as input. There are other inputs to the PCM also like MAF sensor, O2 or Oxygen sensor etc. Then ECU or PCM is deciding how much to open the throttle plate to ensure the corr...
