rapid torque fluctuations caused by the turbulence of the wind. 7.2 Variable-speed induction generator The induction generator described above can be adapted to operate at variable speed by the application of power-electronic frequency converters. Similar converters are widely used in general industry to provide variable speed drives (usually motors). In wind turbines‚ variable-speed operation has the big advantage that the inertia of the rotating parts serves to smooth out the torque fluctuations

Solar Vehicle EGR 100 12/3/2013 Introduction Living on Michigan State’s campus‚ one is constantly reminded to “Be Spartan Green”‚ whether it is turning off the lights or taking a shorter shower‚ Spartans are always striving to be the most ecofriendly students that any university could have. The problem at hand is to create a vehicle using only green technology‚ such as solar panels‚ and have this car race up a ramp as fast as possible‚ with a shorter time being ideal. There are many requirements for this project

Fuel economy is 14/20 mpg city/highway for 4x2 models and 13/20 mpg city/highway for 4x4s. Maximum towing capacity is a robust 7‚400 pounds. The Grand Cherokee SRT8 is powered by a 6.4-liter V8 engine with 470 horsepower and 465 pound-feet of torque. This 4x4 model is paired with a five-speed automatic and has a 0-60 mph time of about five seconds. This model makes an EPA-estimated 12/18 mpg city/highway. The 2013 Grand Cherokee offers three four-wheel drive systems. Quadra-Trac I is exclusive

It’s on par for power with the Clio Turbo (197bhp) and comfortably ahead of the little fast Ford (180bhp) and its 203lb ft of torque puts it between the two (214lb ft for the ST‚ and 177lb ft for the Clio). The 0-62mph sprint is dispatched in 6.8 seconds‚ one-tenth slower than the Clio but one-tenth faster than the Ford. It’s as clean and efficient as the Ford‚ and thus cleaner

system. Electrodynamic meters have a fixed coil‚ inside of which is a movable coil and a pointer on a spindle. A torque is developed around the spindle by the interaction of the currents in the two coils and is proportional to the product of the effective values of the currents. A counter torque is created by a spring connected to the spindle. The pointer comes to rest when the two torques are equal. Thermocouple ammeter Thermocouple ammeter or RF meter

speed‚ since internal combustion engines in automobiles operate between 600 and 7000 revolutions per minute (rpm) whereas wheels rotate between 0 and 1800 rpm [1]. Moreover‚ transmission ensures the proper amount of torque according to the speed of the car. For example‚ greatest torque is required to move the car from rest; however‚ one needs greater rpm for high speeds. A transmission may have multiple gear ratios that require switching as the speed varies. Switching can be done manually (by the

Electric cars are automobiles they use one or more electric motors‚ other than using more common gasoline powered engines. Electric cars use batteries; batteries are used to store energy. Since Electric motors don’t have to warm up they have instant torque‚ creating strong and smooth acceleration‚ which can give you a more satisfying ride. Electric cars are safer and better than gasoline powered cars‚ since they aren’t polluting the air as much as gas powered cars. Electric cars are high demand cars
