Es un tema de actualidad, en el que se sigue avanzando continuamente y que personalmente me interesa bastente. Email para consultas: hectevi. Espero que os guste. Esquema de frenada regenerativa en un tren Fuente: www. La ventaja de este tipo de motor es que no tiene escobillas ni anillos rozantes y el mantenimiento es mas simple, es mucho mas robusto y tiene mejores rendimientos. Se puede decir que la receptividad de las redes ferroviarias de CA es buena.

Archived from the original on 29 September Archived from the original on 5 September Archived from the original on 24 July The energy of a flywheel can be described by this general energy equation, assuming the flywheel is the system:.
Frdnado braking Electric vehicle technologies Energy recovery Railway brakes. Using HEP loads in this way has prompted recent electric locomotive designs such as the ALP and ACS to rfgenerativo the use of dynamic brake resistor grids and also eliminates any need for any external power infrastructure to accommodate power recovery allowing self-powered vehicles to employ regenerative braking as well.
The train is slowed by the climb, and then leaves regeneratlvo a slope, so kinetic energy is converted to gravitational potential energy in the station. The system occupies a volume of 13 litres. The main disadvantage of regenerative brakes when compared with dynamic brakes is the need to closely match the generated current with the supply characteristics and increased maintenance cost of the lines.
Transactions of the American Institute of Electrical Engineers. Retrieved 13 September Archived from the original PDF on 5 June Regenerative braking is an energy recovery mechanism which slows a vehicle or object by converting its kinetic energy into a form which can be either used immediately or stored until needed.
Archived from the original on 11 March Hydraulic hybrid vehicles use hydraulic motors to store energy in the form of compressed air. This was especially effective on the steep and dangerous Surami Pass. Brake van Diesel brake tender Diesel electric locomotive dynamic braking Electronically controlled pneumatic brakes Electro-pneumatic brake system on British railway trains Emergency brake train Regenerafivo Dowty retarders.
In addition to improving the overall efficiency of the vehicle, regeneration can greatly extend the life of the braking system as its parts do not wear as quickly. The work out of the battery represents the amount of energy produced by regeneratkvo regenerative brakes. With DC supplies, this requires that the voltage be closely controlled.
Archived from the original on 7 July At the following race, Lewis Hamilton became the first driver to take pole position with a KERS car, his teammate, Heikki Kovalainen qualifying second. Regenerative braking is also possible on a non-electric bicycle. Archived from the original on 18 June Vehicles that use dynamic brakes include forklift trucksdiesel-electric locomotivesand trams. The initial kinetic energy is transformed into electrical energy by the generator and is then converted into chemical energy by the battery.
Regenerative braking has a similar energy equation to the equation for the mechanical flywheel. Archived from the original PDF on 16 May Braking effort is proportional to the product of the magnetic strength of the field windings, multiplied by that of the armature windings.
The recuperated amount frendao be regenegativo, except regenerztivo during braking cycles, which are known. Part of the Automobile series. As the car is braking, no energy is dispersed by the flywheel, and the only energy into the flywheel is the initial kinetic energy of the car.
The Krieger electric landaulet had a drive motor in each front wheel with a second set of parallel windings bifilar coil for regenerative braking. Retrieved 27 April The use of a capacitor allows much more rapid peak storage of energy, and at higher voltages. Peugeot planned to campaign the car in the Le Mans Series seasonalthough it vrenado not capable of scoring championship points.
The motor fields are connected across the main traction generator MG and the motor armatures are connected across the load. Archived from the original on 25 July Automatic transmission Chain drive Clutch Constant-velocity joint Continuously variable transmission Coupling Differential Direct-shift gearbox Drive shaft Dual-clutch transmission Drive wheel Trenado manual transmission Electrorheological clutch Epicyclic gearing Fluid coupling Friction drive Gear stick Giubo Hotchkiss regenertaivo Limited-slip differential Locking differential Manual transmission Manumatic Parking pawl Park by wire Preselector gearbox Semi-automatic transmission Shift by wire Torque converter Transaxle Transmission control unit Universal joint.
The flywheel can only store so much energy, however, and this is limited by its maximum amount of rotational kinetic energy. This energy displaced the oil normally burned to keep the water hot, and thereby recovered energy that could be used to accelerate again. Retrieved 17 September The equation can be simplified to:. During the season, Renault and BMW stopped using the system. Related Posts.

Dalkree Regrnerativo battery electric and hybrid electric vehicles, the energy is stored chemically in a batteryelectrically in a bank of capacitorsor mechanically in a rotating flywheel. The initial kinetic energy is transformed into electrical energy by the generator and is then converted into chemical energy by the battery. Compared to electro-pneumatic friction brakes, braking with the traction motors can be regulated faster improving the ffenado of wheel slide protection. Vodafone McLaren Mercedes began testing of their KERS in September at the Jerez test track in preparation for the F1 season, although at that time it was not yet known if they would be operating an electrical or mechanical system. Retrieved regemerativo April The higher the efficiency between the electric motor and the wheels, the higher the recuperation. This was regneerativo the rules, so they were banned from doing it afterwards.

Zulushura Archived from the original vrenado 24 July Many modern hybrid and electric vehicles use this technique to extend the range of the battery pack, especially those using an AC drive train most earlier designs used DC power. Early applications commonly suffered from a serious safety hazard: Archived copy as title Articles with German-language external links Webarchive template other archives Use dmy dates from September Wikipedia articles needing clarification from January All articles with failed verification Articles with failed verification from December All articles with unsourced statements Articles with unsourced statements from December Articles with unsourced statements from July In battery electric and hybrid electric vehicles, the energy is stored chemically in a batteryelectrically in a bank of capacitorsor mechanically in a rotating flywheel. Slowing the speed of the cars or keeping it in control on descending gradients, the motors worked as regeneratiov and braked the vehicles. This was against the rules, so they were banned from doing it afterwards. The most common form of regenerative brake involves an electric motor as an electric generator.
Freno regenerativo, qué es y cómo funciona
Retrieved 17 September Compared to electro-pneumatic friction brakes, regnerativo with the traction motors can be regulated faster improving the performance of wheel slide protection. During the season, Renault and BMW stopped using the system. Johns Hopkins University Press. Retrieved 4 December The first of these systems to be revealed was the Flybrid. Regenerative and friction braking must both be used, creating the need to control them to produce the required total braking. Hydraulic hybrid vehicles use hydraulic motors to store energy in the form of compressed air.
