What is better to brake a motor control braking or dynamic braking?
There are three type of electrical brakes that can be applied to motors. Regenerative Plugging in Dynamic "control braking" does not mean a correct description. Dynamic braking is better.
Cars with hybrid and electric motors?
It's called a hybrid because it's part gasoline engine, part electric motor. Thanks to the electric motor, the gasoline engine does not have to run all the time. And when a Ford hybrid is being powered by electricity, it's not burning gasoline. Good for fuel efficiency. Good for the planet. In most instances at low speeds and for short distances, Ford hybrids run exclusively on electricity. At higher speeds, and when you need more power, the gasoline engine kicks in. Ford hybrids also feature a Regenerative Braking System. Unlike a traditional gasoline engine where the energy generated by braking is lost, this innovative technology enables Ford hybrids to capture braking energy and store it for later use.
How are dragsters stopped?
Parachute-aided braking
Automatic induction braking system for vehicle?
I don't see why not. It would have to be electromagets providing the magnetic field, and they would draw electricity from a generator that is powered by the motor. For electric cars, however, the brakes would draw too much power and drain the battery.
Why use resistor grids in DC motors?
resistor grids were used in DC MOTORS during dynamic braking. in this method of braking a resistance ( variable) is connected across armature winding so as to dissipiate the energy. the energy thus dissipiated is used for braking of motors.
Why is the braking distance longer when the car is travelling at a higher speed?
Inertia.
What things can affect braking distance?
Things that affect braking distance consist of the following factors: * speed at which you're travelling * weight of the car * road conditions * braking efficiency * friction between the road surface and your tires Things that affect braking distance consist of the following factors: * speed at which you're travelling * weight of the car * road conditions * braking efficiency * friction between the road surface and your tires
What is electrical dynamic braking used for?
Braking is used to bring the motor to stop quickly or instantly. Braking can be two way broadly. One is mechanical braking. Other method is electrical braking. One of the electrical braking is dynamic braking.
What type of vehicle uses regenerative braking?
Hybrid or Electric
What is an example of a car traveling eastward and it acceleration be westward?
If it is braking while travelling eastward it is accelerating westward
What is electric braking of DC motors?
In a dc motor, when the supply is suddenly turned off, there is a suddenly fall of speed in motor. this is reduced by means of electric effect. Hence it is called electric braking ( By @FarajAlyami electric motor braking has two types 1- electromechanical 2- electrical but electrical has some types as : 1- regenerative 2- dynamice 3- plugging ( counter - current )
For what purpose would an electric brake controller be used?
When one is using a trailer on their car, an electric brake controller measures the car's braking speed and adjusts the electric braking power of the trailer to correspond. This helps avoid collision between trailer and car.
What distance is the distance traveled by your vehicle during the time it takes you to identify the need to stop and react to the braking situation?
depends how fast you are travelling
What affects breaking distance?
Several factors can affect braking distance in a motor vehicle.Speed, the faster you are travelling means a longer braking distance.Drivers reaction time, the road surface, efficiency of the brakes, efficiency of the tyres, and any combination of these factors.
What is the thinking distance the braking distance and the overall stopping distance for a veichle travelling at 20mph?
10 meters for thinking distance and 17 meters for stopping
Does air driven cars have heat?
The car can be powered solely by air, or combined (as in a hybrid electric vehicle) with gasoline/diesel/ethanol or electric plant and regenerative braking.
What is reactive braking?
This applies to electric or gas/diesel-electric vehicles. An electric motor can be instantly converted to an electric generator when polarities are switched. So, when you want your electric car to slow down or stop, you could have the motor suddenly turn into a generator. If the generator has very high electromagnetic flux, then it will act as a brake, and the kinetic energy of the vehicle is converted into electric charge in the battery.Hence, reactive braking actually "saves" the kinetic energy for future use. Gravity Reactive Braking involves using a special ratchet for wheelchairs and stationary machinery, in which the kinetic energy is rapidly converted into potential energy; the basic principle is similar to a steep ramp, used to slow down a rolling cart.Sometimes "reactive" braking means the brake system is mechanically designed to engage under certain conditions, such as excessive RPM.
