### Brake selection problem

I have a quick question guys. I am gonna select a brake but I am not sure. A Crane Hoist motor has a rating of 300 HP and maximum speed of 1800 rpm. This motor is attached to a gearbox with a perfect (...

### Can a car's Electronic Stability Control (ESC) operate using electromagnetic braking?

The Wikipedia article for ESC describes the process as using hydraulic anti-lock brakes. However, is it possible for electromagnetic braking to be used instead, with an electic motor/generator in ...

### Calculating the Braking Energy of a vehicle

you might find my question stupid. I am unfortunately not an engineer and didn't find the answer on google. I want to calculate the braking energy of a vehicle decelerating from v2 to v1 (km/h). ...

### Why can't energy be entirely recovered from a moving car's rotating wheels?

I have a friend who isn't properly visualizing energy loss in a moving car. His idea: Cars that can run forever without being recharged - - > while the engine rotates the front wheels the move the ...

### Why don't most consumer vehicles use kinetic energy recovery systems?

I know that Formula One and some sports cars have KERS systems to recover kinetic energy, but is there an expense/practicality barrier to installing them in consumer vehicles? As the technology ...

### Does an electric vehicle going downhill recover energy?

I have to model the behavior of an electric car. For this, I use these equations and I can observe by "playing" with parameters that, when going downhill at constant speed, the car has a negative ...

### Regenerative Braking of DC motor

I'm looking to implement a simple regenerative braking circuit in order to measure how much energy could be regenerated using a DC motor. My knowledge of electronics is very basic to say the least so ...
If I have an electric vehicle on an incline (m=17,300 kg) I want to figure out how much energy it would generate by regenerative braking. I've used $a= g \cdot \sin({\theta})$ and $f=m\cdot a$. <...
