@M.ÇağlarTUFAN It is best to ask such questions on the EE site rather than in chat. There aren't many people in chat most of the time.

Hello, I had a quick question about regenerative brake for AC motor, but I didn't know if this topic was the right one for it ? (in short it's to know if you can strongly brake at 50kmp with a electrical motor for cars, or if it will be less strong than 130kmp, and if you can control the strength of the brake ?)

@julien2313 Are you designing a power train for an electric car?

Not at all, it was just a discussion I had with my father, and I didn't find any source :/

@julien2313 yes, the regenerative braking on a car can be modulated/controlled (generally, there's a setting for how much regen you get at zero-throttle, and the rest is handled through blended braking algorithms: when you step on the brake pedal in an EV, the car decides how much of that brake demand is being serviced by the foundation brakes and how much is handled by regen)

(very old EVs used DC traction motors because AC traction requires good power semiconductors to work -- and those struggle a fair bit with regen/dynamic braking falling off at low speed)

@julien2313 might be worth asking over in The Pitstop though

what and where is this "The Pitstop" ? ^^

@julien2313 they regen well at low speeds -- I don't have any indepth reading on the topic unfortunately though

thank you for the link !

I'll ask my question their :)
