How to brake using electric motor?

[Jessiedog1234567]

Hello,
Can someone please let me know how or if it is possible to brake a small child's ride on car using the motor( dynamic braking?) rather that mechanical braking.
I would be using a 36v 500w brush motor, a speed/motor controller and a foot accelerator pedal.
I want to if I can avoid it using disc brakes etc.
Are there controllers that have this facility incorporated into them or how can it be done?
Any advice welcome. Thanks

Most controllers have that capability. Called regenerative braking or regen. It may not work til 0 speed though. I assume the car will be going really slow so there are no safety issues with not having a backup brake.

The regen braking done by Ebike, scooter, and other controllers of this type isn't a replacement for a primary brake. It doesn't stop the wheel, it just slows it down. And the slower your rolling, the less it works

It works more like a drag chute on a dragster than a real brake.

They also cut out at full charge. So if you unplug from the charger and aim the car down the driveway, weeeeeeeeeeeeee No Brakes!

My ASI controllers do in fact stop the wheel. It sounds like he wants a cheap one which won't. Regardless I don't think there's a big safety issue if it only goes a few mph.

You need a specific controller for the brushed motor which has regen. The regen resistance may be variable. A high level can stop a vehicle on a medium slope say 7%. Its a complement for standard brakes.

Hi there.
Am I right guessing you're building this kiddie car? Lucky kid. Are you set on running 36v? If 24v would be ok, you might think about finding an old mobility scooter. Non workers go for next to nothing. Often it's just read batteries. You get a brushed motor, a programmable controller with auto dynamic braking as in when you ease off the throttle it brakes to the new speed, reverse, an electric park brake, wiring loom & a differential. Hopefully this helps.
