I’ve been thinking about using an alternator as a motor for a go-cart for a number of years. There have been a lot of recent projects, including a few popular videos on YouTube.
However I started looking into higher voltage alternators and eventually into the category of “alternators” for mild hybrids, which use a 48v battery for stop start and power assist. I just got a heck of a deal on a Ram truck unit for their V6 models and will likely be trying to use this for either a go-cart or an electric riding lawnmower.
I’ve found some interesting details. The unit I got looks to be made by Continental, is liquid cooled and appears to have an integrated controller. I’ve found some specs on it on various press releases and whatnot. Seems to be in the 5-7 KW continuous and up to 15KW peak output range and 90 lb/ft of torque for this model:

The controller is likely similar to or actually this Infineon unit:

What’s interesting is Continental seems to have adapted this motor for the Electric scooter market:

The picture of the motor on the table looks nearly identical to the one I purchased.
I haven’t received mine yet, but will post more info here once I do and what I figure out with it. I don’t have high hopes for using the built in controller. But I’m betting it has Hall sensors.
Has anyone else worked with these or explored them? Since these systems have achieved a fair amount of adoption there is going to be a decent supply on the salvage market. Might be a good source for mid-power motors at a decent price. If the controllers could be figured out it would be a slam-dunk.
