I’m thinking about converting an old delivery truck from the late 40s they don’t make parts for anymore. The problem is the vehicle is HEAVY by modern standards (could barely move it with the skid steer) I’m starting my parts list from the ground up and want to use hub motors. Any suggestions for hub motors that are potentially up to the task would be appreciated.
While I will echo the ‘don’t use hub motors’ idea. The idea does have it’s merit. You will need a different approach to things though.
Here is a company that makes hub motors. And the direct link to the appropriate product. Specifically their 12kw hub motor, which appears to be the most powerful option currently available. It appears they can make it with a rim already installed.
You’ll NEED two to get the vehicle to move, but you’ll WANT four for better performance. I recall seeing an ‘at speed’ power draw graph for most electric cars, and highway speeds need roughly 20 to 30 kilowatts continuous to maintain speeds.
Controller dependent, one controller per hub motor, Your system should probably be at 96v nominal. These are the ones the above company recommends, but there are other options out there.
One controller per motor, have them all hooked up to the same digital accelerator pedal.
All in all, I would expect about 5000 USD per wheel in costs, not including batteries.
