While swapping the battery on a cheap Chinese e-scooter for fun with a custom-built Panasonic based one (thanks to all the advice here), I started thinking about vehicle form factors that haven't been tried yet (probably b/c they're bad ideas...). One that's crossed my mind is a multi-passenger two-wheeled carriage style vehicle. A silly looking cross between an old style horse-drawn carriage and a hoverboard using the same IMU auto-balancing techniques.
With that idea in mind, I've been musing about the motor/motor-controller I'd need for such a setup. Given that I'm new to all of this, I thought I'd ask what the 2024 recommendations for a motor + motor controller are. Basic requirements:
- 20S voltage (84V) -- or something around there since I've just built this battery pack.
- 3kw-5kw+ motor -- or what ya'll think would be necessary.
- Regenerative breaking
- Cheaper is better
Some questions:
- What are the important features in a motor controller? e.g. FOC, encoder vs. hall, ...
- What motor controllers have great telemetry for a microcontroller to read?
- Having built a quadcopter, is there any difference between an ESC and a motor controller for BLDCs?
- Is there a hub motor + controller that's ready to go for my use case?
- What would be the advantages of a mid-drive?
This is all for fun to motivate my own learning so please don't take the idea too seriously.
