mikep just let me know when you want one.
hx 40, bobxyz: that is the motor I have right now. If adding hall sensor stuff is as easy as hx 40 hinted at, I would like to go that way as everything is exposed in this motor. It makes it easier for someone like me understand what is going on. From what I gather, with the hall thingie it would behave the same as, say, a Honda Insight motor. So, the MC33035 could be used to control it. I need to order the other components though, and then have a raspberry pi or even arduino control it so I can get experience without spending too much money or space. hx 40 mentioned (and I think the datasheet supported him) it can control higher voltage/current motor by having it control the components which will connect directly to the motor; we will cross that bridge when we get there.
Swedishbrick, something you may want to consider is weight:
- The B230 should weight 150Kg (~330lb) with the accessories (

- An AW71 weights some 68-70Kg (~150lb) (

- 14 gallons of fuel weights 40Kg (~90lb)
So, for an automagic RWD Volvo, you have 260Kg to play with without affecting handling. If you can find batteries and an Ev powertrain that weights about that, your Volvo will not know any better. Of course the reality is the batteries will add more to have some reasonable range.
For reference
- Insight (hybrid)
- batteries : 30kg (65lb)
- Motor 19.6kg (43.5lb)
- Engine 108 kg (238lb) dry
- Transmission something kg
- Nissan leaf (Ev)
- batteries : 300 kg (661lb)
- Motor 58kg (128lb)
Which leads to: I was reading about the different kinds of batteries and they all have their issues and features. If anyone with more experience can correct me, please do.
- NiMH has memory does not have the power density of Lithium but can be reconditioned to last almost as long as a lead acid.
- Lithiums cannot be reconditioned, and their manufacturers give like a year warranty at most. And yet Tesla/Leaf cars have been out in the wild for a while and their batteries do not go bad after a year.
