We recommend 12s for these hubs. I’m sure you could do much higher also, theres nothing really stopping you.
1500 watts per motor in 4wd is where I start to lose traction on hard accelerations, so if you really need every little bit of power, theres always that option.
In terms of how much power these motors can take, it’s really unknown at this point. I think 1500w con is a conservative number.
At the end of the day, what makes a motor powerful and to be able to handle high current and high amps:
- Small air gap (check)
- Large stator (check)
- Lots of copper (check)
- Big and powerful magnets (check)
- Ultra low winding resistance (check)
- High heat components in case things do get hot under high loads (check)
In terms of size, these are larger than most outrunner motors. Bigger stator, more copper, and a lower winding resistance. Everything in the motor is rated to at least 300 F, most parts are rated to 400 F, though I wouldn’t recommend getting them close to there. If you really want the power, 4wd is a better way to go anyways. Don’t think the focbox or any vesc can reliably do 80a con anyway. You do less stress on the motors and esc’s also. I think 3000w con is more than enough for most who want a dual drive hub motor. That’s 10x the power output of those cheaper china hub motors.
The only outrunners I expect will beat these hub motors will be 80mm outrunners. Those guys have a much larger stator, larger magents, ect, and a hub motor made for air filled tires would be the only way you could compete with those things. Even then, I beat Dereks 80mm motors off the line 3/3 times. Only time will tell!
