I’m building a full custom mountainboard (sort of skatey800 sized). The mechanics are ready, the electronics are the next project. when its finished i will post some photo’s. I did some research, but one point is not clear to me. Maybe someone can explaine the difference to me.
Almost all the builds I read about are using 2 brushless motors with aprox 2500W, which is in total of 5000Watts. For example the skatey800 is using 1 brushed motor of 800W and is still very powerfull, and reaches (by specs) a topspeed of 30km/h. Why is one brushless with 2500W motor than not powerfull enough to power the electric mountainboard? Because the power is more than twice the brushed motor.
I have enough space for placing one bigger brushed motor on my board, and can mount the brushed motor directly on my chain gear. If i choose brushless, I need to make a new gear system, and need probably 2 gears, and two motors. This could be a reason to choose for 1 brushed motor from about 800/1000watts, and combine it with lithium batterys. for example 2x5s batterys and have 37,5V.
What is the big difference, why have 2500w brushless motors not enough power?
(the system including a person will be ± 110 kg, a top speed of 20km/h and range of 10km is a guideline.)
