Well, my previuos topic was not clear enough to explain everything. So here is a more clear description of what I want and already have:
I already have one 15t pulley, and a 30t pulley with a 10mm belt. I have 83mm wheels. I would really like it if I could use these pulleys and belt.
I want to be able to start without a push (from a complete standstill), It needs to go 20+ miles per hour on a flat surface at least, and I would like to make it work using the space cell 3 (with enclosure) and the Enertion Vesc. I now know that a 190kv motor wont do the job (https://hobbyking.com/en_us/turnigy-aerodrive-sk3-6364-190kv-brushless-outrunner-motor.html). Could you please advise me with the selection of a motor?
190kV is perfect for the space cell. With that gearing and those wheels your flat ground top speed should be roughly 27mph. Any higher kV would be a bit overkill.
If you have dual motors, starting from a stop shouldn’t be an issue. Their might be some problems with a single motor though. Having sensors motors might help.
A 168kV motor would give a little more torque and your top speed would be around 24mph. I think someone sells a 6374 168kV but I forget who.
Hey dude! You are going to want to bookmark the ESK8 calculator where you can enter your motor KV, battery, and gearing info and it will calculate your top speed and other important information.
