Through this video you will learn what the kv value is, what affects kv and how to select a brushless motor using the kv value.

A brushless motors kv value is one of the most important parameters that you can use to select a motor. Kv tells us the amount of RPM per volt that a motor will provide. Knowing kv of a brushless motor will allows us to select a motor that can provide an adequate amount of output RPM.

Tell us Step-by-Step how to rewind the stator and the proper way to change the rotor for a given KV and/or performance for an intended purpose for a Brushless Motor, please. This is for us who are curious and a little more advanced technically. Thank you.

Just came across your channel. Thanks for the info. What esc/motor combo would you recommend for a Losi Drag car roller? I currently have an unused castle sidewinder sv3 combo 3800kv. Thoughts?

Great! Can you share the analitical formulas and all calculations for designing the BLDC?
Maybe some book with example of designing some motor. Or there is a online calculator, where I can obtain the dimensions of stator, rotor, aor gap, and winding turns, poles number, and slot numbers for concrete power and speed.
Thank you!

What outrunner motor is used in this video? And would you use yourself an outrunner motor on a drag car which sees bout 20-30 sec max throttle.punches on a drag strip?
