+This will increase the KV rating by a factor of 1.73 times(√3), but also increase the current consumption by the same factor.
It was successfully tested with this firmware in FOC mode, resulting in a speed increase from 640rpms to 1120rpms with no load, so an increase of the Kv rating from 16 to 28, and a 0.39 Ohm phase to phase resistance, on wheels with 30mm magnets and 5 parallel wires.
-To be checked : Delta wiring is introducing a 30° phase shift, which will result in a much faster speed in one direction when used with Commutation or Sinusoidal control. +To be checked : Delta wiring is introducing a 30° phase shift, which will result in a much faster speed in one direction when used with Commutation or Sinusoidal control. FOC compensates the pase shift. # Links Here are a few interesting builds with hoverboard wheels, you will find many more on Youtube !!!
