# Delta wiring
Hoverboard wheels can be rewired from Star to Delta to trade Torque for Speed.<br>
This will increase the KV rate by a factor of 1.73 times(√3), but also increase the current by the same factor.<br>
This will increase the KV rating by a factor of 1.73 times(√3), but also increase the current consumption by the same factor.<br>
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.<br>
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.
