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> 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>
