Small Cooling Fan improved heat dissipation

DIY multifunction "Small Cooling Fan", a large arc deflector frame, circuit fault (no-load speed is too high resulting in a short circuit of the inverter bridge burned) Delta FFB0812SH taken by sickle blades and extra-heavy-magnetic metal chamber (to solve the problems caused by bad vibration balancing), "Small Cooling Fan" split out of the brushless motor rotor rubber bonded NdFeB magnets and single-phase brushless motor stator DIY hand around two strands in parallel with the commutation coil, DIY as "iOS雷竞技 " brushless motor drive circuit (DIY external temperature sensor can be more precise temperature control in the best location).
