The invention discloses a motor open circuit detection system, an unmanned aerial vehicle and a motor open circuit detection method. The system is electrically connected with a motor, and the system comprises a switch control circuit, a current sampling unit and a driving judgment unit, wherein one end of the switch control circuit is electrically connected with one end of the driving judgment unit, the other end is electrically connected with the motor through the current sampling unit, and the other end of the driving judgment unit is electrically connected with the current sampling unit; the current sampling unit is used for collecting the current of each phase of bridge arm in the switch control circuit; and the driving judgment unit is used for driving the switch control circuit to beconducted and judging whether the motor has an open circuit fault or not according to the current value corresponding to each phase of bridge arm acquired by the current sampling unit. According to the technical scheme, no external equipment is needed for manual detection, whether the motor has an open circuit fault or not can be automatically and accurately judged, and the motor detection efficiency is improved.
