  "textContent": "The invention discloses a power system, a power system control method, an unmanned aerial vehicle (UAV) and a UAV control method. The power system includes engine, motor, and battery. The engine comprises an engine body and an engine output shaft. The motor comprises a stator, a rotor, and a stator connector for connecting the stator and the rotor. The stator connector is arranged on the engine body, and the rotor is coaxially arranged on the engine output shaft. The rotor is used for coaxial connection with the external power receiver. The battery is connected to the motor, and the battery can be discharged to provide electric energy to the motor, or receive the electric energy output by the motor for charging. The power system of the invention sets the rotor of the motor, the external power receiver and the engine output shaft as coaxial connection, and the motor can be used as a generator to charge the battery by doing negative work on the engine output shaft, or as an electric motor to do positive work on the engine output shaft for power output, thereby realizing high energy utilization and power redundancy.",
