The invention relates to an electric-driven unmanned helicopter which comprises a helicopter body, a tail beam, a speed reducer, a power battery pack (1), a motor and a motor controller. The power battery pack (1) can supply power for the motor controller (2) through two wires b (6); the motor controller (2) is connected with the motor (3) through three wires a (5) and can supply power for the motor (3), so that the motor (3) can be driven to rotate; the motor controller (2) can change the current size through a multiphase staggered parallel-connection Buck circuit, so that the rotating speed of the motor can be changed, the variable speed output of the helicopter in a full-power state can be obtained, and the cruise efficiency at low blade tip speed is improved. Meanwhile, the fuel consumption of the electric-driven helicopter is eliminated, and the noise of the helicopter is reduced.
