The invention provides an electric rotorcraft. The electric rotorcraft is characterized in that the electric rotorcraft comprises a rack, a propeller motor, a pre-rotating motor and a battery pack, arotor disc is arranged at the top of the rack, a rotor wing is mounted at the top of the rotor disc, the pre-rotating motor for assisting a rotor wing to rotate is arranged on the rotor disc, the propeller motor is arranged in the middle of the rack, propellers are installed on the propeller motor, an empennage is arranged at the rear end of the bottom of the rack, the battery pack is arranged inthe center of the bottom of the rack, and the propeller motor and the pre-rotating motor are both electrically connected with the battery pack. Compared with electric rotorcrafts in the prior art, theelectric rotorcraft of the invention, taking electric power as power to drive the propellers, making the motor drive rear wheels to assist in sliding and pushing to assist in flying and using the motor as power to assist pre-rotating blades, obtains initial lifting force, is separated from the ground as soon as possible to lift off, has the advantages of small size, light weight, low environmentrequirement during takeoff, simplicity in operation, and high safety, and meets the green and environment-friendly requirements.
