Electric driver and air vehicle and ship applying same

Abstract

The invention provides an electric driver for an air vehicle and a ship. The electric driver comprises a motor output shaft; the electric driver further comprises a first rotor system, a second rotor system and a synchronous output system; the first rotor system comprises a first rotor and a first stator which are coaxially arranged; the second rotor system comprises a second rotor and a second stator which are coaxially arranged, and the first rotor and the second rotor are coaxially arranged; the synchronous output system comprises a sun gear, planet gears, planet carriers and a gear ring; the planet gears surround the sun gear and are meshed with the sun gear; the gear ring is arranged outside the planet gears in a sleeving mode and meshed with the planet gears; the planet gears are supported on the planet carriers; the sun gear, the gear ring and the planet gears have a two-input one-output relation, that is to say, any two of the sun gear, the gear ring and the planet gears are driven by the first rotor and the second rotor to rotate respectively, and the rest one is fixedly connected with the motor output shaft. According to the electric driver, by arranging the synchronous output system, rotating of the first rotor and rotating of the second rotor are synchronously output to the motor output shaft, mutual counteracting of output torque of the first rotor and the second rotor is avoided, the motor efficiency is significantly improved, and not only is the power higher, but also energy is effectively saved. The invention further provides the air vehicle and the ship applying the electric driver.
