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.

Description

technical field [0001] The invention relates to an electric drive device and an aircraft and a ship using the same. Background technique [0002] The dual-rotor motor has two mechanical shafts, which can realize the independent transmission of energy of the two mechanical shafts, and has good application prospects in fields such as hybrid electric vehicles and continuously variable transmissions. [0003] Chinese patent application 200610015892.8 discloses a double-stator double-rotor motor. On the other side of the bearing, piezoelectric ceramic sheets, stator elastic bodies, and rotors are symmetrically arranged, and are connected to the shaft by springs and nuts. Stainless steel is processed into The R-shaped transition shape stator is elastic body, the piezoelectric ceramic sheet is pasted on the back to make the stator, the two stators and the bottom plate are connected together by bolts, the friction material is processed into the rotor, and the stator is connected by ...
