Abstract
An axial permanent magnetic gear capable of bi-directional excitation belongs to the technical field of permanent magnetic gears. The axial permanent magnetic gear capable of bi-directional excitation solves a problem that a conventional permanent magnetic gear is difficult to manufacture and install. The axial permanent magnetic gear capable of bi-directional excitation comprises two rotors, a stator and a rotating shaft. The stator and the rotors adopt an axial structure. Permanent magnets for excitation in the radial and axial directions are arranged on magnetic steel for magnetic conduction in the radial and axial directions of each rotor, so that magnetic fields generated by the permanent magnets for excitation in the two directions cannot affect each other, torque transmitted by the gear is increased without increasing the size of the whole gear and changing a transmission ratio, thereby increasing the torque intensity of the whole gear.
