Problems solved by technology

[0003] The magnetic gears used now are mainly passive magnetic gears. For the traditional passive magnetic gears, the position accuracy will be reduced due to torque fluctuations, and the problem of step loss is easy. Therefore, the present invention proposes an automatically controlled active magnetic gear. gear,

Abstract

The invention discloses an automatically-controlled active magnetic gear. The active magnetic gear comprises an inner rotor, magnetic adjusting blocks, a winding and an outer rotor. The beneficial effects of the invention are that the armature winding is added in the gap between the adjustable magnetic blocks, and through the electromagnetic torque generated by the interaction between the magnetic field generated by winding current and the magnetic field generated by the permanent magnet of the outer rotor and the permanent magnet torque generated by the interaction between the magnetic fields generated by the permanent magnets on the inner rotor and the outer rotor act together, the purpose of controlling the outer rotor is achieved; under the condition that the load torque, the target rotating speed of the outer rotor and the position change suddenly, the electromagnetic torque generated by the armature winding is used for planning the rotating speed and position change motion curve of the outer rotor, so that the outer rotor can stably and freely move at different target rotating speeds and positions, and the rotating speed pulsation is reduced as much as possible; when the load torque exceeds the maximum torque which can be generated when the armature current is not applied to the magnetic gear, the armature winding is electrified to serve as one of the sources of the torque of the outer rotor, and the operation range, namely the torque output capacity, of the whole magnetic gear system is expanded.

Description

technical field [0001] The invention relates to a magnetic gear, in particular to an automatically controlled active magnetic gear, which belongs to the technical field of gears. Background technique [0002] Magnetic gears use magnetic force to drive, which is gear meshing without mechanical contact. It is precisely because of the non-contact meshing between the gears, no frictional energy consumption, and stable transmission that the magnetic gears have the advantages of high efficiency, high reliability and long service life. Secondly, it does not need to be lubricated, clean, oil-free, dustproof and waterproof. And it has the function of overload protection, the reducer will not be damaged when overloaded, and the transmission relationship will be cut off at any time when overloaded, not only the reducer itself will not be damaged, but also the prime mover can be protected. [0003] The magnetic gears used now are mainly passive magnetic gears. For the traditional pass...
