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, which comprises an inner rotor, a magnetic adjustment block, a winding and an outer rotor. The beneficial effects of the present invention are: armature windings are added to the gaps between the magnetic adjustment blocks, the interaction between the magnetic field generated by the winding current and the magnetic field generated by the outer rotor permanent magnets generates electromagnetic torque and the permanent magnets on the inner and outer rotors generate The permanent magnet torque generated by the interaction between the magnetic fields acts together to achieve the purpose of controlling the outer rotor. In the case of sudden changes in the load torque, target speed and position of the outer rotor, the electromagnetic torque generated by the armature winding is used to plan the outer rotor. The change motion curve of speed and position enables it to move freely at different target speeds and positions and minimize speed fluctuations. When the load torque exceeds the maximum torque that the magnetic gear itself can generate without armature current, it will The energization of the armature winding is one of the sources of the outer rotor torque, which expands the operating range of the entire magnetic gear system, that is, the torque output capability.

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...
