High -speed magnetic suspension electric motor rotor damping mechanism based on magneto rheological damper

The utility model discloses a high -speed magnetic suspension electric motor rotor damping mechanism based on magneto rheological damper, including magnetic conduction ring, coil pack and have the stationary screen of axle center through -hole. The coil pack is located the central authorities of magnetic conduction ring, and the both ends of coil pack are connected with the support column respectively, install the magnetic conduction roller on the support column, and the support column passes the axle center through -hole of stationary screen and adopts the fixed pin subassembly fixed. High -speed magnetic suspension electric motor rotor damping mechanism based on magneto rheological damper through the active control to coil current, changes the size through magnetorheological suspensions's magnetic field under the working condition of difference to change magnetorheological suspensions's performance of stiffness and dampness, reach the effect of shock attenuation supporting.
