The bearing and the sealing washer are respectively arranged between the rotor and the front and back end caps. The front and back magnet exciting coils are wound inside the front and back end caps. The magnetic isolation rings are respectively installed between the front and back end caps and the outer shell, and O-shaped seal rings are respectively arranged between the magnetic isolation rings and the outer shell as well as the front and back end caps. A sealed liquid charging hole is formed at the upper part of the outer shell, and magneto-rheological fluid is filled in a hollow cavity between the stator and the rotor. The front and back magnet exciting coils are wound in the same direction, with the tail ends being connected with each other in series and the head ends being loaded with power sources. The two magnet exciting coils form two parallel magnetic pathways which generate two magnetic fields in opposite direction, and the magnetic flux is generated by a single piece of magnet exciting coils.
