Four positioning plates are symmetrically arranged at each end of the ring cover. The positioning plates are movably hinged at the ends of the ring cover. Limiting bolts that are inserted into the ends of the stator half tubes are passed through the positioning plates.

[0024] Two semi-circular stator half tubes are joined together to form a cylindrical stator tube. The rotor tube is located inside the stator tube, while the ring cover is fitted on the outside of the stator tube. The two ends of the ring cover are fixedly connected to the two ends of the stator half tube using positioning plates and limiting bolts, thus fixing the stator tube inside the ring cover.

[0032] The stator wire is fixed on the outer wall of the stator half tube and extends to the outside of the stator tube, and a plurality of wire brushes connected with the stator wire are fixedly installed on the inner wall of the stator half tube, and the other end of the wire brush is attached to the outer wall of the conductive rail.

[0033] The wire brush is attached to the outer wall of the conductive rail, the wire brush keeps in contact with the conductive rail when the rotor tube rotates in the inside of the stator tube, and the stator wire keeps in communication with the rotor wire.

[0034] The positioning piece is arranged in a fan shape and is movably hinged at the edge of the stator tube through a hinge shaft, and the two ends of the positioning piece are respectively attached to the outer walls of the two stator half tube end portions.

[0035] On the same positioning piece, the number of limiting bolts is two, and the two limiting bolts are respectively inserted into the outer walls of the two stator half tube end portions.
