Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in fig. 1 and 2, a parallel permanent magnet governor includes a conductor rotor assembly (1), a permanent magnet rotor assembly (2), and a governor (3). The conductor rotor assembly (1) and the permanent magnet rotor assembly (2) are both of a two-stage parallel structure, and the conductor rotor assembly (1) and the permanent magnet rotor assembly (2) are concentrically and crossly sleeved. The conductor rotor assembly (1) comprises a first-stage conductor ring (11), a second-stage conductor ring (12) and a supporting disc (13), wherein the first-stage conductor ring (11) and the second-stage conductor ring (12) are concentrically sleeved, fixed on the supporting disc (13) through end faces, uniformly arranged along the radial direction of the supporting disc (13), and sequentially provided with the first-stage conductor ring (11) and the second-stage conductor ring (12) from the excircle to the circle center. The permanent magnet rotor assembly (2) comprises a primary permanent magnet ring (21), a secondary permanent magnet ring (22) and a support frame (23), the primary permanent magnet ring (21) and the secondary permanent magnet ring (22) are concentrically sleeved, fixed on the support frame (23) through end faces, uniformly arranged along the radial direction of the support frame (2-), and the primary permanent magnet ring (21) and the secondary permanent magnet ring (22) are arranged from the outer circle to the circle center in sequence. The primary conductor ring (11) is opposite to the primary permanent magnet ring (21), and the secondary conductor ring (12) is opposite to the secondary permanent magnet ring (22).

The adjuster (3) is connected with the permanent magnet rotor assembly (2) to adjust the axial position of the permanent magnet rotor assembly (2), so that the meshing area of the permanent magnet rotor assembly (2) and the conductor rotor assembly (1) is changed. Because the conductor rotor subassembly (1) and the permanent magnet rotor subassembly (2) are of a parallel structure, the permanent magnet rotor subassembly (2) and the conductor rotor subassembly (1) can be completely separated by only moving the permanent magnet rotor subassembly (2) by the width of one conductor ring without influencing each other, so the speed regulation range is wide.
