Abstract
The utility model provides a permanent magnet speed controller, comprising a cage type conductor rotor, a permanent magnet rotor, a fixed rotor and an adjusting mechanism, wherein the cage type conductor rotor surrounds the permanent magnet rotor; the permanent magnet rotor is opened and closed along the axial direction through the adjusting mechanism; the adjusting mechanism is connected with the fixed rotor; and the fixed rotor is connected with the permanent magnet rotor through a gear-rack mechanism. The action area of the permanent magnet speed controller is an air gap between a conductor ring of the cage type conductor rotor and an annular magnetic base of the permanent magnet rotor, so that no axial force exists. Therefore, the push-pull force required by the adjusting mechanism is small. Without the influence caused by the axial force, the permanent magnet speed controller is simpler in installation, wider in work range and applicable to the working condition having the axial clearance. Symmetrical air inlets are formed by a left fixing board and a right fixing board of the cage type conductor rotor. Under the effect of a centrifugal force, cool air is introduced into a cooling duct of the air gap between the conductor ring and the permanent magnet rotor of the cage type conductor rotor so as to carry out the mandatory cooling.
