Abstract

The invention discloses an outer rotor rotary type magnetic fluid travelling wave pump, relating to a magnetic fluid travelling wave pump. The invention solves the problem that there is no outer rotor rotary type magnetic fluid travelling wave pump used for analyzing characteristics of motion of magnetic fluid affected by travelling wave magnetic field at present. The rotor is fixed on a permanent magnet in a sleeved manner, the permanent magnet consists of permanent magnetic single bodies with an even number magnetizing along an axial direction, and the magnetizing directions of two adjacentpermanent magnetic single bodies are opposite; a stator consists of two magnetic separation sheets, a magnetic conductive iron core and a second non-magnetic conductive shaft, the magnetic iron core is fixedly arranged on the second non-magnetic conductive shaft, a coil pipe is sleeved on the magnetic conductive iron core, two side end faces of the magnetic conductive iron core are both provided with the magnetic separation sheets, the stator and the coil pipe are both arranged in a cylinder, and the magnetic fluid is filled in the coil pipe. The invention provides the outer rotor rotary typemagnetic fluid travelling wave pump by using the magnetic fluid kinetic principles. By adopting the invention, the carrying characteristics of the magnetic fluid can be validated, thereby a new fieldof the magnetic fluid application is developed.
