Title:
ELECTROMAGNETIC PUMP AND FLUID CIRCULATING APPARATUS USING THE SAME
Document Type and Number:
Japanese Patent JP2001119920
Kind Code:
A
Abstract:

To provide an electromagnetic pump, where the fastening of its laminated core to it required during its operation and its transportation is performed, and the heat removing quality of the heat generation of the inside of its stator which is preformed by the conductive fluid can be improved, and further, the stable flow of sodium can be performed.

With an outside duct 3 and an inside duct provided concentrically, the space between them is used as the passage of a conductive fluid, and an outside laminated core 6 is disposed on the outer peripheral side of the outside duct 3, and an inside laminated core is disposed on the inner peripheral side of the inside duct. By fitting respectively stator coils 8 into the respective slots of the outside laminated core 6, a progressive magnetic field is formed is the passage of the conductive fluid existing therein. Side plates and an alignment plate 15 are formed respectively out of the materials having nearly equal thermal expansion coefficients to each other. The side plates interpose between them both the laminar-direction ends of the laminated core 6. The alignment plate 15 determines the circumferential, radial, and axial positions of the respective blocks of the laminated core 6, by fastening to the laminated core 6 these side plates from the outer periphery of the laminated core 6.
