Title:
MAGNETIC FLUID DRIVER
Document Type and Number:
Japanese Patent JP2001333569
Kind Code:
A
Abstract:

To provide a magnetic fluid driver and a drive method which specify, up to the level of practical use, a structure of electromagnet which enables actual use of magnetic fluid as the operation fluid and also assures smooth and highly reliable moving operation of cluster.

In the magnetic fluid driver, in which a plurality of electromagnets, each being formed by winding a coils to iron core forming a magnetic circuit, are provided along the flow path 4, the flow path of magnetic fluid is provided within the magnetic circuit formed by the iron core, and the iron core is provided along the flow path to generate magnetic flux which is almost orthogonal with respect to the flow path, a plurality of first iron cores 5 forming one magnetic pole are provided with a constant pitch in one side along the flow path 4, the coils 7 are wound respectively to the first iron core 5 and a common coupling iron core 8 is also provided to magnetically couple the first iron cores 1 with each other and the second iron cores 6 with each other and also to magnetically couple the first iron cores 5 and the second iron cores 6.
