Document Type and Number:
Japanese Patent JP2007014181
Kind Code:
A
Abstract:
To provide a compound magnetic substance driving device driven by a compound magnetic substance comprising a permanent magnet having a strong magnetic force such as a neodymium magnet or the like and an electromagnet.
In the compound magnetic substance driving device, a permanent magnet is fitted to the magnet core of the electromagnet. and a permanent magnet with its one pole cut-off is arranged on the side. The polarity of the electromagnet is reversed and the magnetic force balance between the magnetic core and the permanent magnet with its one pole cut-off changes to drive the compound magnetic substance driving device.
