Title:
ELECTROMAGNET DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/132531
Kind Code:
A1
Abstract:
An electromagnet device where, even if a large number of wire windings and layers must be wound around a bobbin, a predetermined number of windings can be reliably wound in each layer with good workability, enabling overall dimensions of the device to be easily kept within a predetermined range. The electromagnet device has a core, the bobbin installed on the outer periphery of the core, and the wire wound around the bobbin. A grooved part in which a guide groove for guiding the wire along a winding position is formed is installed on the bobbin. A winding surface on which the wire is wound is formed by both the bobbin and the grooved part.
