Abstract
Disclosed herein is an outer core assembly structure of a linear motor. At least one of a plurality of core sheets is an extended core sheet having a length greater than that of the other core sheets. Consequently, easy and convenient alignment of first and second outer core blocks is accomplished when the first and second outer core blocks are assembled, and the first and second outer core blocks are securely fixed to each other. Furthermore, an additional reinforcing cover is not necessary. Consequently, assembly of the first and second outer core blocks is easily and conveniently accomplished, and therefore, the assembly costs are reduced.
Claims19
An outer core assembly structure of a linear motor, comprising:
- at least one outer core, the at least one outer core including first and second outer core blocks opposite to each other, the first and second outer core blocks being composed of a plurality of stacked core sheets, respectively;
- and
- a coil mounted at the at least one outer core, wherein
- at least one of the core sheets positioned on outermost sides of one of the outer core block is an extended core sheet having a length greater than that of remaining core sheets of the one of the outer core blocks,
- wherein the core sheets except the core sheets positioned on the outermost sides of the one of the outer core blocks have a same length.
An outer core assembly structure of a linear motor, comprising:
- at least one outer core, the at least one outer core including first and second outer core blocks opposite to each other, the first and second outer core blocks being composed of a plurality of stacked core sheets, respectively;
- and
- a coil mounted at the at least one outer core, wherein
- at least one of the core sheets positioned on outermost sides of the outer core blocks is an extended core sheet having a length greater than that of the other core sheets, and
- another one of the core sheets positioned on the outermost sides of the outer core blocks is a reduced core sheet having a length less than that of the other core sheets,
- wherein the other core sheets have a same length.
An outer core assembly structure of a linear motor, comprising:
- a plurality of outer cores, each of the outer cores including first and second outer core blocks opposite to each other, the first and second outer core blocks being composed of a plurality of stacked core sheets, respectively;
- an inner core disposed while being spaced a predetermined gap from the outer cores;
- a bobbin, at which the outer cores are radially disposed;
- and
- a coil wound on the bobbin, wherein
- at least one of the core sheets positioned on outermost sides of one of the outer core blocks is an extended core sheet having a length greater than that of remaining core sheets of the one of the first and second outer core blocks, wherein the remaining core sheets except the core sheets positioned on the outermost sides of the one of the outer core blocks have a same length.
