Abstract
Disclosed herein is a stator of a linear motor having a plurality of outer core blocks. Each of the outer core blocks comprises first and second side core blocks and a center core block. The center core block has an inner diameter equal to an outer diameter of a coil block. Consequently, insulation and heat transfer efficiencies are improved, and the size of the linear motor is minimized. Furthermore, the center core block is provided with a heat sink part, which is inserted in the coil block for dissipating heat from the coil block. Consequently, heat generated from the coil block is effectively dissipated.
Claims8
A stator of a linear motor, comprising:
- an outer core including a plurality of outer core blocks;
- an inner core disposed while being spaced apart from the outer core by a predetermined gap;
- a magnet disposed between the outer core and the inner core;
- a bobbin mounted at the outer core;
- a coil wound on the bobbin;
- and
- a coil block mounted at the outer core,
- wherein each of the outer core blocks comprises:
- first and second side core blocks disposed side by side while being opposite to each other;
- and
- a center core block disposed between the first and second side core blocks, wherein a width of the center core block is substantially equal to a width of the bobbin.
