Abstract
A drive guide device capable of effectively releasing heat produced by a mover. The drive guide device has a movement unit 100 moved by a linear motor while being guided by a rail 230. The movement unit 100 has the mover 140 to which electricity is conducted to produce a magnetic field, a table 110 placed on the mover 140 on the opposite side of a base 210 to which the rail 230 is fixed, a heat sink 130 having heat radiation fins for releasing heat produced by the mover 140 and placed between the mover 140 and the table 110, and a heat transmission route for transmitting heat, which cannot be released by the heat sink 130, to the table 110. The table 110 is made from a material having a low thermal expansion coefficient.
Claims6
A drive guide apparatus having a movement unit which moves by being guided along a guide, by a linear motor,
- the movement unit comprising:
- a movable element for generating a magnetic field when energized, and
- a table provided on the side opposite to a base to which the guide is fixed, of the movable element, and
- the apparatus having, between the movable element and the table, a radiating structure for radiating heat generated by the movable element,
- wherein a heat transmission route for transmitting heat which cannot be released in the radiating structure to the table is provided, and
- the table is made of a material having a low thermal expansion coefficient.
