Abstract
The present invention provides a cooling mechanism between a linear motor rotor and a platform coupled thereto, characterized essentially in that a cooling portion is provided between the rotor and the platform, and further in that heat transfer is blocked between the cooling portion and the platform, thereby preventing heat received by the cooling portion during heat dissipation from being transferred to the platform, so as to ensure the precision of the platform.
