摘要：An apparatus for controlling cooling of a gantry having a linear motor includes:a stator provided with a first temperature sensor, having a heat sink and a cooling fan atpredetermined portions of an X-axis and an Y-axis linear motors; a mover provided with a
second temperature sensor, having a heat sink installed on the upper surface of an X-axisand a Y-axis linear motors; an encoder for sensing a position and velocity of the mover; anencoder periphery sensor part for measuring surroundings (a temperature, a humidityand a pressure) of the encoder; an A/D converter for receiving a first and a secondtemperature signals and converting them from an analog signal to a digital signal andoutputting the same; a controller for controlling a drive signal outputted from a moverdriver unit to control the velocity of the Y-axis linear motor and the X-axis linear motor; aD/V converter for converting digital signals, that is, a cooling fan control signal and an airvalve control signal to a plurality of drive signals, that is, analog signals; and a moverdriver for providing the drive signal to a coil block.
