*1 This shows a value measured when the Motor Coil Unit is at 100°C and the Magnet Track is at 25°C. As a
cooling condition, attach the Motor Coil Unit to the center of an aluminum radiator plate (moving table) of the
specified dimensions, shown in the above table.
*2 The Motor Coil Unit is subjected to a temperature rise of 6 K/s.
