<p>PURPOSE:To prevent a secondary conductor from contacting to a fixed iron core of a linear motor by stopping a conveying means to the nearest station from a position on which a temperature detecting means is established when output signal from the temperature detecting means is big. CONSTITUTION:A fixed iron core 4 of a linear motor 2 is fixed to feet members 7 on both sides via cramps 6, and still is wound with a stator coil 5. A moving body 3 is arranged with a secondary conductor 10 in fixed, and still supported with rails 9 via wheels 11. When exiting state on the secondary conductor 10 becomes for many hours to rise in temperature of the secondary conductor 10 for reaching to allowed temperature due to continuous running of the moving body 3, color of a thermolabel 21 is changed and change in color is detected by a temperature identifying sensor 20. Thereby, braking force is operated to the linear motor 2 established in a station 1, the moving body 3 is made to stop in the station 1, and when temperature is lowered for reappearing standard color in color on the thermolabel 21, running of the moving body 3 is started again.</p> |
