PURPOSE:To prevent the occurrence of demagnetization phenomena by breaking a current application breaker thereby stopping it in case that an electric motor used under low-temperature circumstance falls below limit demagnetizing temperature or operating a heating means thereby settling the used temperature. CONSTITUTION:A temperature sensor or a thermostat 102 measures and detects the temperature or a servo motor 101 or its peripheral temperature, and sends its temperature signal to a robot controller 103. A heater controller 105 and a breaker controller 104 are connected to the robot controller 103, and the servo motor 101 is heated by operating a heater through the heater controller 105 from the robot controller 103, according to a temperature signal, or it is set in operation pause condition or break condition by cutting or controlling the breaker through a breaker controller 104. Accordingly, it becomes possible to use it without causing demagnetization phenomena even under extreme low temperature circumstance. |
