<P>PROBLEM TO BE SOLVED: To provide a motor device which can be handled safely, even if it is equipped with a regenerative resistor. <P>SOLUTION: In a regenerative resistor temperature indicator 16, which displays the temperature of a regenerative resistor 15 of a motor device 1, a thermoelectric module 21 converts the heat generated at regenerative power consumption by the regenerative resistor 15 into an electric power, corresponding to the temperature of the regenerative resistor 15. The power supply part 22 of the regenerative resistor temperature indicator 16 utilizes the power, resulting from conversion by the thermoelectric module 21, to illuminate a red LED 232 of a display part 23, for displaying the temperature of the regenerative resistor 15. According to the configuration, even if the power supply of the motor device 1 is cut off, the temperature of regenerative resistor 15 is displayed on the display part 23, to allow an operator to discriminate whether the regenerative resistor 15 is in danger, resulting in safe handling of the motor device 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
