<P>PROBLEM TO BE SOLVED: To prevent a driven device driven by a gear motor from being broken, by a simple configuration without requiring an exclusive and high-cost controller to the driven device. <P>SOLUTION: The gear motor G includes a motor 100 and a reduction gear 101, and has predetermined thresholds (B), (C) less than a rated current equivalent value (A) that outputs a rated torque of the motor 100. A monitor means 105M detects that a current I flowing through the motor 100 exceeds the predetermined thresholds (B), (C) less than the rated current equivalent value (A). A driven device protector 105 performs at least one of issuing warnings BO, CO, or interrupting the current I flowing through the motor 100, when the current I flowing through the motor 100 exceeds the predetermined thresholds (B), (C). <P>COPYRIGHT: (C)2011,JPO&INPIT |
