The torque rating of 5 kg.cm for a DC geared motor indicates the maximum torque the motor can exert at a distance of one centimeter from its axis. This means the motor can theoretically handle a load of up to 5 kg, but actual load capacity depends on factors like RPM and the motor's efficiency. Torque is inversely related to RPM; as RPM increases, torque decreases. Proper conditions, such as ensuring the motor is not overloaded and maintaining optimal operating speeds, are crucial for performance. Understanding these parameters is essential for effective motor application.
