The torque rating of 5 kg.cm for a DC geared motor indicates that the motor can exert a force sufficient to lift a 5 kg weight at a distance of 1 cm from the axis of rotation. This means that the motor is not designed to handle a load of 5 kg directly; rather, the torque value is a measure of its rotational force. Torque is indeed related to RPM, as higher RPMs can reduce the effective torque available for lifting loads. Understanding these relationships is crucial for selecting the appropriate motor for specific applications.
