The correct equation that represents the dynamics of a rotating system is $J \frac{d\omega}{dt} = \text{Motor torque} - \text{Load torque}$. This equation is derived from Newton's second law for rotation, where the net torque on a system is equal to the moment of inertia times the angular acceleration ($J \frac{d\omega}{dt}$). The net torque is the difference between the motor torque (driving torque) and the load torque (resisting torque).
