Starting under load requires the motor to generate a starting torque ($T_s$) greater than the static load torque ($T_L$). For mechanical systems like conveyors and mills, the mass remains on the system during startup, causing a constant or increasing torque requirement from the moment of initialization. This typically requires a motor with a high torque-to-inertia ratio or specific starting characteristics, such as high-starting-torque induction motors or DC series motors.

For competitive exams, always identify whether the load is a 'constant torque' or 'variable torque' type. Starting on load usually implies the motor must overcome both static friction and the mechanical load at $\omega = 0$.
