This motor is capable of two cold or one hot start with a maximum connected load inertia of 5350 Lb-Ft Sq (225.24 Kgmeter Sq)at 100% voltage, where the load torque varies with the square of the speed. Acceleration time with maximum
inertia and the above load type is 42 seconds. Safe stall time at 100% voltage is 82 seconds cold, 51 seconds hot. Rotor
inertia is 77.95 Lb-Ft Sq (3.28 Kg-meter Sq).
