This motor is capable of two cold or one hot start with a maximum connected load inertia of 650 Lb-Ft Sq (27.36 Kg-meter
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 30 seconds. Safe stall time at 100% voltage is 83 seconds cold, 36 seconds hot. Rotor inertia
is 50.39 Lb-Ft Sq (2.12 Kg-meter Sq).
