This motor is capable of two cold or one hot start with a maximum connected load inertia of 808 Lb-Ft Sq (34.02 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 40 seconds. Safe stall time at 100% voltage is 91 seconds cold, 48 seconds hot. Rotor inertia
is 48.07 Lb-Ft Sq (2.02 Kg-meter Sq).
