This motor is capable of two cold or one hot start with a maximum connected load inertia of 1029 Lb-Ft Sq (43.32 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 35 seconds. Safe stall time at 100% voltage is 89 seconds cold, 52 seconds hot. Rotor inertia
is 6.1 Lb-Ft Sq (0.26 Kg-meter Sq).
