This motor is capable of two cold or one hot start with a maximum connected load inertia of 85 Lb-Ft Sq (3.58 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 24 seconds. Safe stall time at 100% voltage is 47 seconds cold, 28 seconds hot. Rotor inertia
is 1.27 Lb-Ft Sq (0.05 Kg-meter Sq).
