This motor is capable of two cold or one hot start with a maximum connected load inertia of 1876 Lb-Ft Sq (78.98 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 23 seconds. Safe stall time at 100% voltage is 55 seconds cold, 27 seconds hot. Rotor inertia
is 47.44 Lb-Ft Sq (2 Kg-meter Sq).
