This motor is capable of two cold or one hot start with a maximum connected load inertia of 4518 Lb-Ft Sq (190.21 Kgmeter 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 37 seconds. Safe stall time at 100% voltage is 143 seconds cold, 69 seconds hot.
Rotor inertia is 98.27 Lb-Ft Sq (4.14 Kg-meter Sq).
