    Motor Stall Times

    Is it a fair assumption that on average, hot and cold stall times for smaller motors (< 30 Hp) are longer than for large motors (> 150Hp)? I have data sheets for 2 newer GE motors (one is stock, other is efficient) and there hot and cold stall times are 65, 77 (stock motor) and 48, 54...

    Motor Torque and High Load Inertia

    I have an old (pre-1970) 15Hp GE motor (sf-1.15, FL Rpm-1770, 550V, FLA-15Amps, Type-K, Nema Design-B, Frame-324Z, Code-G, Insul.-B) that part of a 7.5KVA motor-generator configuration. Attached to the motor end of the shaft is a 430lb. flywheel that provides 260lbs-ft2 of inertia. The...
