Webb19 juni 2024 · Locked rotor performance encompasses the motor characteristics related to when a motor is in a locked (stalled) condition, such as at initial energization. Locked rotor performance is affected by combinations of the motor design, driven-load characteristics and onsite conditions. Webb1. The magnetization current of an AC motor would be that current that flows into the stator should the rotor be removed. It's difficult to measure for that reason because any amount of movement/loading of/on the rotor is going to affect it. Like a transformer, an AC induction motor has an equivalent circuit and it is sensible (for both motor ...
