WebThe three-phase rewinding has been implemented on a failed SPIM to be compared fairly with the healthy one. The rewound TPIM is fed by a 110V line voltage power supply. The rotating flux loci inside the stator without the rotor is depicted using instantaneous values of the x and y components of the rotating flux obtained by two orthogonal ... WebWhere: Aw=Total cross-section area of the motor winding wire (including the wire insulation) Am=Total cross-section area of all the insulating materials. As=Total cross-section area of the bare slot. Slot Fill Factor: is the ratio of the cross-section occupied by the copper wire inside the stator to the total available area in the bare slot.

WebJul 30, 2024 · During a routine unit shutdown, two aluminum rotor inter-pole supports dislodged and scraped both stator winding and core, causing severe damage to the stator laminations and winding end-turns. Example 2 – The unit is a generator (133 MVA, 16.5 kV, 40 poles) that suffered a phase to ground short circuit (fault near the end of the stator core).
