Description of induction motor faults.
| | Type of faults | Fault description |
| | Angular misalignment fault (AMF) | Angular misalignment is the effective angle between the two shaft centerlines, the angle between the shaft centerlines is 0.48° |
| | Broken rotor bar fault (BRBF) | Among 34 rotor bars, 12 rotor bars are involved in the plastic deformation of the grinding furrow: 5 mm in diameter and 15 mm in depth |
| | Parallel misalignment fault (PMF) | The offset between two centerlines of the motor and load has been changed 0.1 mm |
| | Rotor imbalance fault (RIF) | Unbalance mass of 15.64 g cm is added at the right end of the rotor |
| | Bearing fault (BF) | A spalling on the outer race of the bearing is replicated |
| | Bowed shaft fault (BSF) | The shaft is slack in the middle (0.075 mm), which causes dynamic air-gap eccentricity |
| | Phase imbalance fault (PIF) | 4.3 resistance is connected to one of the three-phase wires of the induction motor |
