文摘
- •
Localized bearing faults can be detected under variable speed operation.
- •
Vibration spectral analysis is used to detect single-point defects in PMSG.
- •
Under variable speed conditions, a tacho-less resampling strategy is proposed.
- •
The vibration signal is resampled at constant rotor position intervals.
- •
Rotor position is estimated from a PLL using the measured stator voltages.
