140kW Low Noise Permanent Magnet Generator 400V 1500rpm for Genset PMSG
This 140kW low noise permanent magnet generator is a four pole PMG alternator running at 1500rpm for 50Hz standby and prime power gensets. Without excitation winding and slip rings the alternator runs quieter and cooler, which helps the complete genset meet strict residential and hospital noise limits.
Key Features
- Noise level below 75dB(A) at 1m, suitable for noise sensitive sites
- No excitation system, AVR or slip ring, reducing failure points of the set
- Fast voltage response and high overload capability for motor starting loads
- Balanced three phase 400V output with low harmonic distortion
- Compact 4 pole frame easy to couple with standard diesel engine bell housing
