CRRC Permanent Magnet Synchronous Generator Wind Turbine
CRRC permanent magnet synchronous generator (PMSG) product portfolio covers three technical routes: large-capacity offshore semi-direct drive, compact integrated semi-direct drive and low-speed full direct drive, with rated power ranging from 1.5 MW to 7.6 MW. The product line is applicable to inland onshore wind farms, coastal salt-fog zones and harsh offshore marine operating environments.
Semi-direct drive models adopt optimized matching with medium-speed gearboxes, compact dual cooling structures and integrated bearing layout to cut nacelle space occupation, reduce overall system weight and maintenance workload; direct drive units connect directly with wheel hubs, eliminating gearboxes to simplify transmission chains, lower mechanical loss and improve long-term operational reliability. All models work with full-power PWM converters to deliver high-quality grid electricity, featuring outstanding low voltage ride-through capability and grid adaptability. Customized cooling, anti-corrosion and low-temperature reinforcement options are available to satisfy diverse wind farm construction demands across different regions.
