CRRC CDJF219 Brushless Excitation Synchronous Generator
CRRC CDJF219 Traction Motor is a synchronous generator that employs an AC exciter and a rotating rectifier to supply excitation energy to the magnetic field of a coaxial generator. The rated power can reach 620 kW with a 336 amp rated current, and the rated voltage can reach up to 1170 V.CRRC CDJF219 traction motor’s rated speed is 1800 rpm, and with the separately excited mode. These parameters are adapted to the long-term or staged operation requirements of different working conditions under actual operation requirements. The overall weight of CRRC CDJF219 traction motor is about 2100 kg, which reflects the structural strength and stability of the equipment and is suitable for installation and operation in traction scenarios. It is equipped with a built-in cooling fan, and an additional cooling blower is not a necessity for the alternator.CRRC CDJF219 traction motor is capable of 110% overload operation at an altitude of some 1000 meters.We offer comprehensive life-cycle support for the motor, covering equipment supply, on-site installation and commissioning, maintenance training, spare parts provision, and ongoing technical troubleshooting services.
Advantages of CRRC CDJF219 Brushless Excitation Synchronous Generator
With a 620 kW rated power and 1170 V rated voltage, it delivers large-capacity, continuous power supply to meet the high-load demands of heavy-duty equipment (e.g., DMUs, industrial drive systems), ensuring stable operation under peak loads.
The brushless excitation design eliminates wearable brush components, reducing maintenance needs, lowering fault rates, and extending the generator’s service life—ideal for long-term continuous operation scenarios.
Its robust casing and heat-dissipating grid structure ensure efficient heat dissipation during high-power operation, while the 2100 kg heavy-duty build enhances stability and vibration resistance in harsh industrial environments.
As a synchronous generator, it maintains high power factor and conversion efficiency (matching industrial-grade performance standards), minimizing energy loss and reducing operational costs for equipment operators.
Designed to integrate with mainstream heavy-duty equipment (e.g., large DMUs, industrial power systems), it supports standardized connection interfaces and adapts to diverse power system configurations, enhancing its applicability across multiple scenarios.
