Advanced Enclosure & Cooling Systems
The YJS series is defined by its totally enclosed, fan-cooled design, offering two primary cooling configurations to suit different operational needs:
- IC411 / IP55 (Standard): Features an external shaft-mounted fan that utilizes surrounding air for cooling. The IP55 rating provides reliable protection against dust ingress and water jets from any direction.
- IC416 / IP66 (Optional): Designed for low-speed applications or variable frequency drive (VFD) operations, this configuration uses an independent motor to drive the cooling fan. The upgraded IP66 enclosure is completely dust-tight and can withstand powerful water jets, making it ideal for harsh environments.
Packaging, Warranty & Logistics
To ensure safe transit, each motor is secured in standard seaworthy packaging, utilizing plywood or fumigated wooden crates suitable for long-distance sea or land transportation. Changli stands behind the quality of the YJS450-2-500KW with a comprehensive warranty: 12 months after commissioning or 18 months after delivery, whichever occurs first. Extended warranty options are also available upon request.
