YJTKK355-2WF1 VVVF Three-phase Asynchronous 3000 Rpm AC Electric Motor 280KW

Brief Introduction

The YJTKK series VVVF three-phase asynchronous 3000 rpm ac electric motor from Xi'an SIMO Motor is a premium solution engineered for industrial variable speed applications, blending high efficiency, robust performance, and reliable operation to meet the demands of modern energy-conscious industries.

At the core of its design is top-tier energy efficiency, with models like the YJTKK355-2WF1 3000 rpm ac electric motor delivering an efficiency rating of up to 92.1%. This translates to significant operational cost savings over the motor's lifecycle, making it ideal for continuous-duty scenarios where energy consumption is a key concern. The motor is built for variable frequency drive compatibility, supporting a wide frequency range (0–50Hz, expandable to 5–50Hz for variable speed control), enabling precise speed regulation to match diverse load requirements in pumps, fans, compressors, and processing machinery.

Durability and reliability are hallmarks of the YJTKK series. With an IP54 protection rating, the motor safeguards against dust ingress and water splashes, ensuring stable performance in harsh industrial environments. Its IC666 cooling system (air-water cooling) efficiently dissipates heat, preventing overheating even under heavy loads, while the S1 continuous duty rating guarantees uninterrupted operation for extended periods. The use of 6319/C3 bearings minimizes friction and vibration, reducing maintenance needs and extending service life.

Safety and compliance are prioritized in every unit. This YJTKK 3000 rpm ac electric motor features clear operational guidelines for startup, including requirements for cooling water supply and bearing lubrication, while CE certification ensures adherence to international safety standards. Whether deployed in mining, chemical processing, or manufacturing, the YJTKK series offers consistent power output, low noise operation, and compatibility with various coupling systems for seamless integration with driven machinery.

Backed by Xi'an SIMO Motor's decades of expertise in electric motor manufacturing, the YJTKK series combines advanced engineering with rigorous quality control, making it the trusted choice for industrial users seeking high-efficiency, low-maintenance variable speed motors.
