YFB180L -4 Three Phase Asynchronous Dust Explosion Proof Induction Motor 380V

Brief Introduction

Developed and manufactured by Xi'an SIMO Motor Co., Ltd., the YFB series is a high-performance, three-phase asynchronous explosion proof induction motor specifically crafted to address the safety and operational needs of hazardous industrial environments where combustible dust is present. As a professional solution for high-risk sectors, this series combines advanced engineering, strict safety compliance, and long-term reliability, making it an indispensable choice for industries that prioritize personnel safety and production continuity.

Taking the YFB180L-4 explosion proof induction motor as the representative, this motor boasts excellent technical specifications that ensure optimal performance. It features a rated power of 22 kW, a synchronous speed of 1480 r/min, and is compatible with a 380 V, 50 Hz three-phase power supply, with a rated current of 41.2 A. With an efficiency of 95.5% and a power factor of 0.88, it achieves remarkable energy savings, helping enterprises reduce long-term operational costs while maintaining stable output. Equipped with Class 155(F) insulation, it can withstand high operating temperatures, effectively preventing overheating and extending the motor's service life.

Safety is the core advantage of the YFB series. It has obtained official explosion-proof certification (CNEX252677X) and complies with Ex tD A21 IP65 T135℃ Db standards, which can reliably prevent ignition of combustible dust clouds, making it suitable for safe operation in Zone 21 hazardous areas. The YFB180L explosion proof induction motor adopts a robust cast iron frame, which enhances its mechanical strength and vibration resistance, while the 6311/C3 bearings on both drive and non-drive ends ensure smooth operation and reduce maintenance needs. Rated for S1 continuous duty, it can operate uninterruptedly under harsh working conditions, minimizing downtime.

With strong adaptability, the YFB series can work stably in ambient temperatures up to 40°C and altitudes up to 1000 m, adapting to various regional and environmental conditions. Its 225 kg weight and IM B3 mounting mode offer flexible installation options, suitable for matching with conveyors, crushers, mixers, fans and other industrial equipment. Backed by SIMO's professional manufacturing experience and comprehensive after-sales service, including a 24-hour support hotline (4000291177), the YFB series provides users with full-cycle technical support and maintenance services, ensuring long-term stable operation and peace of mind.
