Title:

YBBP Variable Frequency Explosion Proof AC Motor

Brief Introduction

AIMIN's YBBP series-exemplified by the YBBP280S-2GW-stands as a specialized solution for hazardous industrial environments, merging flameproof safety, variable-frequency flexibility, and robust performance. Designed by AIMIN ELECTRICS, this line of flameproof variable-frequency three-phase asynchronous ex d motor is purpose-built to power critical heavy-duty equipment: large centrifugal pumps, high-capacity ventilation fans, heavy-duty conveyor systems, and industrial compressors-applications where reliability in explosive atmospheres is non-negotiable.

The YBBP280S-2GW, a flagship model, delivers 75kW of power at 380V, with a standout 93.8% efficiency and 0.89 power factor that cuts energy costs even during continuous S1 duty. Its variable-frequency capability (5–50Hz) enables speed adjustment from 300 to 3600r/min, adapting seamlessly to fluctuating load demands in sectors like petrochemicals, mining, and chemical processing.

Certified with Exd [ib] II CT4 (CNEx23.5850X), it meets strict explosion-proof standards for flammable gas/dust environments. Enhanced with IP55 protection and 155(F)-class insulation, paired with durable 6314/C3 bearings (both drive and non-drive ends), this ex d motor withstands harsh conditions-including 37°C ambient temperatures and 1300m altitudes-while minimizing maintenance needs.

Weighing 593kg (IM B3 mounting), the YBBP series ex d motor balances stability and adaptability, making it the trusted choice for industrial systems that require both high performance and safety compliance. Backed by AIMIN's engineering expertise, this series redefines reliability for heavy-duty, hazardous-location operations.
