YBBP132S2-2 Explosion-proof VVVF 3 Phase 7.5 Kw Induction Motor

Brief Introduction

Produced by Xi'an Taifu SIMO Motor Co., Ltd., the YBBP series stands for flameproof variable-frequency three-phase induction motors strictly designed and manufactured in line with JB/T11201.1 national industrial standards and international explosion-proof certification criteria, becoming a core driving solution for hazardous working sites with flammable and explosive gas mixtures. Among the full-size product lineup, the 7.5 kw induction motor represented by model YBBP132S2-2 is one of the most well-received benchmark specifications, widely stocked and selected by global clients for medium-load variable-speed industrial transmission, and this mature motor has set a solid reference standard for the whole YBBP product range in structural design and performance calibration.

This standard 7.5 kw induction motor is rated at 380V, 50Hz power supply, featuring an excellent energy efficiency of 88.1% and a power factor of 0.89 under rated working condition. Its most prominent highlight lies in ultra-wide variable speed adjustment capacity, with adjustable rotational speed ranging from 300r/min up to 6000r/min; the corresponding working frequency spans 5Hz to 100Hz, enabling flexible speed matching for different production technological requirements without extra mechanical speed reduction equipment. Stator winding adopts delta connection mode, equipped with Class F high-temperature resistant insulation that can endure up to 155℃, greatly enhancing winding anti-overload and anti-aging performance during long-term variable-frequency running, effectively avoiding insulation breakdown caused by frequent frequency conversion impacts.

For explosion-proof and environmental adaptability advantages, all YBBP motors including the versatile induction motor 7.5 kw obtain official Ex d IIBT4 Gb flameproof certification and complete explosion-proof qualification filing, which allows safe operation in sites containing Class IIB explosive gases like ethylene. The overall enclosure reaches IP55 protection grade, perfectly blocking dust intrusion and preventing splashing water damage to internal components. With specially selected 6208-2Z/C3 clearance bearings installed at both drive end and non-drive end, the motor effectively offsets thermal expansion during high-speed rotation, lowering mechanical friction loss and extending whole-unit service life. Designed for harsh ambient conditions, it can steadily operate within an extreme temperature scope from -41℃ to 40℃ and runs normally at an altitude below 1000 meters, adapting to frigid outdoor workshops and open-air mining environments. The S1 continuous-duty design supports non-stop long-hour running for uninterrupted production lines, reducing unexpected shutdown losses for end factories.

In practical industrial deployment, the robust structure and reliable explosion-proof property make the YBBP series, especially the popular 7.5 kw induction motor, extensively applied across petroleum refining, fine chemical engineering, coal mining, natural gas transportation and pharmaceutical production industries. It serves as core drive for explosion-proof fans, chemical process pumps, material conveyors and mixing machinery in dangerous areas. Compared with ordinary fixed-speed explosion-proof motors, this variable-frequency model cuts idle power consumption remarkably via adjustable rotating speed, helping customers slash long-term electricity costs. All finished motors undergo strict explosion-proof inspection, no-load running test and variable-frequency aging detection before factory delivery, securing consistent operational stability and low failure rate, so the SIMO YBBP range has gained steady market reputation and continuous repeat orders from domestic and overseas hazardous-process equipment manufacturers.
