Product Overview
The Shangli YBX5 series is an ultra-premium-efficiency, squirrel-cage three-phase induction motor for explosive-gas environments. It is a totally enclosed, fan-cooled flameproof motor developed in-house by Shangli.
The catalog specifies Grade 1 energy efficiency under GB 18613-2020, the highest grade of the Chinese standard (IE5 level). The series covers frame sizes 80 to 355 and outputs from 0.18 to 315 kW in 2-, 4-, 6- and 8-pole versions, with low vibration and noise.
Explosion protection meets GB 3836.2 (equipment protection by flameproof enclosures "d") for Zone 1 and Zone 2 explosive gas atmospheres. The catalog lists petroleum, chemical, coal mining, mining, ports, power plants and general engineering as application sectors, driving fans, compressors, pumps, crushers, hoists, centrifuges, machine tools and conveyors.
Key Features
- Highest Chinese efficiency grade: Grade 1 under GB 18613-2020 (IE5 level), with efficiency data published for every model.
- Flameproof configurations: Ex d I Mb and Ex d IIB T4 Gb, with Ex d IIC T4 Gb available. The required configuration must be specified when ordering.
- Totally enclosed, fan-cooled construction: IC411 cooling with a shaft-driven external fan.
- Environmental options: Indoor and outdoor anti-corrosion, humid-tropical and high-altitude versions are listed in the catalog.
- Same frame sizes as YBX4 and YBX3: Frame designations follow the same 80–355 range, which simplifies upgrading an existing flameproof motor to a higher efficiency grade. Confirm the dimensional drawing for the selected model.

Specifications describe the series range. Not every combination of output, voltage, frequency, mounting arrangement and protection marking is necessarily available. Confirm the final selection against the quoted datasheet, nameplate and applicable certificate.
Power Range by Pole Configuration
| Poles | Catalog Output Range | Synchronous Speed at 50 Hz |
|---|---|---|
| 2 | 0.75–315 kW | 3,000 rpm |
| 4 | 0.55–315 kW | 1,500 rpm |
| 6 | 0.37–250 kW | 1,000 rpm |
| 8 | 0.18–200 kW | 750 rpm |
Actual rated shaft speed is lower than synchronous speed and varies by model.
Flameproof Protection
The YBX5 catalog lists Ex d I Mb and Ex d IIB T4 Gb, with Ex d IIC T4 Gb available. In the marking Ex d IIB T4 Gb, "d" is the flameproof type of protection, "IIB" the equipment group, "T4" the temperature class and "Gb" the equipment protection level.
These are alternative configurations, not combined approvals for every motor. Specify the required gas group, temperature class, equipment protection level and hazardous-area classification with your enquiry. The current certificate and nameplate determine the approved marking and conditions of use. Where ATEX, IECEx or another destination-market approval is required, state it before quotation.
