ZOOMRY
1. Product Overview
ZOOMRY Explosion Proof motors are three-phase asynchronous motors engineered for belt conveyor drive systems in hazardous environments — primarily underground coal mining where methane atmospheres may be present. The flameproof enclosure design (Ex d) is certified for mining applications, with additional hazardous-area classifications subject to specific certification and model availability. Available with power ratings from 2.2kW to 315kW across frame sizes H100 to H355.
Housing material depends on frame size and project specification. The motors are rated for continuous-duty (S1) conveyor drive applications with Class F insulation. Exact certification marking, voltage configuration, mounting arrangement, and enclosure protection must be confirmed against the hazardous area classification and local requirements before quotation.
2. Where Explosion Proof Motors Are Required
Belt conveyor systems operating in underground coal mines or facilities processing combustible dust require drive motors certified for the applicable hazardous area. Standard motors can generate sparks or surface temperatures that may ignite flammable atmospheres — creating unacceptable safety risks.
The explosion proof motor addresses this through flameproof enclosure design with appropriate temperature classification for the hazardous zone. Certification marking — such as Ex d I Mb for mining applications or group-specific gas classifications — must be confirmed against the specific motor model and certificate. Available certification and marking depend on the applicable hazardous area and are subject to the corresponding certificate documentation.
3. Key Features
Flameproof Enclosure Design — Ex d construction for hazardous mining environments. Certification marking varies by model and must be confirmed for the applicable hazardous area.
Efficiency Configurations — IE3 efficiency class configurations are available for selected models, subject to frame size and certification requirements. Confirm applicable efficiency classification at quotation.
IP55 Enclosure Protection — Standard protection against dust ingress and water jets from any direction. IP56, IP65, and IP66 options may be available for specific models.
Class F Insulation — Designed for continuous-duty applications with elevated temperature tolerance compared with lower insulation classes.
Reduced Routine Maintenance Requirements — Sealed bearing designs reduce lubrication frequency compared with open bearing arrangements, subject to the site maintenance plan and operating conditions.
