ExDe Motor - Flame-Proof & Increased Safety Motor Solutions

The power equipment used in plants that process explosive gases must be of containment strength and precise engineering. An exde motor combines Ex d (flame-proof) casings with Ex e (improved safety) connections to provide double protection for dangerous zones. Shaanxi Qihe Xicheng Electromechanical Equipment Co., Ltd. delivers enterprise-grade explosion-proof motors with protection ratings up to IP55, insulation class F, and operational stability across -20°C to +40°C ambient temperatures. Our motors find applications in the petrochemical, mining and pharmaceutical industries where safety is critical. Backed by over 20 years of experience in power solutions and collaborations with 30+ worldwide manufacturers like ABB and Siemens.

ExDe Motor Supplier & Manufacturer

We have strategic partnerships with industry-leading brands such as ABB, Siemens, Wolong, NEC and XEMC. This network allows us to obtain certified components to the ATEX, IECEx and CCC requirements. Our supply chain architecture is built to assure quality at every step, from raw material selection to final assembly. We monitor production statistics and maintain traceability for compliance with regulations with factory management systems built on SAP.

Pain points and solutions

The Problem: Traditional motors produce sparks in explosive atmospheres, which might lead to catastrophic failure.

Solution: Our flame-proof enclosures are designed to contain internal explosions and prohibit the spread of ignition to the surrounding gases.

Challenge: Recurrent motor failures in chemical corrosive conditions.

Solution: Hot spots are prevented by higher safety terminals with increased creepage distance and appropriate insulating materials.

Challenge: Unpredictable lead times might derail project plans.

We fine-tune delivery cycles with inventory management and flexible logistics partnerships, enabling sea, land and air freight alternatives.

Technical Specifications

​​​​​​​

Technical Advantages

Dual Protection Design

The Ex d housing contains any internal explosion, while Ex e components prevent arc formation through precision manufacturing tolerances below 0.01mm.

Inverter-Ready Construction

Special enameled wire resists harmonic distortion. Independent IC416 cooling fans maintain airflow regardless of variable frequency drive (VFD) speed adjustments.

Thermal Management

Built-in PT100 sensors monitor winding temperatures in real-time, triggering automatic shutdowns before insulation degradation occurs.

Reinforced Insulation

F-class materials suppress corona discharge under VFD operation, extending service life by 40% compared to standard motors.

Production Process

Design Validation: CAD modelling confirms explosion-proof joint surface flame route requirements

Material Selection: Only approved steel alloys and flame retardant polymers are used in manufacture

Precision Machining: CNC machinery can hold accuracy to within 0.05mm on flange flatness

Assembly Clean-room conditions avoid contamination during winding and terminal installation

Testing confirmed Performance: hydrostatic pressure testing, voltage surge simulation, and temperature cycling

Certification: Certified by third-party inspections prior to shipment for conformance with EN 60079 requirements

Industry Applications

Petrochemical: Volatile Hydrocarbon Refinery Zone 1 Hazardous Area Pumping Systems

Mining: Coal conveyor systems with variable methane gas concentrations

Pharmaceutical: Classification of solvent recovery equipment in clean room conditions

Food Processing Grain handling equipment exposed to flammable dust

Mixers working around solvent vapour clouds, Manufacture of Paints

Our exde motor units are used to drive centrifuges, screw compressors and ventilation fans where continuity of operation is dependent on fail-safe design.

FAQ

Q：What does ExDe mean in motor terminology?

A：ExDe combines two protection methods: Ex d (flame-proof enclosure containing explosions) and Ex e (increased safety terminals preventing ignition sources). This hybrid design suits applications requiring both robustness and precision.

Q：Can the products operate with variable frequency drives?

A：Yes. Models like YBBP feature inverter-resistant insulation and independent cooling systems. Always install output reactors for cable runs exceeding 50 meters and avoid prolonged operation below 5Hz.

Q：What maintenance intervals apply?

A：Inspect explosion-proof joint surfaces quarterly. Check bearing lubrication every 2,000 operating hours. Verify independent fan operation monthly when using VFDs.

Q：How do I select between 50Hz and 60Hz versions?

A：Match motor frequency to your power supply. We customize 60Hz units with adjusted winding turns and core lamination thickness to maintain torque characteristics.
