EX3M Flameproof Threephase Motor

Product catalog summary
Overview: The document provides comprehensive technical specifications and ordering information for the EX3M motor series by Fonteck Industries, designed for hazardous environments with explosive gases. It emphasizes the motor's flameproof features, construction materials, and typical applications.
Specifications: The EX3M motor is a three-phase asynchronous induction motor with a flameproof terminal box, constructed from cast iron and equipped with an over-heat protection sensor. It is suitable for use with compressors, fans, and pumps in hazardous locations, certified for gas groups IIA, IIB, or IIC, and temperature classes T4 to T1.
Certification: The motor is ATEX certified by DNV, with a certificate number DNV 14 ATEX 5038X. It is designed for environments with ambient temperatures ranging from -15°C to +40°C and has an ingress protection rating of IP55.
Technical Data: Available in frame sizes 63 to 280, the motor offers horizontal or vertical mounting options. It operates at rated voltages of 380 or 415 VAC and frequencies of 50 or 60 Hz, with an efficiency classified as IE2, a duty cycle of S1 (continuous), and insulation class F.
Performance Data: The document includes tables with performance metrics such as power output, efficiency, current, and sound pressure levels for various frame sizes and speeds (3000, 1500, 1000, and 750 r/min).
Cooling and Ventilation: Standard EX3M motors feature a radial flow fan for cooling, compliant with EN 60034-6 cooling method IC411. An optional external blower is available for applications requiring additional ventilation.
Mounting and Dimensions: Detailed dimensions for mounting the motor in various configurations are provided, including typical mounting IM B3 for frame sizes 63 to 355.
Ordering Information: The document includes an ordering table explaining the coding system for specifying motor types, covering product type, motor center height, frame length, stator length, number of poles, voltage rating, frequency, and mounting type. For example, the code EX3M-80-M1-4-380-A-B3 specifies a medium frame length motor with 4 poles, 380V, 50Hz, and B3 mounting.

EX3M Flameproof Threephase Motor-1

Three‐phase asynchronous induction motor Flameproof terminal box Terminal box top mounted and can be rotated by 4 x 90° Cast iron material Motor over‐heat protection sensor and module option Typical application: compressors, fans, pumps etc. for hazardous location EX3M motor is used in hazardous location with explosive gas of class IIA, IIB or IIC and temperature class of T4 to T1. They are totally enclosed fan cooled (TEFC) squirrel‐cage motors which have many remarkable features such as high‐efficiency, compact construction, low noise, lightweight, reliable and convenient maintenance and long service life etc. High strength materials and class F insulation assure the safety and reliability. The stator windings are wound with high‐strength polyester enameled round copper wire and treated with the progress of vacuum‐pressure impregnation (VPI) to make them as a whole, thus good electrical, mechanical performance, moisture resistance and thermal stability could be achieved. The rotors of motor are dynamically balanced to make them operate smoothly with small vibration and low noise. EX3M motor is ATEX certified. This product can typically be used as motor of compressors, fans and pumps etc. in hazardous location.
