ATEX IIB

Product catalog summary

Surface Protection: The standard painting process for bearings uses an epoxy-vinyl/polyamidic paint with a minimum thickness of 50 micrometers. An optional special painting process with polyacrylic paint increases the thickness to at least 200 micrometers. The finishing paint is RAL 5010, with other colors available upon request.

Thermal Protection: PT100 sensors and other protection combinations are available through Marelli Motori S.p.A.

Bearings: Various bearing types are used in standard configurations, with options for high load applications. Specific types are listed for different frame sizes.

Terminal Box and Cable Entry: The terminal box is located on top of the motor and can be rotated by 90°. It has 6 terminals and various cable entrance hole sizes depending on the frame size.

Protection Types: Protection types for gas and dust environments include Ex d, Ex e, and Ex tD A21 IP65, ensuring no internal explosions or sparks occur, and surface temperatures remain below ignition points.

Standards and Certifications: Motors comply with several IEC and EN standards and are approved by SABS and Gost R, suitable for use in potentially explosive atmospheres as per ATEX directives.

Equipment and Area Classifications: Motors are classified by equipment category and zone, with specific categories for gas and dust environments. Zone 0/20 prohibits the use of electric motors.

Materials: Materials specified include cast iron and steel for frame endshields and fan cowls.

Options and Customizations: Additional options and customizations are available, including frequency converter supply and other motor configurations.

Specifications: Detailed specifications for electric motors focus on frame sizes from 160 to 315. Detailed data for 440V/60Hz motors is available upon request, with higher output available for Temperature Class T3 and/or Maximum Surface Temperature T150°C. Motors are not multivoltage, and output values at 440V/60Hz refer to motors with dedicated winding.

Protection and Standards: Motors are designed with various protection types, including Ex d, Ex de, and Ex tD A21 IP65, suitable for different hazardous environments. Compliance with ATEX standards and other international standards like IEC and EN is outlined, along with equipment and area classifications detailing zones and categories for motor suitability.

Performance and Efficiency: Performance metrics such as rated output, speed, efficiency, power factor, and torque are provided for different motor types and frame sizes. Tables include detailed performance data at rated voltage and output, highlighting starting current, starting torque, and breakdown torque.

Construction and Materials: Construction materials include cast iron and steel for frame endshields and fan cowls. Surface protection options include standard and special painting processes.

Additional Features: Options for thermal protection, drainage holes, and terminal box configurations are discussed. PT100 and PTC sensors for thermal protection and optional anticondensation heaters are mentioned.

Certifications and Compliance: Motors are certified under various ATEX certificates and comply with European directives related to equipment used in potentially explosive atmospheres, electromagnetic compatibility, low voltage, and machinery safety.
