Adding precision and safety to your system with explosion-proof servomotors; ATEX-compliant motors can be used in environments with explosive air/gas or air/dust mixtures according to Category 3.
Implement Sew Eurodrive’s servo drive technology in potentially explosive areas! Precision, dynamics and performance in a particularly compact design. Potentially explosive environments are no problem with these servomotors.
Choose the right ATEX-compliant servomotor from a range of 6 sizes, CMP.. 40 to 100. Torque range from 0.5 Nm up to 47 Nm standstill torque. Safe design and additional protective measures meet requirements according to EU Directive 94/9/EC (ATEX), or as of April 20, 2016 of the EU Directive 2014/34/EU (ATEX). They are also available with different protection types depending on the atmosphere, i.e. gas or dust.
In terms of their safety requirements, the servomotors comply with equipment group II. In simple terms: You can use these Category 3 explosion-proof motors in Gas zone 2 or Dust zone 22.
Compliant with Directive 94/9/EC (ATEX), or as of April 20, 2016 of the EU Directive 2014/34/EU (ATEX), equipment group II, equipment category 3
Category II 3GD, for use in zones 2 / 22
Category II 3D, for use in zone 22
also available with brake and Hiperface® encoder (with electronic nameplate) in Category 3D
Protection Types and IP Degrees of Protection
Dustatmosphere: Protection type “t”
means: Unit protection against dust explosion through enclosures according to EN 60079-0 and -31
Gasatmosphere: Protection type “nA”
means: Protection according to EN 60079-0 and -15
through non-sparking constructive measures and design requirements as for protection type “e”; the difference being that only uninterrupted operation (no error) is considered.
Dustatmosphere: Degree of protection IP65
means: dust-tight housing according to EN 60079-31
dust is unable to enter the motor thanks to its housing design
permanent monitoring of the surface temperature, so as to exclude it as an ignition source
