1FS6 explosion-protected synchronous servomotors
1FS6 motors are permanent-magnet synchronous motors for use in Zone 1 hazardous areas.
They are designed in compliance with the EEx de IIC T3 type of protection, certified according to ATEX guidelines 94/9/EG, and also have CSA approval for Class 1, Zone 1, Temperature Class T3 (CAN/CSA-79-1-95 "Flameproof enclosure").
In addition to compliance with the ATEX guidelines, the motors also comply with the applicable standards and regulations for hazardous environments:
- IEC EN 60079-0
General Conditions for Electrical Equipment for Potentially Explosive Atmospheres
- IEC EN 60079-1
Standard referring to EEx d type of protection
- IEC EN 60079-7
Standard referring to EEx e type of protection
- IEC EN 60079-15
Standard referring to Ex nA type of protection
1FS6 motors can be combined with the SINAMICS S120 drive system to create a powerful, high-performance system. The integrated encoder systems for speed and position control can be selected depending on the application.
The motors are designed for operation without external cooling as the heat is dissipated through the motor surface.
