Characteristics

Overview
The 1FK7 servo gear motors are preassembled as a complete unit and supplied with
a gearbox filled with oil. The range of types includes:
• Helical geared motors with 9 gearbox sizes
• Offset shaft geared motors with 5 gearbox sizes
• Bevel geared motors with 8 gearbox sizes, and
• Worm gear motors with 5 gearbox sizes
A wide range of mounting possibilities can be implemented with the numerous options.
The 1FK7 servo gear motors are designed for operation without external cooling and
the generated heat loss is dissipated through the motor surface. 1FK7 servo gear motors
can be combined with the SINAMICS S120 drive system to create a powerful system with
high functionality. Integrated encoder systems for speed and position can be selected
depending on the application just as for 1FK7 servomotors.
Benefits
1FK7 servo gear motors offer:
• Extremely compact design as a result of the direct mounting (because there is no
• Maintenance-free and lubricated for life (exception: worm gearbox)
• High efficiency
• Low torsional backlash
• Low running noise thanks to the low running noise due to the helical gearing
• High endurance gearing (exception, worm gearbox)
• Suitable for cyclic operation with alternating load and continuous operation
• Favorably-priced solution when compared to planetary geared motors
