SIMOTICS S‑1FK2 and S-1FT2 servo planetary geared motors with coaxial gearboxes NRB, NRK, NLC and SIMOTICS S-1FT2 servo planetary geared motors with the NRBW, NRKW, NLCW angular gearboxes are highly dynamic, compact and economical drive units. The combinations, each composed of a servomotor with a high-performance coaxial or right-angle planetary gearbox, are suitable for a wide range of applications in an industrial environment.
These planetary geared motors are specified and delivered completely as a unit. All outstanding performance data are matched to the motor-gearbox combination.
Motors
High Dynamic
Wherever small masses have to be moved with maximum dynamics and precision, the 1FK2 and 1FT2 High Dynamic servomotors with low inertia really come into their own.
The lightweight and low-friction gearboxes in conjunction with inertia-optimized clamping systems allow the highest cycle rates in the application.
Compact
If larger loads need to be moved with precision and dynamically, a motor version with higher inertia is unavoidable for controllable operations. The 1FK2 and 1FT2 Compact servomotors with medium inertia and planetary gearboxes with higher transmission ratios enable even difficult inertia conditions to be mastered in terms of the control technology.
Planetary gearboxes
The three planetary gearboxes NRB(W), NRK(W), and NLC(W) can be mounted in all spatial positions without restriction and are maintenance-free thanks to their lifetime lubrication.
Coaxial gearboxes
NRB
NRB is the lightest gearbox with the highest power density. Thanks to its low friction bearing design it is suitable for high speeds and only generates a slight amount of heat.
Application areas:
- Packaging
- Food industry
- Pharmaceutical and medical systems
- Auxiliary axes in machine tools
NRK
The NRK series gearbox is suitable for higher radial and axial forces due to the large output bearing. This gearbox is also suitable for higher speeds thanks to low internal friction.
Application areas:
- Automation and mounting technology
- Packaging
- Auxiliary axes in machine tools
NLC
Thanks to the preloaded tapered roller bearing, the NLC gearbox has a high degree of stiffness and is perfectly suited for high radial and axial loads. The IP65 cover provides protection against dust and water.
Application areas:
- Automation and mounting technology
- Packaging
- Food industry
- Printing industry
- Auxiliary axes in machine tools
Angular gearboxes
An initial bevel gear stage makes the planetary gearboxes NRB, NRK and NLC also available as angular gearboxes NRBW, NRKW and NLCW.
The right-angle versions are the right choice in confined spaces.
Due to the additional angular stage, the losses in the angular gearboxes are slightly higher and the rated specifications are reduced in comparison to the comparable coaxial version.

Possible motor-gearbox combinations
Notes:
The geared motor can only be delivered as a unit – motor plus gearbox – (no individual gearboxes).
Not all combinations are possible.
For shaft design with feather key, the gearbox data only applies for pulsating loads. With alternating load / reversal of direction of rotation, limitation of the torque as a function of the number of load cycles is required (see Configuration Manual).

Shaft extension options
The output shaft of the planetary gearbox can be ordered as a plain shaft for a friction-locked connection or optionally with a feather key for positive transmission.
A friction-locked connection free of backlash (plain shaft) is recommended for dynamic loads, particularly during reversals in operation.
For pulsating loads without reversals, a positive feather key connection is also suitable as an alternative.
Limitation of output torques for gearbox shaft with feather key
It must be ensured that the following torques are not exceeded at the output shaft for gearboxes with feather key and changing application loads. Regardless of this, other limitations such as maximum torque M2max, G or the rated torque M2N,G of the gearbox components are maintained.

G– Efficiency of the gearbox components under full load
The exact values for the efficiency are, to some extent, dependent on the frame size of the mounted motor and can be found in the data sheet resulting from the configuration in the Siemens Product Configurator.
In the partial load range, especially when the gearbox is cold, the efficiency of the gearbox is always lower than at operating speed.
The gear losses are already taken into account in the characteristic curves and in the following characteristic data of the geared motor or its components: M2,0, M2,max, M0,M, Mmax,M
A reduction of this characteristic curve and the characteristics on efficiency is not necessary.

Permissible shaft loading capacity
The limit values shown for the bearing load refer to equivalent forces to be determined mathematically, whose effect is equivalent to the forces occurring in the load profile.
They only apply to radial and axial loads. Axial forces up to maximum FA = 0.24 × FR are permissible in case of superimposition.
They apply to the output speed of 100 r/min and in case of radial force for a force application point in the center of the shaft or for centrally applied axial force. For other speeds or force application points, the permissible radial forces must be obtained from the radial force diagrams of the Configuration Manual.

G– Efficiency of the gearbox components under full load
The exact values for the efficiency are, to some extent, dependent on the frame size of the mounted motor and can be found in the data sheet resulting from the configuration in the Siemens Product Configurator.
In the partial load range, especially when the gearbox is cold, the efficiency of the gearbox is always lower than at operating speed.
The gear losses are already taken into account in the characteristic curves and in the following characteristic data of the geared motor or its components: M2,0, M2,max, M0,M, Mmax,M
A reduction of this characteristic curve and the characteristics on efficiency is not necessary.

The limit values shown for the bearing load refer to equivalent forces to be determined mathematically, whose effect is equivalent to the forces occurring in the load profile.
They only apply to radial and axial loads. Axial forces up to maximum FA = 0.24 × FR are permissible in case of superimposition.
They apply to the output speed of 100 r/min and in case of radial force for a force application point in the center of the shaft or for centrally applied axial force. For other speeds or force application points, the permissible radial forces must be obtained from the radial force diagrams of the Configuration Manual.

G– Efficiency of the gearbox components under full load
The exact values for the efficiency are, to some extent, dependent on the frame size of the mounted motor and can be found in the data sheet resulting from the configuration in the Siemens Product Configurator.
In the partial load range, especially when the gearbox is cold, the efficiency of the gearbox is always lower than at operating speed.
The gear losses are already taken into account in the characteristic curves and in the following characteristic data of the geared motor or its components: M2,0, M2,max, M0,M, Mmax,M
A reduction of this characteristic curve and the characteristics on efficiency is not necessary.

G– Efficiency of the gearbox components under full load
The exact values for the efficiency are, to some extent, dependent on the frame size of the mounted motor and can be found in the data sheet resulting from the configuration in the Siemens Product Configurator.
In the partial load range, especially when the gearbox is cold, the efficiency of the gearbox is always lower than at operating speed.
The gear losses are already taken into account in the characteristic curves and in the following characteristic data of the geared motor or its components: M2,0, M2,max, M0,M, Mmax,M
A reduction of this characteristic curve and the characteristics on efficiency is not necessary.

Permissible shaft loading capacity
The limit values shown for the bearing load refer to equivalent forces to be determined mathematically, whose effect is equivalent to the forces occurring in the load profile.
They only apply to radial and axial loads. Axial forces up to maximum FA = 0.24 × FR are permissible in case of superimposition.
They apply to the output speed of 100 r/min and in case of radial force for a force application point in the center of the shaft or for centrally applied axial force. For other speeds or force application points, the permissible radial forces must be obtained from the radial force diagrams of the Configuration Manual.

G– Efficiency of the gearbox components under full load
The exact values for the efficiency are, to some extent, dependent on the frame size of the mounted motor and can be found in the data sheet resulting from the configuration in the Siemens Product Configurator.
In the partial load range, especially when the gearbox is cold, the efficiency of the gearbox is always lower than at operating speed.
The gear losses are already taken into account in the characteristic curves and in the following characteristic data of the geared motor or its components: M2,0, M2,max, M0,M, Mmax,M
A reduction of this characteristic curve and the characteristics on efficiency is not necessary.

Permissible shaft loading capacity
The limit values shown for the bearing load refer to equivalent forces to be determined mathematically, whose effect is equivalent to the forces occurring in the load profile.
They only apply to radial and axial loads. Axial forces up to maximum FA = 0.24 × FR are permissible in case of superimposition.
They apply to the output speed of 100 r/min and in case of radial force for a force application point in the center of the shaft or for centrally applied axial force. For other speeds or force application points, the permissible radial forces must be obtained from the radial force diagrams of the Configuration Manual.

M
2N, G – Rated torque for gearbox components
An endurance strength calculation becomes necessary if this torque is exceeded (see Configuration Manual). For the feather key version, the gearbox nominal torque is only permissible as a pulsating load or a reduction must be carried out depending on the number of load changes (see Components and Options).

G– Efficiency of the gearbox components under full load
The exact values for the efficiency are, to some extent, dependent on the frame size of the mounted motor and can be found in the data sheet resulting from the configuration in the Siemens Product Configurator.
In the partial load range, especially when the gearbox is cold, the efficiency of the gearbox is always lower than at operating speed.
The gear losses are already taken into account in the characteristic curves and in the following characteristic data of the geared motor or its components: M2,0, M2,max, M0,M, Mmax,M
A reduction of this characteristic curve and the characteristics on efficiency is not necessary.

Permissible shaft loading capacity
The limit values shown for the bearing load refer to equivalent forces to be determined mathematically, whose effect is equivalent to the forces occurring in the load profile.
They only apply to radial and axial loads. Axial forces up to maximum FA = 0.4 × FR are permissible in case of superimposition.
They apply to the output speed of 100 r/min and in case of radial force for a force application point in the center of the shaft or for centrally applied axial force. For other speeds or force application points, the permissible radial forces must be obtained from the radial force diagrams of the Configuration Manual.
