Servo Repair International, Inc. repairs and replaces many of the brands of servo motors, including Siemens.

Siemens is a German engineering corporation and is the largest such company in Europe. Siemens’ industrial automation division is the most profitable of the various activities of the company.

Siemens offers a range of servo motor products for use in control application and among these are numerous brushless servo motors. Servo Repair International can apply our knowledge, skills, and replacement capabilities to support Siemens end users and keep their motors and systems operational.

Machine designers must match the appropriate servo motors with the needs of the application and the various series of Siemens AC servo motors with a range of unique characteristics provide plenty of options to fit those needs. Below are descriptions of some of the series Siemens offers and that Servo Repair International service.

 

Siemens Motors


 

If your motor is not represented below, please call us as our capabilities are always expanding!

If your motor is not a Siemens, refer to our AC Servo Motor list to view a list of manufacturers we can service.

1FT5 Series

Please click on the 1FT5 Series link above to view our 1FT5 servicing and replacement capabilities page.

1FT6 Series

The 1FT6 series servo motors are available at rated speeds between 3000 and 6000 RPM and at stall torques between 0.4 and 140 Nm, slightly narrower ranges than their 1FT5 counterparts. The servo motors are designed for operation with sinusoidal current so squarewave style tach halls are not offered. Externally mounted encoders are also not offered with this series. The choice between forced ventilation or natural cooling packages is available with this series.

1FT7 Series

The 1FT7 series servo motors are available at rated speeds between 3000 and 6000 RPM and at stall torques between 1.4 and 250 Nm, slightly widerer ranges than their 1FT6 counterparts. The servo motors are designed for operation with sinusoidal current so squarewave style tach halls are not offered. Externally mounted encoders are also not offered with this series. The choice between forced ventilation or natural cooling packages is available with this series.

Siemens Drive Cliq

Drive Cliq motors are slowly becoming the majority of motors in the Siemens line up. We are able to run motors with Drive Cliq and work on the encoder during all Siemens evaluations. As always motors are run on their appropriate drive before shipping as a part of our final inspection.

1FK6 Series

The 1FK6 series servo motors are available at rated speeds between 3000 and 6000 RPM and at stall torques between 1.1 and 36 Nm. The servo motors are designed for operation with sinusoidal current so squarewave style tach halls are not offered. Externally mounted encoders are also not offered with this series. The 1FK6 series’ flanges and shafts are compatible with those of the 1FT6 series. The choice between forced ventilation or natural cooling packages is available with this series.

1FK7 Series

The 1FK7 series servo motors are available at rated speeds between 3000 and 6000 RPM and at stall torques between 0.6 and 37 Nm. The 1FK7 series are physically smaller while delivering equal power to their 1FK6 counterparts. The servo motors are designed for operation with sinusoidal current so squarewave style tach halls are not offered. Externally mounted encoders are also not offered with this series. The 1FK7 series’ flanges, shafts, and connectors are compatible with those of the 1FK6 series. The choice between forced ventilation or natural cooling packages is available with this series.

 

Free Motor Evaluation and Quote


 
 

Servo Repair International offers free evaluation of servo motors. Our evaluations entail a full disassembly of the unit and complete testing of all its components. The evaluation is free as a result of our four decades of engineering design, test and repair experience of servo systems. This knowledge enables us to effectively test and diagnose servo motors in an efficient time frame. In addition, by analyzing the type of failure, we may be able to identify the causative source and offer advice on preventing future failures.

 
 

Replacement Capabilities


 
 

In addition to repairing your Siemens motor, SRI in most cases can offer an exact “Refurbished / Rebuilt” replacement.

Refurbished / Rebuilt replacements are completely tested and come with a 1-year warranty. If you wish to pursue this option, give us a call at: 412-492-8116.
