The INDRAMAT MAC093B-0-OS-2-C/130-A-0/S005 is a high-performance AC servo motor designed for use with Indramat (Bosch Rexroth) drive systems, such as the DSC, TDM, or KDS series. This motor is part of the MAC series, known for its permanent magnet brushless design, which provides high torque-to-inertia ratios and exceptional reliability in demanding industrial environments. The “S005” designation indicates a specialized configuration or modification tailored for specific high-precision machinery.
Key Product Specifications

Application Fields
This motor is primarily used in CNC machinery and automated production lines:
- Machine Tools: Driving feed axes for milling, drilling, and grinding machines.
- Packaging Industry: Providing synchronized motion for labeling and wrapping equipment.
- Robotics: Powering articulated arms or gantry systems requiring precise positioning.
- Printing Presses: Maintaining tension and registration control in high-speed printing.
Usage Instructions
- Mounting: Ensure the mounting flange is clean and properly aligned with the gearbox or drive shaft. The 130 mm centering diameter must fit precisely into the housing to prevent vibration and premature bearing wear.
- Electrical Connection: Connect the power and feedback cables (Tacho/Encoder) using the heavy-duty circular connectors. Ensure the connectors are fully tightened to maintain the IP65 seal.
- Cooling: While naturally cooled, the motor should be installed in an area with adequate airflow. Excessive paint or dust buildup on the motor housing can lead to overheating.
- Commissioning: Use the Indramat drive software to verify the motor parameters. The “MAC093B” profile must be correctly selected in the drive configuration to ensure the current limits and velocity gains are optimized.
Q&A – Frequently Asked Questions
Q: Can this motor be repaired if the feedback system fails? A: Yes, the feedback units in Indramat MAC motors can often be repaired or replaced by specialized technicians; however, recalibration of the commutation point is required after any internal service.
Q: What does the “S005” suffix represent? A: S-series suffixes denote “Special” versions. These usually involve non-standard shaft dimensions, specialized connectors, or unique winding characteristics requested by the original equipment manufacturer (OEM).
Q: Is this motor compatible with modern Bosch Rexroth IndraDrive systems? A: While primarily used with legacy TDM/KDS drives, these motors can sometimes be integrated with newer drives using specific interface modules or analog-to-digital feedback converters.
Product News: Maintaining Precision in Legacy Systems
The INDRAMAT MAC093B series continues to be a cornerstone of the global manufacturing infrastructure. Despite the brand transition to Bosch Rexroth, these motors are highly sought after for maintaining legacy CNC machines that remain mechanically sound. Recent industrial trends show a rise in “Precision Overhauls,” where motors like the MAC093B-0-OS-2-C/130-A-0/S005 are refurbished with modern bearing materials and high-temp insulation to extend their service life another 10–15 years, offering a sustainable alternative to complete machine replacement.
