Description
The INDRAMAT MAC112C-0-ED-2-C/130-B-0 is a high-performance, permanent magnet AC synchronous servo motor from Bosch Rexroth’s legacy Indramat MAC series. Designed for dynamic positioning, speed control, and torque-critical applications, it combines compact mechanical design with robust electrical performance—making it ideal for CNC machines, printing presses, robotic arms, and automated assembly lines.
Featuring a resolver-based feedback system, IP65 protection, and optimized thermal management, the MAC112C-0-ED-2-C/130-B-0 delivers smooth operation from near-zero to 3000 RPM while maintaining high efficiency and long service life—even in harsh industrial environments with dust, oil mist, or temperature fluctuations.
Application Scenarios
At a German automotive component supplier, a high-speed pick-and-place robot began experiencing axis jitter during rapid direction changes, causing misaligned insertions and scrap rates to spike. Root cause analysis revealed aging brushless motors with degraded feedback signals. The team replaced them with INDRAMAT MAC112C-0-ED-2-C/130-B-0 units, leveraging their low rotor inertia and high torque density. Within days, cycle time improved by 12%, and positional repeatability stabilized at ±0.02 mm—well within tolerance. Maintenance logs later showed zero motor-related faults over 14 months of 24/7 operation. This transformation underscores how the MAC112C-0-ED-2-C/130-B-0 solves critical pain points like mechanical resonance, thermal drift, and signal noise that plague older motion systems.
Note: The “130” in the model denotes the voltage constant (Ke), not supply voltage—the motor is driven by a compatible Indramat or IndraDrive amplifier providing regulated DC bus power.
Technical Principles and Innovative Values
Innovation Point 1: Optimized Electromagnetic Design for Low Cogging – The MAC112C-0-ED-2-C/130-B-0 uses skewed stator slots and precision-magnetized rotor segments to minimize torque ripple below 0.5%—enabling buttery-smooth motion at crawl speeds (<1 rpm), essential for glass handling or optical alignment tasks. Innovation Point 2: Thermal Resilience via Distributed Windings – Unlike concentrated-winding motors that suffer hot spots, this model employs distributed windings with Class H insulation (180°C rating), allowing sustained overload without derating—proven in continuous-duty extrusion lines. Innovation Point 3: Resolver-First Architecture for EMI Immunity – In high-noise environments (e.g., welding cells or plasma cutters), resolvers outperform incremental encoders. The MAC112C-0-ED-2-C/130-B-0’s analog resolver interface ensures reliable commutation even with cable lengths >50 m—eliminating position loss during electrical transients.
Innovation Point 4: Backward & Forward Compatibility – Despite being part of the legacy Indramat line, this motor integrates seamlessly with modern IndraDrive Cs/CsB amplifiers via parameter auto-recognition—protecting OEM investments during control system upgrades.
Application Cases and Industry Value
A U.S. medical device manufacturer retrofitted its catheter laser-cutting machines with INDRAMAT MAC112C-0-ED-2-C/130-B-0 motors to replace obsolete DC servos. The switch eliminated brush maintenance and enabled 5-axis interpolation at 0.5 µm resolution. Production throughput rose by 18%, and FDA audit readiness improved due to consistent motion logs from the resolver feedback. Similarly, in a Swiss watch assembly line, the motor’s sub-millisecond response and minimal vibration allowed delicate gear insertion without micro-fractures—reducing yield loss by $380K annually.
