MAC112C-1-KD-4-C/130-B-1/DI524LV/S014

The Bosch Rexroth Indramat MAC112C-1-KD-4-C/130-B-1/DI524LV/S014 is a robust permanent magnet AC servo motor in the MAC AC Servo Motors series, engineered for precision motion control and high dynamic performance. This MAC Permanent Magnet Motor features a power connector on Side B for streamlined cabling and serviceability, and is equipped with a C incremental encoder and a Standard blocking brake to ensure reliable position feedback and fail-safe holding. With a centering diameter of 130 mm (designs B05 and B14), the MAC112C-1 motor maintains exceptional alignment and minimizes vibration, making it ideal for high-accuracy applications. Its surface cooled design combined with a motor length designation of C provides efficient heat dissipation, supporting prolonged operation under demanding conditions. Weighing 48 kg, it balances structural stability with performance, facilitating integration into mid- to large-sized automation systems.

Detailed technical specifications define the motor’s electrical and mechanical parameters. The servo motor delivers a continuous current at standstill of 31.0 A (up to 49.0 A under specific conditions), yielding a continuous torque at standstill of 28.0 Nm (up to 44.0 Nm). It sustains a maximum peak of pulse current of 141 A for rapid torque bursts. The nominal motor speed is 1500 min^-1, optimized for smooth operation at rated load. The rotor moment of inertia is 170 x 10^-4 kg·m^2, balancing dynamic response and load stability. The torque constant at 20°C of 1.000 Nm/A ensures predictable torque generation, while the windings inductance of 4.5 mH and windings resistance at 20°C of 0.270 Ω define the motor’s current control characteristics. A thermal time constant of 100 min governs winding temperature rise under continuous loading, enabling accurate thermal management strategies.

Operational features emphasize performance under real-world conditions. The motor’s surface cooling mechanism maintains winding temperature within acceptable limits, leveraging the Surface Cooled design to mitigate thermal drift during extended operation. High peak pulse capability (141 A) allows instantaneous torque delivery for rapid acceleration and dynamic positioning, supported by the low rotor inertia (170 x 10^-4 kg·m^2), which reduces settling times. The combination of a precise C incremental encoder and a Standard blocking brake provides closed-loop accuracy and secure holding torque when deenergized, preventing drift in vertical or high-inertia applications. Consistent continuous torque output (28.0 Nm) at standstill, alongside a robust torque constant (1.000 Nm/A), ensures reliable performance in repetitive start-stop cycles and torque-controlled processes.

System integration is facilitated by the widely adopted MAC interface and compatibility with Bosch Rexroth Indramat drive controllers, enabling plug-and-play commissioning and advanced diagnostics. The standardized power connector on Side B simplifies wiring layouts, while the motor’s 112 size and C length conform to existing mounting architectures. Target applications include CNC machining centers, pick-and-place robotics, packaging machinery, and automated assembly lines where high precision, rapid response, and reliable holding are critical. The MAC112C-1 motor’s balance of dynamic performance, robust construction, and precise feedback makes it a versatile solution for demanding industrial automation environments.
