MAC112A-0-LD-3-C/130-A-1/S014

The MAC112A-0-LD-3-C/130-A-1/S014 is a high-performance servo motor from Bosch Rexroth Indramat within the MAC AC Servo Motors series, designed for demanding industrial automation tasks. This three-phase MAC Permanent Magnet Motor delivers a nominal motor speed of 3000 min^-1 and features a compact Motor Size 112 with Motor Length A, ensuring a balanced footprint and power density. The unit incorporates a power connector on Side A for streamlined cabling and an integrated standard blocking brake to guarantee safe and immediate stopping under load. Cooling is handled via Natural Convection to maintain optimal thermal conditions without auxiliary systems. Together, these characteristics make the MAC112A-0-LD-3-C/130-A-1/S014 an ideal solution for installations where space, safety, and performance converge.

Technically, the motor offers a continuous current at standstill of 31 (41.3) A and a corresponding continuous torque at standstill of 9.8 (13.0) Nm, enabling robust startup performance. It can withstand a maximum peak of pulse current of 130 A for brief high-load demands and boasts a torque constant at 20 °C of 0.350 Nm/A for precise torque delivery per ampere. The electrical design includes a windings inductance of 1.9 mH and a windings resistance at 20 °C of 0.180 ohm, optimized for rapid current changes and minimal thermal losses. The rotor’s dynamic behavior is characterized by a rotor moment of inertia of 61 x 10^-4 Kgm^2, providing excellent acceleration response, while the thermal time constant of 100 (75) min ensures reliable operation under varying duty cycles. With a total mass of 25 kg, the motor balances structural rigidity with manageable installation weight.

Operationally, the MAC112A model excels in applications requiring precise speed regulation and repeatability. The inclusion of an A encoder on the second shaft end supplies high-resolution feedback, while an optional tacho interface enhances real-time speed monitoring. Surface cooling by natural convection maintains the motor within ideal temperature ranges, preventing overheating during continuous operation. The integrated blocking brake delivers immediate, fail-safe stops, minimizing drift and ensuring positional integrity in safety-critical environments. Collectively, these features translate to reduced maintenance, lower downtime, and enhanced overall system efficiency.

For system integrators, the motor’s standard power connector on Side A and compatibility with type C tacho feedback facilitate straightforward mechanical and electrical mounting. The MAC112A-0-LD-3-C/130-A-1/S014 interfaces seamlessly with Bosch Rexroth drives and controllers, supporting advanced control algorithms and automated parameter tuning. Its combination of high torque density, precise feedback, and inherent protection makes it suitable for CNC machinery, robotics, packaging lines, and any high-precision motion control application where reliability and performance are paramount.
