MAC112D-0-ED-1-B/130-B-0/I01250/S05

The Bosch Rexroth Indramat MAC112D-0-ED-1-B\/130-B-0\/I01250\/S05 permanent magnet synchronous motor from the MAC AC Servo Motors series combines precision engineering with robust industrial design to meet the rigorous demands of modern automation. This servo motor employs electronic commutation in a brushless configuration to deliver consistent performance under varying loads. Featuring an integrated tacho feedback generator, it provides accurate monitoring of speed, position, and torque, enabling real-time control adjustments. Compactly housed and designed for harsh environments, it maintains reliable operation while minimizing downtime and maintenance.

The MAC112D-0-ED-1-B\/130-B-0\/I01250\/S05 incorporates a range of critical parameters to optimize motion control. It delivers a continuous torque at standstill of 35Nm while drawing a continuous current at standstill of 63A, and operates at a nominal speed of 3000min-1 under rated conditions. The winding resistance at 20°C is precisely maintained at 0.070Ohms, with a winding inductance of 1.0mH to ensure stable current dynamics. Thermal management is handled via natural convection cooling, supported by a thermal time constant of 120min, allowing for predictable temperature behavior. The robust design adheres to Protection Class IP65, safeguarding internal components against dust and water ingress.

Operational performance is further enhanced by a torque constant at 20°C of 0.620Nm/A, which defines the motor’s responsiveness to current input changes. The motor’s mass of 59kg and motor size 112 profile provide the structural inertia required for smooth acceleration and deceleration cycles. An output shaft featuring a sealed ring and keyway design supports high radial loads, ensuring reliable torque transmission to driven machinery. In the absence of a blocking brake, the motor relies on its inherent magnetic design for spark-free stopping behavior. Integration with Rexroth drive controllers such as TDM, KDS, or DSC completes a rapid-response drive system optimized for precision tasks.

System integration of the MAC112D-0-ED-1-B\/130-B-0\/I01250\/S05 servo motor is streamlined through compatibility with standard Rexroth communication protocols and drive platforms. Its brushless, synchronous design eliminates the need for periodic maintenance of commutation components, reducing lifecycle costs. Target applications include machine tools, packaging systems, and industrial automation lines where high precision, environmental resilience, and adaptive performance are critical. With its blend of robust specifications and versatile control features, this motor serves as a foundational element for advanced motion control solutions.
