MAC112D-0-FD-1-B/130-A-1/I1250/S05

The MAC112D-0-FD-1-B/130-A-1/I1250/S05 AC servo motor from Bosch Rexroth Indramat sits at the forefront of the MAC AC Servo Motors series, combining robust construction with precise control features. This model offers a rated speed of 2000 rpm and delivers a continuous torque of 38 Nm under natural cooling at standstill, driven by a continuous current of 56 A. The housing features a black prime coat (RAL 9005) finish for superior corrosion resistance and is rated IP65 for environmental protection. Engineered for reliability, this motor incorporates tacho feedback and interfaces seamlessly with TDM, KDS, and DSC drive controllers for rapid response in dynamic applications. The result is a compact yet powerful solution tailored for high-performance automation tasks.

The technical capabilities of this servo motor are underpinned by its advanced electrical and mechanical design. The winding resistance of 0.110 ohms and winding inductance of 1.8 mH enable efficient current handling and dynamic responsiveness, further enhanced by a torque constant of 0.760 Nm/A. A maximum peak of pulse current of 260 A ensures short bursts of high torque when required, supported by a moment of inertia of 230 x 10^-4 kgm² derived from its permanent magnet configuration. Thermal management is achieved through natural convection cooling and monitored by thermo switches integrated into the motor windings and stator housing, with a thermal time constant of 120 minutes providing excellent overload tolerance. Built on a motor size 112 frame with motor length D, this 59-kilogram unit balances durability and performance for sustained operation.

Operationally, the motor’s features translate into dependable and efficient performance in demanding environments. The Insulation Class F rating allows for sustained high-temperature operation, while the IP65 protection rating guards against dust and water ingress. Its housing design facilitates external heat dissipation via natural convection, maintaining optimal temperature without auxiliary cooling. An integrated heavy-duty holding brake weighing 1.1 kg, operating at 24 V nominal voltage and 0.75 A nominal current, secures loads reliably when power is removed. The A-side power connection simplifies installation and cable routing, and a wide operating temperature range of –20 to +80 °C ensures versatility across industrial settings.

Integration of the MAC112D motor into automation systems is straightforward, leveraging its compatibility with Bosch Rexroth’s DSC, TDM, and KDS drive controllers for advanced control schemes. Its standardized motor size and length, combined with high-precision tacho feedback, enable accurate synchronization in multi-axis setups. Ideal applications include machine tools, packaging machinery, robotics, handling equipment, and transfer systems where precision and fast response are paramount. With its combination of robust protection, precise feedback, and seamless controller integration, this servo motor represents a versatile solution for engineers seeking high-performance motion control.
