MAC112B-2-LD-3-C/130-A-0

The MAC112B-2-LD-3-C/130-A-0 by Bosch Rexroth Indramat is part of the MAC AC Servo Motors series and features a robust Motor Size 112 frame in a compact Motor Length B configuration. Designed as a high-performance AC Servo Motor, it employs a Surface Cooled heat dissipation method that ensures efficient thermal management in demanding applications. With an integrated encoder interface and a power connector on Side A, it simplifies installation and maintenance workflows. This permanent magnet motor model supports analogue drive systems and is optimized for precise positioning tasks.

The motor delivers a Continuous current at standstill of 26.3 A and achieves a substantial Continuous torque at standstill of 17.5 Nm for load-holding and start-up operations. It can withstand short-term surges up to a Maximum peak of pulse current of 130 A, while its Nominal motor speed of 2000 min^-1 ensures reliable speed control across varying load profiles. The Torque constant at 20 degrees C of 0.740 Nm/A provides predictable current-to-torque conversion, and the windings exhibit a Windings inductance of 3.5 mH coupled with a Windings resistance at 20 degrees C of 0.260 ohm. Such electrical characteristics yield tight regulation and fast dynamic response in motion-control circuits.

Mechanically, the unit weighs 36 kg, delivering a solid and vibration-resistant solution for compact machine designs. The Rotor moment of inertia of 120 x 10^-4 Kgm^2 is tailored to support high-acceleration profiles without compromising positional accuracy. Thermal stability is reinforced by a Thermal time constant of 90 min, enabling extended duty cycles under cyclic loading conditions. Together, these attributes make the MAC112B-2-LD-3-C/130-A-0 a versatile choice for precision automation, robotics, and packaging machinery where consistent torque, smooth operation, and easy serviceability are essential.
