MAC090B-0-PD-2-C/110-A-0/S015

The MAC090B-0-PD-2-C/110-A-0/S015 is part of the renowned MAC AC Servo Motors lineup by Bosch Rexroth Indramat, engineered for precision motion control in demanding industrial environments. This permanent magnet motor delivers a nominal motor speed of 2000 RPM with a continuous torque at standstill of 7.2 Nm, driven by a continuous current at standstill of 11.9 A. The unit’s robust construction yields a mass of 18 Kg and a rotor moment of inertia of 53 x 10^-4 kg·m², ensuring stable and repeatable operation. Equipped with a side-A power connector and a B-type encoder interface, it supports feedback via a 12-pin flanged socket for tachometer and encoder signals. The compact footprint, defined by Motor Size 90 and Motor Length B, aligns with DIN42950 B05/B14 flange standards for simplified mechanical integration.

Performance is enhanced by a suite of finely tuned electrical and thermal characteristics. The torque constant at 20 °C of 0.68 Nm/A couples with a windings inductance of 3.6 mH and a windings resistance at 20 °C of 0.60 Ω to deliver smooth, precise torque under dynamic load changes. Peak demands are met by a maximum peak of pulse current of 86 A, while the thermal time constant of 60 min governs heat dissipation through natural convection cooling. The permanent magnet design minimizes rotor inertia and maximizes torque density, and the absence of a blocking brake reduces complexity where holding torque is not required. These features work in concert to provide rapid response, high accuracy, and energy efficiency in cyclic and continuous-duty applications.

Built for integration into CNC machine tools, robotics, packaging machinery, and automotive production lines, the MAC090B-0-PD-2-C/110-A-0/S015 offers proven reliability and ease of installation. The natural convection cooling system eliminates external cooling hardware, relying on the standard thermal design to maintain optimal operating temperatures. Compliance with DIN standards for shaft keyways and mounting flanges facilitates direct replacement or system upgrades without custom adapters. This motor’s balanced combination of performance, robustness, and standardized interfaces makes it an ideal choice for high-precision motion control tasks in facilities where uptime and accuracy are paramount.
