MAC093C-1-FS-2-C/130-B-0/S012

The MAC093C-1-FS-2-C/130-B-0/S012 permanent magnet AC servo motor from Bosch Rexroth Indramat is a precision drive solution in the renowned MAC AC Servo Motors series, engineered for dynamic industrial motion applications. This unit features a Motor Size 93 and Motor Length C housing, optimized for high torque density in a compact footprint. With a Continuous current at standstill of 35 A (50 A peak) and a Torque constant at 20°C of 0.579 Nm/A, the motor delivers a Continuous torque at standstill of 19.5 Nm (28.0 Nm peak) for robust startup performance. Rated for a Nominal motor speed of 3000 min^-1, the drive maintains stable operation across standard servo control profiles. The motor’s Cooling Type: Surface Cooled architecture ensures efficient thermal management without the need for auxiliary cooling infrastructure, contributing to a lightweight overall mass of 22 Kg. Designed with a Maximum peak of pulse current of 173 A, this motor readily accommodates rapid acceleration demands while maintaining precise control.

Performance characteristics are defined by meticulous electromagnetic design and advanced material selection. The Windings inductance of 2.9 mH combined with a Windings resistance at 20°C of 0.175 Ω results in favorable electrical time constants that enhance current responsiveness. A Rotor moment of inertia of 42 x 10^-4 kg·m² achieves a balanced compromise between dynamic acceleration and load inertia matching. The motor’s Thermal time constant of 50 min (45 min under peak load) ensures predictable heat dissipation over extended duty cycles, facilitating high-duty-point operation without thermal overload. The inclusion of a C encoder provides high-resolution position feedback necessary for closed-loop control, while the absence of a blocking brake reduces mechanical complexity. The drive’s rated current profile supports rapid torque modulation, enabling precise motion profiles in high-precision tasks.

Reliability and system integration are paramount in the MAC093C series. The integrated power connector on Side B streamlines field installation, minimizing wiring errors and reducing commissioning time. A ruggedized internal fan blower maintains optimal operating temperatures even under sustained high-load conditions, enhancing long-term durability. The motor’s modular interface and standardized dimensions allow direct replacement or upgrade within existing MAC series installations, preserving system continuity. Ideal for applications in robotics, automated assembly, pick-and-place systems, and machine tool spindles, this servo motor delivers consistent performance and simplified integration in demanding industrial environments.
