MAC093C-1-KS-3-C/110-B-0

The MAC093C-1-KS-3-C/110-B-0 is a high-performance AC servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series. This AC Servo Motor features a compact Motor Size 93 housing with a Motor Length C profile and a robust, Surface Cooled design. The unit delivers a continuous current at standstill of 22 A (peak 32 A) and generates a continuous torque at standstill of 19.5 Nm (peak 28 Nm). With a mass of 22 kg and a centering diameter of 110 mm for B05/B14 flange configurations, it provides an excellent power-to-weight ratio. The power connection is located on Side B, and the motor includes a C encoder and is not equipped with a braking system.

Performance is driven by a nominal motor speed of 2000 min^-1 paired with a tacho generator output of 3 V/1000 min^-1 for precise speed feedback. The torque constant at 20 °C is 0.910 Nm/A, supported by a windings inductance of 7 mH and a windings resistance at 20 °C of 0.443 Ω. This configuration yields smooth torque delivery and rapid current response, with a maximum peak of pulse current reaching 110 A. The rotor moment of inertia of 42 x 10^-4 kg·m^2 ensures stable dynamic behavior under varying load conditions, while the thermal time constant of 50 min (45 min for continuous operation) enables sustained duty cycles. Together, these characteristics enable precise motion control, minimal torque ripple, and reliable performance in high-demand applications.

Reliability is assured by the motor’s robust construction and optimized cooling characteristics, which maintain consistent operation across extended duty cycles. Integration into automation systems is streamlined by the standardized flange interfaces and electrical connections on Side B, facilitating quick assembly and minimal downtime. The surface-cooled design reduces maintenance requirements and extends service intervals in environments where continuous operation is critical. Typical applications include robotics, material handling systems, packaging machinery, and CNC automation, where high torque density, precise feedback, and long-term reliability are essential. The MAC093C-1-KS-3-C/110-B-0 delivers the performance and durability required for demanding industrial motion control tasks.
