MAC093B-1-GS-3-C/110-B-2

The Bosch Rexroth Indramat MAC093B-1-GS-3-C/110-B-2 AC servo motor from the MAC AC Servo Motors series offers a compact, high-performance solution for demanding automation tasks. This MAC Permanent Magnet Motor features a power connector on Side B and includes an integrated B encoder, With Tachofeedback, and a second shaft-end blocking brake for precise, fail-safe operation. Its brushless design and lifetime-lubricated bearings deliver reliable service with minimal maintenance. The robust construction ensures consistent performance in harsh industrial environments, making the MAC093B-1-GS-3-C/110-B-2 ideal for continuous duty applications requiring dynamic response and accuracy.

Detailed technical specifications define the motor’s exceptional capabilities. It delivers a continuous current at standstill of 38 A and a continuous torque at standstill of 14.5 Nm, with a maximum peak of pulse current of 192 A for high-demand acceleration. The nominal motor speed of 4000 RPM provides rapid motion, while the rotor moment of inertia of 29 x 10^-4 kgm² supports stable control. The torque constant at 20 °C of 0.388 Nm/A, windings inductance of 2 mH, and windings resistance at 20 °C of 0.136 Ohm ensure predictable electrical behavior. Thermal management is addressed by a thermal time constant of 50 min, permitting sustained operation under elevated loads without overheating. Additional form-factor details include mass of 16.5 Kg, motor size 93, motor length B, and cooling type: Surface Cooled.

Operational features emphasize responsive control and durability. The brushless permanent-magnet topology minimizes rotor losses and extends service life, while the surface-cooled housing efficiently dissipates heat during continuous operation. The tachofeedback system combined with the high-resolution B encoder provides precise position and velocity feedback for closed-loop stability. The second shaft-end blocking brake secures the load in powered-off or emergency-stop conditions, eliminating drift and enhancing safety. Integration of a Side B power connector simplifies cabling and reduces installation time in compact drive cabinets.

System integration is streamlined for compatibility with Bosch Rexroth Indramat DCS, KDS, and TDM drive controllers, enabling advanced motion profiles, auto-tuning, and diagnostic functions. The MAC093B-1-GS-3-C/110-B-2 is especially suited for print machinery, packaging and labeling systems, robotic manipulators, CNC machine tools, material handling conveyors, and textile processing equipment. Its combination of high torque density, rapid response, and environmental resilience supports optimized cycle times and extended uptime. Engineers will appreciate the motor’s straightforward mounting interface and standard communication protocols, facilitating seamless incorporation into new and retrofit installations.
