MAC112B-0-GD-4-C/130-A-2/WA610XX/S013

The Bosch Rexroth Indramat MAC112B-0-GD-4-C/130-A-2/WA610XX/S013 AC motor from the MAC AC Servo Motors series delivers a robust combination of precision, durability, and ease of integration for industrial automation. Featuring a permanent magnet rotor design, this unit provides high torque density and consistent performance at rated conditions. The motor’s compact Motor Size: 112 and Motor Length: B make it suitable for systems where space constraints are critical without sacrificing power output. A power connector on Side A and an integrated B encoder with tachometer feedback ensure accurate position and speed monitoring in real time. The inclusion of a heavy-duty incremental/absolute encoder blocking brake enhances safety and load-holding capability under dynamic conditions.

Detailed electrical and mechanical specifications define the MAC112B’s capabilities. It delivers a Continuous current at standstill: 41 A (75 A peak) and a Continuous torque at standstill: 16 Nm (29 Nm peak) to handle high-load scenarios. The motor sustains a Nominal motor speed: 3000 min^-1 and can absorb a Maximum peak of pulse current: 223 A for rapid acceleration demands. The Rotor moment of inertia: 120 x 10^-4 kg·m² balances responsive control with mechanical stability. The winding assembly features a Windings inductance: 1.2 mH and Windings resistance at 20°C: 0.090 Ω to optimize current flow and minimize losses. Thermal management is governed by a Thermal time constant: 90 min (60 min peak), supporting continuous operation under convection cooling. The Torque constant at 20°C: 0.430 Nm/A ensures predictable torque generation for precise motion profiles. Mass and structural data include a Mass: 36 kg, reflecting the motor’s robust construction.

Operational performance of the MAC112B includes natural convection cooling that leverages the frame structure for heat dissipation without auxiliary fans. The Cooling Type: Natural Convection maintains winding and magnet temperatures within safe limits during prolonged duty cycles. Tacho feedback paired with an integrated encoder (type C) provides high-resolution speed control and position tracking, minimizing overshoot and settling time in dynamic motion sequences. The heavy-duty blocking brake supports frequent engagement cycles, holding torque under power-off conditions to secure driven loads. This feature is critical in applications requiring immediate stop-and-hold capability, such as safety interlocks or vertical axis drives. Vibration damping and mechanical rigidity ensure stable operation even under fluctuating load profiles.

Integration into motion control systems is streamlined through standard flange and shaft dimensions, including the 130 mm centering diameter for both B05 and B14 mounting patterns. The encoder interface supports incremental or absolute feedback, enabling compatibility with a broad range of servo drives and controllers. Ideal use cases for the MAC112B-0-GD-4-C/130-A-2/WA610XX/S013 include CNC machine tools, robotics, packaging machinery, and material handling systems where precise torque control and reliable load holding are paramount. The seamless interoperability with Bosch Rexroth Indramat drive electronics further reduces commissioning time and enhances system-level diagnostics.
