MAC112B-0-GD-4-C/130-A-1/WA612XX

The Bosch Rexroth Indramat MAC112B-0-GD-4-C/130-A-1/WA612XX permanent magnet AC servo motor from the MAC AC Servo Motors series delivers precision motion control through high torque density and robust industrial design. This motor integrates a Standard blocking brake and a B encoder for reliable positioning and fail-safe holding capabilities. With a nominal speed of 3000 min⁻¹ and a continuous torque of 9.8 (13.0) Nm, it supports demanding acceleration profiles and sustained load operation. The unit’s power connector on Side A simplifies electrical interfacing in compact installations. Featuring a black RAL9005 housing and shock-absorbing construction, it is engineered for harsh environments and high-performance automation.

Detailed technical specifications define the MAC112B-0-GD-4-C/130-A-1/WA612XX for rigorous engineering applications. The motor achieves Continuous current at standstill: 31.0 (41.3) Amperes and withstands a Maximum peak of pulse current: 130 Amperes for transient loads. It exhibits a Torque constant at 20 °C: 0.350 Nm/A and a Rotor moment of inertia: 61 × 10⁻⁴ kg·m², facilitating precise dynamic response. Electrical characteristics include Windings inductance: 1.9 mH and Windings resistance at 20 °C: 0.180 Ω. Thermal management is quantified by a Thermal time constant: 100 (75) min, while the overall Mass: 25 kg ensures structural stability. The motor’s Motor Size: 112 and Motor Length: B dimensions conform to industry standards, and its Cooling Type: Natural Convection supports maintenance-free operation.

Operational features emphasize durability and consistent performance under challenging conditions. An IP65 protection grade safeguards against dust and water ingress, and the F-Class insulation enhances thermal endurance up to high ambient temperatures. The motor’s plain or keyed shaft enables flexible mechanical coupling, while the integrated blocking brake provides emergency hold. A dedicated power connector on Side A and compatibility with screw fixation encoders streamline installation. The rugged housing finish (RAL9005) and shock-absorbing design extend service life in vibration-intensive environments.

System integration is straightforward with common servo drives and motion controllers, making the MAC112B-0-GD-4-C/130-A-1/WA612XX suitable for CNC machinery, grinding machines, and precision lathes. Its high torque-to-inertia ratio and encoder feedback support advanced control algorithms and rapid tuning. Ideal target applications include robotics, packaging systems, and automated assembly lines where reliability, accuracy, and compact footprint are critical.
