MAC112B-0-GD-4-C/130-B-0/WI520LV/S021
The Bosch Rexroth Indramat MAC112B-0-GD-4-C/130-B-0/WI520LV/S021 is a robust AC servo motor engineered for demanding industrial applications. It operates at a speed of 3000 min⁻¹ and offers a constant standstill torque of 16.0 Nm, increasing to 29 Nm with surface cooling. The motor requires a continuous current of 41.0 Amperes, rising to 75.0 Amperes when surface-cooled, ensuring consistent performance across various operating conditions. With a rotor inertia of 120 x 10⁻⁴ kgm², the motor enables precise speed adjustments. Key specifications include a winding resistance of 0.090 Ohms, inductance of 1.2 mH, and a torque constant of 0.430 Nm/A at 20°C. It can manage load variations with a peak pulse current rating of 223 Amperes. The thermal time constant is 90 minutes, reduced to 60 minutes with cooling. Weighing 36 kg, it attaches with a B5 flange and handles industrial environments effectively, though care is needed to prevent liquid ingress near the shaft in certain mounting orientations.
