MAC112B-1-GD-4-C/130-L-1/WA608XX

The MAC112B-1-GD-4-C/130-L-1/WA608XX, Bosch Rexroth Indramat, MAC AC Servo Motors features a robust permanent magnet design engineered for demanding industrial automation. Equipped with a standard blocking brake and integrated B encoder, it ensures precise position feedback and immediate load holding when power is removed. The motor’s power connector is located to the left when viewed from the output shaft, streamlining mechanical integration in tight assemblies. This compact yet powerful unit offers reliable performance in robotics, conveyors, and multi-axis positioning systems.

In terms of detailed specifications, the motor delivers a continuous current at standstill of 41 A (75 A peak) and a continuous torque at standstill of 16 Nm (29 Nm peak) thanks to its high-performance windings. It withstands a maximum peak of pulse current of 223 A for brief torque surges and spins at a nominal motor speed of 3000 min^-1. The torque constant at 20 °C of 0.430 Nm/A, combined with a windings inductance of 1.2 mH and a windings resistance at 20 °C of 0.090 Ω, delivers smooth velocity control and rapid torque response. A rotor moment of inertia of 120×10^-4 kg·m^2 provides stability under acceleration, while a thermal time constant of 90 min (60 min for peak) ensures predictable thermal behavior during extended runs. With a mass of 36 kg, a motor size of 112, and surface cooling via axial fans, it balances power density and heat dissipation.

Engineers will appreciate how the MAC112B-1-GD-4-C/130-L-1/WA608XX integrates seamlessly into Rexroth Indramat control ecosystems, reducing cabinet space and wiring complexity. The heavy-duty blocking brake enhances safety by preventing unintended motion during maintenance and power failures, boosting operator confidence and protecting large loads. Overall, this servo motor delivers the reliability, precise control, and high torque needed for complex machining, packaging, and material handling applications.
