MAC112B-1-GD-4-F/130-A-1/WI524LV

The Bosch Rexroth Indramat MAC112B-1-GD-4-F/130-A-1/WI524LV from the MAC AC Servo Motors series by Bosch Rexroth Indramat is engineered for demanding industrial applications requiring precise speed and torque control. This high-dynamic servo motor delivers a continuous current at standstill of 41 A and a continuous torque at standstill of 16 Nm, with a torque constant of 0.430 Nm/A measured at 20 °C. Spinning at a nominal motor speed of 3000 min^-1, the unit supports rapid acceleration and deceleration profiles, making it suitable for high-speed automation tasks. The integrated incremental encoder and standard blocking brake ensure reliable feedback and safe holding under load.

Reliability is reinforced by a robust rotor moment of inertia of 120 x 10^-4 Kgm^2, which stabilizes motion during transient events, and a thermal time constant of 90 min that defines its heat dissipation capability under continuous operation. The copper windings exhibit a resistance at 20 °C of 0.090 ohm and an inductance of 1.2 mH, enabling fine-tuned current regulation and low electrical time constants. For brief torque peaks, the motor tolerates a maximum peak of pulse current of 223 A, delivering exceptional dynamic performance. This configuration supports extended duty cycles and minimizes thermal derating in compact drives.

Mechanical versatility is provided by a motor size of 112 and motor length B, fitting standard B05 and B14 mounting patterns with a centering diameter of 130 mm. The motor’s mass of 36 kg balances inertia and payload requirements, while the surface cooled design, driven by axial fans, dissipates generated heat over a wide exposed area. Altogether, the MAC112B-1-GD-4-F/130-A-1/WI524LV stands as a high-precision, heavy-duty servo solution optimized for harsh environments and high-speed, torque-intensive operations.
