MAC112B-1-GD-4-C/130-B-0/DI524LV/S022

The MAC112B-1-GD-4-C/130-B-0/DI524LV/S022, manufactured by Bosch Rexroth Indramat, is a permanent magnet servo unit in the MAC AC Servo Motors series. It integrates a power connector on Side B and features a high-resolution B encoder, while its blocking brake interface remains unequipped for custom brake solutions. Designed for analog drive architectures, this motor delivers precise position control with exceptional repeatability. Its rugged build supports continuous operation in industrial environments without compromise.

Featuring a Motor Size of 112 and a Motor Length of B, the motor operates at a nominal motor speed of 3000 min^-1 and produces a continuous torque at standstill of 16 (29)^5) Nm under a continuous current at standstill of 41 (75)^5) A. Transient performance is assured by a maximum peak of pulse current of 223 A and a torque constant at 20 degrees C of 0.430 Nm/A, enabling rapid torque buildup. The drive’s electrical behavior is characterized by a windings resistance at 20 degrees C of 0.090 ohm and windings inductance of 1.2 mH, while a rotor moment of inertia of 120 x 10^-4 Kgm^2 balances acceleration with load stability. Thermal management is optimized through a thermal time constant of 90 (60)^5) min in conjunction with Cooling Type Surface Cooled, and the overall Mass of 36 kg simplifies mounting logistics.

Engineers will appreciate the motor’s IP65 protection rating and insulation classification F for enduring reliability in dusty or wet settings. Seamless integration into CNC mills, robotic axes, or packaging lines is achieved via standard flange interfaces and analog feedback signals. The MAC112B-1-GD-4-C/130-B-0/DI524LV/S022 combines durable construction, precise feedback, and efficient thermal design to minimize downtime and maximize throughput across demanding applications.
