MAC AC Servo Motors
The Bosch Rexroth Indramat MAC112B-0-GD-4-C/130-A-1/WI518LV/S021 from the MAC AC Servo Motors series is a high-performance AC Servo Motor designed for precision industrial applications. It delivers a continuous current at standstill of 31.0 (41.3) Amperes and sustains a continuous torque at standstill of 9.8 (13.0) Nm. The unit handles a maximum peak of pulse current of 130 Amperes and spins at a nominal motor speed of 3000 min-1. With a torque constant at 20 °C of 0.350 Nm/A and a rotor moment of inertia of 61 x 10-4 kgm2, it ensures both dynamic response and stable motion under variable loading.
The design incorporates a windings inductance of 1.9 mH and windings resistance at 20 °C of 0.180 Ohm to optimize electrical performance and minimize losses. Its thermal time constant of 100 (75) min maintains reliable operation during cyclic loads. Cooled by natural convection, the motor frame (Motor Size 112, Motor Length B) is compact yet robust, weighing just 25 kg. These specifications support smooth acceleration and high repeatability, essential for robotics, CNC machining, and precision grinding applications.
Built for harsh environments, the MAC112B features an IP65 rating and F class insulation, reducing downtime in dusty or splash-prone conditions. The flange design with through-holes supports flexible mounting in IM B5 or IM B14 configurations. Together, these attributes make the MAC112B-0-GD-4-C/130-A-1/WI518LV/S021 an ideal choice for automated systems demanding accuracy, durability, and ease of integration.
