Product Description:

Bosch Rexroth Indramat engineered the MAC112B-0-LD-4-C/130-A-1/DI522LV as a servo motor in the MAC AC Servo Motors series. Designed for analog drive modules, the unit converts amplifier output into regulated torque and speed for automated machine axes. By providing rapid response and repeatable positioning, it supports coordinated motion on conveyors, packaging lines, and metal-cutting equipment where accurate cyclic operation is essential.

The mechanical interface uses a flange with a 130 mm centering diameter, a dimension that aligns the stator housing precisely to the adjoining machine frame and helps minimize radial runout. A blocking brake rated at 45 Nm resists back-driving when the axis is idle, holding vertical or oscillating loads without external clamps. Internal copper windings follow the LD code, indicating the electrical resistance and inductance used with standard MAC amplifiers. Shaft speed under rated load reaches 2000 rpm, giving a usable velocity range for coarse positioning and continuous rotation tasks. Heat produced by losses is removed through natural convection, so installation must permit free airflow around the motor's ribbed housing. The unit carries the B length code, which indicates its axial stack dimension within the frame.

Electrical integration is simplified by a power connector routed on side A, allowing short cable runs inside a control cabinet. The motor has a frame size of 112, which matches the shaft height commonly used on mid-power machining axes. A built-in standard blocking brake engages automatically when supply power is removed. Tachogenerator output equals 3 V/1000 rpm, delivering proportional speed feedback with standard tacho quality. Additional position information comes from an incremental encoder mounted in a shock-damped support.
