Product Description:

The MAC112D-0-FD-4-C/130-B-1/DI524LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drive systems where precise velocity and position control are required on assembly lines, gantries, and tooling equipment. The model converts electrical command signals into controlled rotary output and includes an integrated blocking brake to secure motion when power is off, supporting safe stops in vertical or load-holding axes. This arrangement helps the connected drive maintain stable motion control without adding separate external holding hardware at the axis.

The blocking brake delivers 45 Nm, giving the motor enough static torque to resist back-driving under load. A flange centering diameter of 130 mm aligns the housing concentrically with machine frames, which helps reduce radial misalignment and bearing stress. Cooling relies on natural convection, so thermal energy leaves the stator through the surface fins without added fans or liquid jackets. Under rated excitation, the rotor reaches 2000 rpm, a speed that matches many coarse-pitch screw or belt transmissions. Winding code FD indicates the conductor gauge, turn count, and impedance values used with compatible analog amplifiers.

The tachogenerator produces 3 V/1000 rpm, supplying the controller with proportional voltage feedback for continuous speed regulation. For position feedback, the shaft carries an incremental encoder secured by a shock-damping fixture that helps protect the disk from sudden torsional impulses. Motor power is routed through a connector on side B, which helps separate high-current paths from low-level signal wiring and keeps cable routing straightforward. The motor has a frame size of 112 with D length, giving it a larger housing that supports higher torque output while preserving the mounting style used in the MAC motor line.
