Product Description:

The MAC112D-0-ED-4-C/130-B-0/WI520LV/S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analogue drives where torque and velocity are regulated through voltage commands rather than fieldbus links. The motor ships in length class D and provides tachofeedback that can be combined with an incremental or an absolute encoder; the standard mounting accepts an incremental encoder for position loops. Its internal tacho generator is graded as standard quality, matching the precision usually required for general-purpose machine axes.

Mechanical interface details simplify alignment and coupling. A centering diameter of 130 mm allows the housing to seat firmly against a register on the machine frame, while the shaft is machined with a DIN 6885 keyway so pulleys or couplings lock without slipping. For wiring, the power leads exit through a connector on side B, keeping the motor profile clear on the drive-side of the machine. Heat is removed only by natural convection, so airflow around the fins must not be obstructed. Under rated conditions the rotor reaches a speed of 3000 min⁻¹, giving drive designers a direct conversion between command voltage and mechanical output frequency.

Electrical parameters complete the selection data. The frame is classified as size 112, and its stator carries winding pattern ED, a combination that defines the current and voltage set required from the analogue drive. The motor is supplied without a blocking brake, so vertical axes must rely on external holding devices if power is removed. During rotation the built-in tacho generator outputs 3 V per 1000 min⁻¹, a value used by the drive card to generate speed feedback for closed-loop regulation. These characteristics enable the motor to integrate into power cabinets that already support MAC windings while leaving mounting and cooling demands unchanged.
