Product Description:

The MAC112C-0-ED-3-C/130-A-2/S013 is a servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, it interfaces with legacy current-controlled amplifiers to provide closed-loop motion on a wide range of production equipment. The motor supplies finely graduated rotation that supports precise positioning, speed holding, and incremental indexing in industrial automation. Its mechanical size C housing balances inertia and torque, making it suitable for medium-inertia loads that undergo frequent reversals.

Its stopping capability is secured by a heavy-duty blocking brake that delivers 60 Nm of static torque, allowing vertical or suspended loads to be held when power is removed. A centering pilot of 130 mm aligns the flange with gearboxes or adapter plates, while the frame designation 112 indicates the stator diameter and mounting compatibility across the series. The motor reaches a nominal speed of 3000 rpm, matching commonly used 50/60 Hz drive frequencies without additional gearing. Internal conductor size and insulation are identified by winding code ED, which sets the current rating and thermal limits for continuous duty.

Thermal regulation relies on natural convection, so cabinet layouts must allow unobstructed airflow along the housing fins. The feedback package combines a standard tacho generator, rated at 3 V/1000 rpm, with a second shaft end to couple external encoders when finer resolution is required. Power conductors enter through a connector on side A, keeping signal wiring separate on the opposite face and simplifying right-hand machine builds. This arrangement, along with the standard tacho package and motor length C, supports predictable response characteristics without requiring external blowers or liquid cooling.
