Product Description:

The MAC112D-0-ED-3-C/180-A-2/S019 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is a motor for analog drives that converts drive controller commands into rotary motion for positioning and velocity tasks on machine axes. In automated production lines, it supplies closed-loop speed and torque so mechanical loads can be moved accurately without overshoot. Its operating concept suits transfer, indexing, and handling equipment that depends on repeatable motion and steady response under changing loads.

This model employs a heavy-duty blocking brake that holds the shaft when power is removed, and its braking torque is rated at 60 Nm, allowing vertical or safety-critical axes to stay locked during downtime. Cooling relies on natural convection, so the housing surface dissipates heat without auxiliary fans and cabinet airflow planning remains straightforward. The nominal speed reaches 3000 min⁻¹, giving a balance between dynamic response and mechanical life for mid-range servo applications. Mounting is aligned by a 180 mm centering diameter that fits the corresponding machine flange with minimal runout. The D-length stator provides additional winding volume, which supports the motor’s operating characteristics in this frame.

Tacho feedback on the second shaft end supplies a reference signal of 3 V/1000 min⁻¹, and the standard tacho quality supports stable velocity loops in legacy control systems. Power conductors enter through a connector on side A, which can simplify cable routing in cabinets where drives are stacked horizontally. The motor has a frame size of 112, and winding code ED identifies the electrical configuration used in this version. This arrangement supports integration with matching analog servo components and conventional axis layouts.
