Product Description:

The MAC112C-2-ED-2-C/130-A-1/S05 is a servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive controller commands into precise rotary motion for indexing tables, printing cylinders, and other closed-loop industrial axes. The model uses the 112 frame size and C length code, providing a balance between torque density and installation depth for medium-power machinery. It is intended for servo systems where analog command structure and integrated speed feedback remain part of the machine design.

Its mechanical interface uses a centering diameter of 130 mm, allowing concentric alignment with gearboxes or flanges. Internal heat is removed through axial surface cooling. An external blower operating at AC 115 V forces air along the housing fins so the motor can maintain continuous torque at elevated duty cycles. A built-in blocking brake rated at 45 Nm holds the shaft when power is removed, helping prevent back-driving on vertical or high-inertia loads. Under rated excitation, the rotor reaches 3000 rpm, which suits the speed range of common analog drive amplifiers while keeping motion smooth during normal operation.

The feedback chain relies on tacho feedback with standard tacho quality, supplying a proportional signal of 3 V/1000 rpm for velocity loops that use analog feedback rather than digital encoders. This type of signal works well in legacy motion systems that process continuous speed information directly at the amplifier input. Power conductors are routed through a connector on side A, which can simplify cabinet wiring when the motor is mounted with the fan facing the machine rear. Coil characteristics follow winding code ED, so the electrical resistance and inductance match compatible two-pole drive modules. That pairing helps the motor respond predictably to current commands across normal operating ranges.
