Product Description:

The MAC112D-1-ED-1-B/130-A-1 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. Classified as a motor for analog drives, it converts drive-controller current into controlled shaft rotation for position or speed loops in automated equipment. Within an automation cell, this servo motor provides the electromechanical link between the electronic command signal and the mechanical load. It is suited for positioning and speed-control tasks in packaging, transfer, and general automation equipment where repeatable rotary motion is required.

A standard blocking brake supplies 45 Nm of holding torque when the axis is stationary, helping prevent unintended motion after power is removed. Thermal regulation is assisted by a blower that operates from AC 230 V, and its airflow supports the motor’s axial surface cooling path so continuous duty can be maintained without excessive heat buildup. Accurate mounting is aided by a centering pilot of 130 mm, which helps keep alignment between the motor flange and the driven machine. Under nominal conditions, the rotor reaches 3000 rpm to balance torque production with dynamic response in analog control loops.

The feedback chain starts with a shaft-mounted incremental encoder that sends position pulses to the analog drive, and an internal tacho generator outputs 3 V/1000 rpm to provide a direct velocity reference. Electrical characteristics follow winding code ED, while the mechanical format uses size 112 and the D length option to suit installations with matching inertia and installation depth. Main power reaches the stator through a connector on side A, which can simplify cable routing when several motors are installed in the same cabinet. This layout supports orderly separation of power and feedback leads and helps the motor fit compact axis arrangements.
