Product Description:

The MAC112D-0-ED-1B/130-A-1/J1250/S005 is an AC servo motor engineered by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed to work with compatible drive amplifiers, it converts electrical energy into rotary motion for axes that need precise acceleration, positioning, or steady speed in automated production lines. In service, the motor can drive feed axes, transport rollers, and indexing units that must start and stop smoothly under changing loads. By accepting proportional current commands, it supports stable speed and torque control in packaging, printing, and material-handling equipment.

Its thermal management relies on natural convection, meaning the aluminum frame dissipates heat directly to surrounding air. This makes fanless operation practical in cabinets where airflow is limited and where fewer moving cooling parts are preferred. Rotor position is monitored through incremental encoder feedback, allowing the controller to track motion with consistent resolution during acceleration, deceleration, and steady running. The electromagnetic circuit identified by winding code ED keeps copper loss moderate while supporting a rated speed of 3000 rpm, so the motor can respond quickly to changing demand. Permissible thermal loading depends on ambient temperature and mounting orientation, and adequate clearance around the housing is required for full cooling performance.

The mechanical outline combines motor length D with motor size 112, giving a housing depth and flange diameter that balance inertia and installation space. Because it is a motor for analog drives, the current command is supplied as a continuous reference signal, and the encoder provides a pulse train output that the drive converts into incremental counts for correction. This arrangement supports use with gearboxes or direct-drive linkages in systems that need repeatable motion without a separate cooling fan. It also allows the feedback path and power conversion stage to remain compact within the overall axis layout.
