Product Description:

The MAC112D-0-ED-4C/130-A-2/S018/MR121 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Built for closed-loop axis control, this unit converts electrical command signals into precise rotary motion for packaging, tooling, and material-handling equipment. Its construction focuses on maintaining constant torque response, which helps the motor stay predictable during repeated starts, stops, and speed changes. The unit is intended to operate with analog drive amplifiers that regulate current externally for controlled motion. This makes it suitable for mid-power positioning duties where accurate response and steady speed regulation are more important than unusually high overload capacity.

Heat removal relies on natural convection, so the installation must allow unobstructed airflow around the housing instead of depending on forced cooling. The rotor can sustain a synchronous mechanical speed of 3000 rpm, giving the axis a useful operating range for positioning moves and short acceleration periods. A 112 stator frame with D length balances torque density and rotor inertia, which helps the motor deliver responsive motion without excessive bulk. That frame combination gives the motor a solid mechanical envelope for continuous industrial use while keeping inertia within a manageable range for general automation axes. Positional data is provided through a factory-installed incremental or absolute encoder with tachogenerator feedback, allowing the connected drive to use analog speed feedback or digital position channels. Energization characteristics follow the ED winding code, which identifies the electrical winding layout used for the intended amplifier range.

This unit is classified as a motor for analog drives, so it is suited to motion systems that rely on external current regulation rather than integrated digital power electronics. The available feedback arrangement supports both speed monitoring and position tracking, which is useful on machines that need stable motion control across varied operating cycles. Its operating profile fits indexing axes, transfer mechanisms, and other servo applications where repeatable response matters more than specialized cooling hardware. In those roles, the motor can support smooth acceleration behavior and consistent correction of load-related speed deviations by the connected control system.
