Product Description:

The MAC112D-0-ED-3-C/130-A-2/S018 AC servo motor is produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is classified as a motor for analog drives that turns electrical control signals into mechanical rotation for positioning axes, indexing tables, and other automation tasks in general machine building. Within production cells, it converts current-regulated commands from Indramat drive controllers into precise torque for closed-loop movement of sliders, gantries, and spindle modules. Its operating role is to follow changing command values smoothly so machine axes can accelerate, hold speed, and stop in a controlled manner. That behavior is useful where the same axis must repeat short moves and dwell positions throughout a production cycle.

It contains a heavy-duty blocking brake that immobilizes the shaft whenever the drive is disabled. The brake develops 60 Nm of holding torque, which secures vertical loads at rest. During continuous operation, the rotor turns at a nominal speed of 3000 rpm, aligning with medium-inertia machinery and standard 50/60 Hz inverter outputs. Heat is removed through natural convection, so the enclosure needs free airflow and no auxiliary fans. Because cooling is passive, the motor housing can dissipate heat without external air ducts. A centering pilot of 130 mm aligns the housing on the mounting face and helps maintain concentricity with connected mechanics. The ED winding code identifies the electrical characteristics used by compatible drive amplifiers.

All service connections are consolidated on one face, and the power leads exit through a connector on side A, which can simplify cabinet layout. Motion feedback is provided by built-in tacho feedback with a second shaft end, giving analog velocity information while leaving the primary shaft free for couplings or encoders. The generator outputs 3 V/1000 rpm, allowing the analog drive to calculate actual speed without digital interpolation. This supports proportional control loops and slip monitoring during steady running and speed changes.
