Product Description:

Bosch Rexroth Indramat produces the MAC112D-0-ED-2-C/180-A-0/S011 as an AC servo motor in the MAC AC Servo Motors series. It is intended for analog drive systems where precise velocity control is required in packaging, material-handling, and general factory automation tasks, especially where the drive must react smoothly to changing load conditions. The unit is supplied without a blocking brake, so any holding function during standstill must be provided by external locking hardware or by controlled motor torque from the connected drive.

The mechanical interface uses a centering diameter of 180 mm, allowing direct alignment with standard gearboxes or mounting plates during installation. Heat generated in the windings is removed through natural convection, eliminating the need for fans or liquid circuits. Rotor speed information is returned through integrated analog tacho feedback, which supports velocity loops in legacy analog controllers that rely on proportional speed signals. Under rated conditions, the shaft reaches 3000 rpm, which matches the base speed range commonly used with MAC amplifiers. Power and protective earth conductors enter the housing through a single connector on side A, simplifying cable routing in multi-axis machines.

The housing depth corresponds to motor length D, which gives the motor a longer active section than shorter versions in the same frame and supports higher continuous output within a similar footprint. Frame designation 112 sets the stator lamination height and the compatible shaft diameter used for this motor size. The tachogenerator produces 3 V/1000 rpm, giving the drive a linear feedback signal for speed calculation and stable analog loop operation. Winding code ED identifies the conductor gauge and turn count used by the matching analog amplifier, helping keep the electrical behavior aligned with the expected voltage and current response.
