Product Description:

The MAC112D-0-FD-3-C/130-A-2/S018 is a servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts electrical power from coordinated drive controllers into controlled shaft rotation for positioning or velocity loops on industrial machinery. It is used on mid-frame rotary axes that need consistent torque and stable speed regulation during repetitive machine cycles. Its mechanical interface follows IEC mounting conventions for standard installation, and a factory-fitted second shaft end supports external feedback devices or manual handwheels.

As a size code 112 unit, the motor has a stator cross-section suited to medium-inertia loads, while the length class D adds extra active stack length for higher continuous output. The winding code FD corresponds to copper fill, resistance, and inductance values matched to analog drives that operate at standard DC bus voltages. Accurate alignment on the machine frame is achieved through a centering collar measuring 130 mm. The keyed shaft can reach a nominal speed of 2000 rpm when rated voltage and frequency are supplied, and the power connectors are routed on side A of the end bell to keep cable bends short inside compact cabinets.

The motor is equipped with a heavy-duty blocking brake that provides 60 Nm of static holding torque to secure vertical or indexing loads once the drive is disabled. Heat generated by the stator is dissipated through natural convection, eliminating the need for forced-air accessories and allowing installation in sealed enclosures. The built-in tachogenerator delivers 3 V/1000 rpm for velocity feedback and meets the standard tacho quality classification. This arrangement lets the connected drive monitor speed without a separate external sensor, and the tacho and brake conductors share the same multi-pin motor connector.
