Product Description:

The MAC112D-0-ED-4-C/130-1-0/WI511LV servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is a motor for analog drives that converts command voltages from legacy drive amplifiers into precise rotary motion for automated machinery such as packaging axes and transfer stations. In this role, the motor supplies continuous torque while working with position or speed feedback devices so the connected controller can close the motion loop with minimal lag.

With a frame size of 112, the unit mounts through a centering bore that measures 130 mm, allowing quick alignment to gearboxes or machine plates. The laminated stator uses winding code ED, which indicates the copper fill, resistance, and inductance values selected for medium current draw at rated operating conditions. Under nominal excitation, the rotor reaches 3000 rpm, a speed that suits belt-driven and direct-drive tasks that require fast indexing. Thermal energy is released by natural convection, so the housing fins must remain exposed to ambient air rather than enclosed behind ducted coolant. The specified motor length is D, giving a balance between electromagnetic power density and overall inertia that helps support stable tuning in analog velocity loops.

The MAC112D variant is delivered without a blocking brake, so static holding torque must come from external clamps or drive current. A two-pole tachogenerator is included with a quality grade of Standard, and its output value of 3 V/1000 rpm supplies speed feedback to analog regulators. For more advanced platforms, the winding end supports tacho feedback, incremental, or absolute encoder options, while the main shaft includes an incremental encoder with standard mounting for position supervision. This feedback arrangement allows the motor to work with both older control systems and newer closed-loop platforms.
