Product Description:

The MAC112D-0-FD-1-B/130-A-1/I1250/S05 is a three-phase AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. This unit is intended for analog drive controllers, where it converts commanded current into controllable rotary motion for indexing tables, printing cylinders, and packaging axes. Its flange pattern matches ISO mounting standards, and the power connector is positioned on side A of the housing to keep high-current cables away from feedback wiring in tight control cabinets.

A permanent-magnet blocking brake rated at 45 Nm locks the shaft when the drive is disabled, preventing load back-driving on vertical or suspended mechanisms. Precise mechanical centering is achieved with a 130 mm pilot, which aligns the stator bore with the machine frame and minimizes radial runout. The stator and rotor are designed for continuous operation at 2000 rpm. Because heat must be removed without auxiliary fans, the housing relies on natural convection, so unobstructed airflow around the ribs is required during installation. For analog velocity loops, the integrated DC tacho generator produces 3 V/1000 rpm, giving the drive a linear signal that rises proportionally with shaft speed.

Digital position data supplements the tacho signal through incremental encoder feedback, allowing fine positioning moves with accurate angular tracking. The motor’s active length corresponds to motor length code D, which adds iron stack depth for higher continuous torque while keeping the outside diameter unchanged. Frame designation motor size 112 standardizes key mechanical dimensions, allowing the use of the same gearbox couplings and seal kits found on other MAC units of the same size. Electrical parameters are referenced by winding code FD, and drive software uses this identifier to apply current limits and commutation settings that match the coil resistance and inductance.
