Product Description:

The MAC112C-1-HD-3-C/130-A-1/S005 is a servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is configured for analog drives and is commonly used on positioning or speed-controlled axes in legacy automation systems. In automated machinery, the unit converts command voltages into rotary motion that is monitored through integrated tacho feedback for closed-loop control. This arrangement lets the drive respond to speed changes without requiring a separate external feedback device.

The 112 frame with a C-length housing provides space for the stator, and winding code HD identifies the electrical version used with matching drive amplifiers. A centering diameter of 130 mm aligns the flange to the mounting surface for repeatable shaft concentricity. Thermal energy is removed through axial surface cooling, and an external blower rated at AC 230 V moves air along the ribs to maintain motor temperature. Under rated conditions, the rotor reaches a nominal speed of 2000 rpm, which supports stable base-speed operation across geared and direct-drive axis layouts. Power leads use a dedicated connector, while the feedback connection is placed on the opposite end of the housing to keep the cable paths separated.

A blocking brake is supplied as standard and delivers a holding torque of 45 Nm, so vertical or suspended loads can remain stationary when drive power is removed. The tachogenerator mounted on the second shaft end produces 3 V/1000 rpm, giving the analog drive a continuous speed signal during operation. For wiring convenience, the three-phase power enters through a connector on side A, which keeps the brake and tacho leads separate from the main supply path. Separate routing of these circuits can help reduce clutter around the motor connection area.
