Product Description:

The MAC112B-0-LD-2HC/180-B-0/S003 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts commanded current into rotary motion for positioning axes, regulating speed, and supporting repeatable movement in production equipment. The motor is intended for systems that use conventional analog amplifiers instead of fully digital drive controllers, so it fits legacy machine platforms that still require stable torque response, smooth acceleration, and consistent velocity control during frequent starts, stops, and load changes.

The mechanical interface uses a centering diameter of 180 mm, which helps the housing seat accurately against a matching pilot. Frame size 112 identifies the flange pattern and shaft height used for this MAC configuration. Cooling is handled by natural convection, so the housing must have free surrounding airflow and does not rely on an external fan during normal operation. Under rated conditions, the motor reaches a nominal speed of 2000 rpm, which suits many general-purpose axis applications. Power conductors terminate through a connector on side B, which can simplify cable routing when the driven load or gearbox is positioned on the opposite side of the installation.

Velocity feedback is provided by integrated tacho feedback, which supplies a calibrated signal of 1.5 V/1000 rpm for direct use with analog drive cards. The tacho assembly is graded as standard, making it suitable for general-purpose motion control where stable speed information is required. Electrical characteristics correspond to winding code LD, so the matching amplifier must use the voltage and current values associated with that winding. This arrangement lets the drive process speed information directly without a separate digital feedback converter. The motor does not include a blocking brake, so any vertical axis or suspended load must be held by external braking hardware or by continuous holding torque from the drive.
