Product Description:

The MAC112C-0-HD-2-C/180-A-1/S03 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts velocity or torque reference signals into regulated rotary motion for packaging, printing, and material-handling equipment. The HD winding set provides the electrical characteristics required by a compatible drive amplifier. A built-in blocking brake holds the connected load when motor power is removed, while standard-quality speed feedback supports moderately precise motion control. This arrangement allows the drive to correct speed deviations caused by changing mechanical loads during operation.

The brake provides a mechanical holding torque of 45 Nm, allowing vertical or overhung axes to remain stationary without an external clamp. A centering collar with a diameter of 180 mm aligns the motor flange with a gearbox or machine mounting surface. Heat is removed through natural convection, so the installation must provide adequate open space around the housing for unrestricted airflow. The motor includes tachometer feedback, which generates an analog signal proportional to shaft speed for processing by the connected drive. The rotor has a nominal speed of 2000 rpm, providing a balance of sustained torque and moderate inertia for continuous-duty applications. The standard brake configuration supports load retention during shutdowns and controlled stops.

The motor has a housing length code of C, which indicates the axial body length used for this model. Its frame size is 112, providing the physical envelope required for mounting and load connection. Power conductors terminate at a connector on side A, allowing cables to be routed from that side of the housing without crossing the motor body. The integrated tachogenerator produces 3 V/1000 rpm, which is suitable for the input range of compatible legacy analog velocity amplifiers. Its proportional output allows the amplifier to compare actual shaft speed with the command signal and adjust motor current accordingly. The flange, centering collar, and connector orientation should be considered when arranging the motor near adjacent machine components.
