Product Description:

The MAC112B-0-GD-1-B/130-A-1 I01250/SO5 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. As an AC servo motor for analog drive controllers, it converts commanded current into controlled rotary output for positioning, velocity, and continuous-duty tasks on automated production lines, material-handling stages, and packaging equipment. Its frame and flange geometry let machine builders couple the shaft to gearboxes or belt transmissions where precise motion repeatability is required. This layout supports axis applications that need stable response during start-stop cycles and steady operation through long production runs.

The motor contains a blocking brake rated at 45 Nm, allowing the shaft to remain stationary under load when the amplifier is disabled. Thermal energy is removed through natural convection, so unobstructed ambient airflow over the housing is required. Position and speed signals are produced by an incremental encoder feedback device, giving the connected controller fine resolution without digital conversion. The frame follows the motor size 112 classification, which sets the flange pattern, shaft height, and pilot diameter used within the MAC family. For power wiring, a connector on side A is fitted, helping simplify cable routing when the motor is mounted with its rear toward a panel.

The mounting pilot measures 130 mm, providing rigid centering that helps minimize runout when the unit is fastened to precision gear stages. A motor length B lamination stack balances continuous torque against overall depth, which helps the motor fit installations with limited axial space. Listed as a motor for analog drives, it mates with servo amplifiers that issue continuous current commands rather than packet-based profiles. The GD winding code sets the resistance, inductance, and back-EMF values used by the matching amplifier, so the electrical behavior stays consistent with the intended drive range.
