Product Description:

The MAC112D-0-ED-4-C/130-A-2/WI520LX/S018 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for use with analog drive controllers, it transforms current commands into controlled torque and speed to position machinery parts accurately. The frame corresponds to motor size 112 with length code D, a combination often selected for medium-power axes in packaging lines, material-handling gantries, and indexing tables where precise yet economical motion control is required. In systems that use analog command signals, this arrangement lets the paired controller regulate acceleration, steady running, and stopping with predictable motor response.

The motor contains a heavy-duty blocking brake that holds the shaft statically at up to 60 Nm, securing vertical or suspended loads whenever power is removed. Thermal energy is dissipated by natural convection, so the housing needs no external fan assemblies. Because cooling is passive, the motor can be installed where added airflow hardware would be impractical. When energized at rated conditions, the rotor can reach 3000 rpm, matching common gearbox ratios found on 50/60 Hz production equipment. Accurate mounting is assisted by a 130 mm centering diameter on the front flange, and this pilot aligns the motor coaxially with couplings to limit radial runout.

Input power is delivered through a connector on side A, simplifying cable routing inside enclosures and keeping feedback connectors accessible. Shaft angle is measured by an incremental encoder with standard mounting, while the built-in tacho generator outputs 3 V/1000 rpm for analog speed loops; together they support fine velocity regulation and quick fault response. The separate feedback channels allow the controller to track motion continuously during speed changes and holding periods without relying on external sensing devices. The stator uses winding designation ED, which indicates the resistance, inductance, and thermal behavior expected by the matching drive during acceleration and holding phases.
