Product Description:

Bosch Rexroth Indramat manufactures the MAC112D-0-ED-4-0/130-A-0/WI520LX/S005, an AC servo motor in the MAC AC Servo Motors series. The design is intended for analog drive systems that require accurate torque and speed regulation at the controller level. In automated machine tools, packaging lines, and handling stations, this motor converts electrical input into controlled rotary motion and supports repeatable axis movement during positioning and speed-controlled operation. Its operating concept suits applications where the drive amplifier closes the control loop by using motor feedback rather than electronics mounted separately on the axis.

The mechanical interface begins with a centering flange diameter of 130 mm, which helps keep the motor concentric with the driven machine frame during installation. Nominal shaft speed reaches 3000 rpm, a range suited to medium-inertia loads supervised by velocity loops and continuous production duty. Thermal energy at that operating point is removed by natural convection, so no external blower or liquid circuit is required. The winding code is ED, which corresponds to the resistance and inductance values used by MAC analog drives. Power conductors exit through a connector on side A, allowing orderly cable routing in enclosures where access space is limited. A blocking brake is not present, so static holding force must be supplied by external mechanics when the axis is at a standstill.

With frame size 112 and length code D, the housing provides the active iron needed for its torque class without excessive inertia. Position information is generated by an incremental encoder mounted in the standard rear location, and an integrated tacho coil delivers 3 V/1000 rpm for direct speed feedback when the drive scheme requires it. Shaft torque is transmitted through a DIN 6885 keyway, enabling coupling with standardized hubs and keyed transmission elements. The keyed shaft supports direct torque transfer to couplings, pulleys, and gearbox inputs. The encoder and tacho signals allow the connected drive to monitor rotor motion during both steady-speed operation and commanded position changes.
