Product Description:

The MAC112D-0-ED-1-B/130-A-0/J625/S005 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a motor for analog drives that supplies continuous rotary motion to positioning tables, gantry axes, and other automation assemblies that require precise velocity control. It integrates with legacy drive amplifiers while maintaining the standard servo motor form factor used in many machine frames. That makes it suitable for retrofit applications where the mechanical interface must stay unchanged while the surrounding machine remains in long-term service.

This model centers on a flange with a 130 mm locating diameter, giving the mounting pilot the stiffness needed for repetitive indexing moves. Shaft speed reaches a nominal 3000 rpm, allowing direct coupling to gearboxes or loads that need moderate to high rotational speed without overspeeding the magnetic circuit. Heat leaves the stator by natural convection, so the enclosure relies on free airflow rather than forced cooling devices. The stator uses winding code ED, which indicates the electrical characteristics chosen for continuous torque balance against current limits. For closed-loop velocity regulation, the embedded tacho generates 3 V/1000 rpm, providing an analog feedback signal that the controller uses for speed correction.

Rotor position is tracked by incremental encoder feedback, enabling digital commutation and fine position interpolation when paired with compatible converters. The encoder signal also helps the drive maintain smooth motion at low speed and during short positioning moves. The frame follows the mechanical envelope designated as 112, ensuring shaft height and bolt pattern compatibility across machines already set up for this size. The motor has no blocking brake, so vertical axes must rely on external clamps or drive torque for holding. Power enters through a connector on side A, orienting the cable toward the drive cabinet and keeping the opposite side free for service access. The unbolded length code D indicates the deeper stator stack used for higher continuous output.
