Product Description:

The MAC112C-0-HD-1-B/130-B-0/I00625/S005 servo motor is built by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is intended for use with analog drives that demand accurate velocity and torque control in automated equipment. By converting controlled stator current into shaft rotation, the unit forms the primary mechanical output stage for positioning tables, conveyor sections, and coordinated production axes. Its analog-drive design suits machines that use external amplifiers for closed-loop motion control instead of integrated digital drives. This makes it suitable for synchronized axes where steady response and repeatable speed regulation are required during normal machine operation.

The centering diameter measures 130 mm, letting the housing locate precisely in standard mounting flanges. Heat is removed through natural convection, eliminating the need for auxiliary blowers or liquid circuits. Shaft position is reported via incremental encoder feedback, giving the drive phase reference and speed data. Under rated excitation, the rotor reaches a nominal speed of 2000 rpm, while the integrated tacho generator supplies 3 V/1000 rpm so the analog controller can track actual velocity. The motor is supplied without a blocking brake, so static holding torque must be provided by the drive or by external mechanical restraints whenever the axis is idle.

The length classification is C, and the frame corresponds to size 112, balancing torque capacity with installation depth in multi-axis machines. Main power conductors exit through a connector on side B, which helps separate high-current wiring from feedback cabling placed on the opposite face. The separation of power and feedback paths can also simplify cable routing in compact machine layouts. Internal coils follow the HD winding code, matching the electrical characteristics used by legacy MAC-series amplifiers. Because cooling relies solely on ambient airflow, adequate clearance around the casing helps maintain temperature limits. The motor is intended for analog servo systems that use proportional-integral regulation and separate motion control hardware.
