The MAC112D-0-ED-1B/130-A-1/J1250/S005 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is intended for closed-loop motion axes in industrial automation, supplying rotary power while allowing precise speed and position regulation through an external drive controller.
This model removes heat by natural convection, so no blower or liquid circuit is required as long as cabinet airflow is adequate. Rotor position is reported through incremental encoder feedback, delivering discrete pulses that a drive converts to velocity or incremental position data. The construction falls under motor size 112, indicating a 112 mm stator frame that balances torque density against envelope constraints common on medium-duty machines. A nominal speed of 3000 min⁻¹ defines its rated mechanical output point when fed with the corresponding drive current and voltage. Inside the stator, winding code ED specifies the turns ratio and conductor gauge; this matches the motor to drives that can supply the correct peak and continuous current without magnetic saturation.
The active stack corresponds to motor length D, giving a longer iron core than shorter variants in the series and therefore higher continuous torque at the same frame diameter. Designed as a motor for analogue drives, it interfaces with controllers that use ±10 V velocity or torque commands instead of fully digital fieldbus links. Within Bosch Rexroth Indramat’s catalog, the MAC AC Servo Motors line provides interchangeable mechanical options while retaining identical electrical feedback standards, allowing the same drive family to scale power across multiple axes. The manufacturing quality and global support network offered by Bosch Rexroth Indramat simplify lifecycle maintenance and retrofit planning for end users.
