Product Description:

Bosch Rexroth Indramat produces the MAC112D-0-ED-4-C/180-A-0/WI518LV/S039 as part of the MAC AC Servo Motors series. This motor for analog drives converts drive-controller current into synchronized mechanical rotation for positioning, indexing, and speed-control tasks within automated machinery. It is suited to motion axes that need stable rotary output and feedback-based control during repeated operating cycles. Its feedback arrangement allows the connected controller to monitor motion continuously while the axis is running.

The unit centers on a 180 mm pilot diameter to align precisely with gearbox or machine frames, and frame code 112 indicates the stator cross-section used for this motor size. Motor length code D extends the active iron, giving the winding additional slot area for higher continuous power. Rated mechanical speed is 3000 min⁻¹, allowing the shaft to match typical servo-drive output frequencies without overspeed. Heat is removed by natural convection, so the housing needs unobstructed airflow rather than forced cooling. The power conductors exit through a connector on side A, which helps simplify cable routing when the drive sits to the left of the motor. The motor is supplied without a blocking brake, so external holding methods are needed when power is removed.

Winding code ED identifies the stator wire gauge and turns associated with the resistance and current constants expected by analog drives. Position verification comes from an incremental encoder with standard mounting, consistent with the feedback arrangement that also supports tacho feedback. The tachogenerator produces 3 V/1000 min⁻¹, and its standard quality rating provides adequate linearity for general motion loops. The incremental encoder supplies position pulses while the tacho channel supports stable speed regulation through the matched drive. This combination supports applications that need coordinated position tracking and steady velocity control from the same motor package.
