Product Description:

The MAC090C-0-KD-1-B/110-A-2/101000/S013 is a servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for industrial automation tasks, it converts electrical energy into controlled rotary motion. This allows positioning tables, printing modules, and handling axes to maintain repeatable speed and torque under closed-loop control. In this role, the motor responds to command changes from the drive and helps machine axes hold stable motion during repeated start, stop, and speed-change cycles.

Its mechanical interface uses a centering diameter of 110 mm, allowing direct seating into matching machine flanges. Motion is detected through incremental encoder feedback, providing pulse trains that the drive translates into position and speed data for real-time regulation. That feedback helps the control loop correct small load-related deviations while the axis is in motion. The shaft can reach a nominal speed of 1500 rpm, a value chosen to balance torque density with thermal limits during continuous operation. Heat is removed solely by natural convection, so cabinet layouts must maintain unobstructed airflow around the housing. A heavy-duty blocking brake is integrated, and when power is removed it holds the load mechanically to prevent axis creep on vertical or safety-critical stages.

The stator uses winding code KD, which corresponds to the voltage and current ranges expected from the analog drive controller. Power conductors are routed through a connector on side A, allowing the plug to be accessed without disturbing adjacent components. For velocity feedback to legacy loop controllers, the built-in tachogenerator produces 3 V/1000 rpm, giving a linear voltage proportional to shaft speed. The unit is classified as a motor for analog drives, indicating that its feedback signals and commutation conform to voltage-based control platforms rather than fieldbus-oriented systems. Using both feedback devices allows the motor to support control schemes that rely on either pulse-based position data or analog speed signals.
