Product Description:

The MAC063A-0-ES-3-C/095-B-0 is a rotary servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it serves as the torque-generating element in position or velocity control loops on machine tools, packaging lines, and material-handling stations. When paired with a compatible drive controller, this motor converts voltage commands into controlled shaft motion, supporting precise automation tasks that require repeatable acceleration and accurate speed tracking.

The frame uses size code 063, and its centering diameter measures 95 mm, allowing direct seating in matching machine flanges without extra bushings. Heat is removed by natural convection, so airflow around the housing must remain unobstructed to sustain rated output. At its nominal speed of 3500 rpm, the motor delivers continuous rotation suited to medium-inertia loads. The motor has no blocking brake, so any load-holding requirement must be met by an external brake or by drive torque alone. The motor uses length index A, which keeps the stack height short and helps reduce mass and moment of inertia during rapid start-stop motion.

Power conductors terminate on a connector on side B, simplifying cable routing when the shaft points toward the operator side of a machine. Position sensing and speed feedback are provided through tacho feedback and a second shaft end, allowing analog velocity loops and the attachment of user-supplied encoders. The tacho generates 1.5 V/1000 rpm, which gives the drive a proportional signal for real-time speed comparison. Winding designation ES indicates the resistance and inductance values used by low-voltage analog amplifiers. Tacho quality is standard for this series, and the electrical arrangement supports stable operation across the motor’s normal load range.
