Product Description:

The MAC090C-0-GD-4-C/110-A-2/MR119/S013 is a servo motor manufactured by Bosch Rexroth Indramat and part of the MAC AC Servo Motors series. Designed for closed-loop motion axes, it supplies rotational energy to analog drive controllers that regulate speed and torque in automated machinery such as packaging stations and material handlers. Its mechanical envelope, electrical winding arrangement, and integrated feedback options make it compatible with a wide range of Indramat drive amplifiers used in industrial automation. This type of motor is commonly used where proven analog servo hardware remains part of the control platform.

The motor is supplied with a heavy-duty blocking brake, which applies holding torque during power-off conditions so vertical or suspended loads remain stationary without relying on the drive. A centering pilot of 110 mm aligns the flange precisely on the machine frame and helps reduce radial runout. Heat generated in the stator is dissipated by natural convection, removing the need for external blowers and allowing installation where added cooling hardware is undesirable. Three-phase power leads terminate through a connector on side A, so cable routing can follow a predictable path along the machine. The GD winding code indicates the electrical winding arrangement used for matching voltage and current behavior in the connected drive amplifier.

The feedback stage accepts incremental or absolute encoder feedback, enabling the drive to govern both speed and position without additional sensors. The motor uses standard tacho quality, which helps maintain predictable voltage ripple during low-speed operation. As a motor for analog drives, it interfaces directly with legacy voltage-command amplifiers that rely on ±10 V reference signals. Because the feedback is integrated, the motor can report shaft movement without external transducers mounted on the machine, which supports smooth starts, stops, and speed changes during operation.
