Product Description:

The MAC090C-0-GD-3-C/130-A-1/S012 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended to deliver reliable closed-loop speed and torque control in automated machinery that still employs analog command interfaces. By converting voltage references into mechanical rotation, the unit forms the actuator side of packaging lines, material-handling axes, and other precision motion stages. That makes it suitable for retrofit installations where an existing analog drive must remain in service. Stable motor response is also important for maintaining axis synchronization during speed changes and short positioning moves.

The mechanical interface centers on a 130 mm pilot diameter, which aligns the stator housing to gearboxes or mounting flanges and helps maintain shaft concentricity. Heat is removed exclusively through natural convection, so adequate airflow around the frame is needed when duty cycles rise because no fan or liquid circuit supplements the dissipation path. The GD winding code identifies the internal copper distribution and impedance used for this size class. Motion can be held at standstill because a standard blocking brake is fitted; this spring-applied device clamps the rotor when power is removed to keep vertical or suspended loads from drifting.

The signal chain relies on tacho feedback with a second shaft end, so the drive receives a proportional voltage that reflects real-time speed while the auxiliary end permits coupling to external encoder hardware if higher resolution is required. The second shaft end can also support accessory coupling where a downstream device needs speed-related motion taken directly from the rotor. Power conductors enter through a connector on side A, permitting straight routing inside cabinets positioned to the left of the motor body. As a motor for analog drives, it integrates into legacy controller racks without digital protocols. The standard tacho quality level supports typical velocity loops used in general automation equipment.
