MAC090C-1-GD-4-C/110-A-1/WI515LX5/S005

The MAC090C-1-GD-4-C/110-A-1/WI515LX5/S005 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. The unit serves as a rotary actuator in industrial automation, delivering controlled torque and speed to axes driven by analogue servo amplifiers. Its design suits positioning, contouring, and cyclic handling tasks where closed-loop control and rapid response are required. It integrates mechanical and electrical interfaces that align with the manufacturer’s legacy MAC platform, enabling straightforward replacement in existing drive chains and consistent performance across multiple machine generations.

Mechanical integration starts with a centering flange that has a 110 mm pilot diameter, allowing repeatable shaft alignment against gearboxes or mounting plates. The rotor uses a GD winding, which determines resistance and inductance values matched to the companion drive stage. Heat generated by copper losses is removed through axial surface cooling, and an external blower rated at AC 230 V supplies the required airflow. A standard blocking brake is fitted so the shaft can hold position when power is removed, a frequent requirement on vertical or safety-critical axes. These features combine to maintain thermal stability, positional security, and electrical compatibility within the specified speed range.

Signal feedback is provided through a tachofeedback incremental or absolute encoder, complemented by a standard tacho quality rating that meets general motion accuracy needs. Position information is further available from a incremental encoder with standard mounting, giving the controller high-resolution pulse streams for velocity and displacement regulation. Power cabling enters through a connector to side A, simplifying routing inside cabinets that mount the motor with its cable exit facing upward. Because the unit is defined as a motor for analogue drives, it interfaces directly with legacy current-controlled amplifiers without requiring digital communication layers. Together, these interface attributes streamline commissioning and keep retrofit effort low.
