Product Description:

The MAC112C-0-HD-4-C/130B-1/AM164SG/S005 is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts command voltages from legacy drive amplifiers into precise rotary motion for automated machinery. Within an installation, the unit supplies the closed-loop torque and speed control required by transfer lines, material-handling stations, and packaging axes, making it suitable for applications that need synchronous motion without digital communication layers.

This model adopts a centering diameter of 130 mm, enabling repeatable flange alignment against gearboxes or mounting plates. Its frame outline follows the MAC size code, where a motor size of 112 balances electromagnetic capacity with footprint. The length designation C increases stack height so the stator can deliver higher continuous torque while keeping inertia moderate. Under rated excitation, the rotor reaches 2000 min⁻¹, a speed well suited for medium-throughput indexing tasks. Heat generated during operation leaves the housing by natural convection, removing the need for auxiliary blowers.

Electrical characteristics are set by the winding code HD, whose resistance and inductance match analog power stages that supply the required current envelope. Position and velocity feedback are provided through a sensor package with tacho feedback, an incremental encoder, or an absolute encoder, allowing the drive to support either simple voltage-based speed loops or high-resolution motion control. The embedded tacho generator outputs 3 V/1000 min⁻¹, giving the controller a proportional voltage reference across the full speed band. Tacho quality is graded as standard, indicating that drift, linearity, and ripple remain within the range expected for general-purpose industrial servo regulation.
