Product Description:

The MAC090A-0-RD-3-C/110-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It interfaces with analog servo amplifiers to translate commanded current into controlled torque and speed for axes on machine tools, material handlers, and packaging lines. By delivering rapid acceleration and accurate holding capability, the motor serves as the mechanical actuator that positions loads, indexes spindles, or drives transport systems in automated production environments where repeatable motion is critical. Its operating concept fits retrofit and existing control platforms that still rely on voltage-based drive commands rather than newer networked motion systems. That makes it suitable for packaging equipment, transfer stations, and general automation tasks that depend on repeatable starts, stops, and speed changes.

Within this model, heat is removed by natural convection, so installation does not require a blower or liquid manifold and cabinet airflow remains uncomplicated. Electrical power reaches the stator through a connector mounted on side A, allowing the cable route to align with drive cabinets placed adjacent to the motor face. The flange provides a centering seat of 110 mm, which aligns the housing concentrically with the driven machine element and helps control radial runout during operation. A standard blocking brake is integrated to secure the shaft when the amplifier is disabled, preventing unwanted back-drive on vertically loaded or high-inertia axes. Because cooling is passive, there is no separate fan assembly to route or power around the motor body.

For velocity feedback, the unit incorporates tacho feedback, and the design also offers a second shaft end so users can attach an auxiliary encoder, handwheel, or mechanical sensor without altering the main coupling. Classified as a motor for analog drives, it exchanges velocity and command information through continuous voltage levels rather than digital buses, matching legacy control hardware still common in many factories. Position accuracy is governed by standard tacho quality, providing linearity that is sufficient for general positioning, indexing, and feed rate regulation without the submicron resolution demanded by ultra-precision machining lines. This arrangement supports stable speed feedback and gives the drive system a straightforward way to monitor motion during normal machine operation.
