Product Description:

The MAC090A-0-RD-4-C/130-A-0/WI520LV/S011 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. This model is intended for use with analog drive amplifiers, where commanded current directly establishes torque. In automated machinery, it provides closed-loop rotary motion for axes that need repeatable positioning and moderate dynamic response, such as feed tables, material-handling gantries, or auxiliary packaging drives. Its integrated feedback interface allows the connected controller to monitor speed and position for continuous correction during operation. That arrangement supports controlled acceleration and deceleration in machines that still rely on analog servo architecture.

The motor is supplied with no holding brake, so load retention during power-off must be handled externally. Accurate mechanical alignment is assisted by a centering pilot of 130 mm, which fits standard flange patterns and helps minimize radial runout between the housing and the machine frame. Heat generated by stator losses is dissipated through natural convection, so airflow around the casing must remain unobstructed to keep temperature within rated limits. Electrical power reaches the stator windings through a connector on side A, which can simplify cable routing in compact cabinets. On axes that must stay fixed after shutdown, a separate holding device or external brake is required.

For motion feedback, the unit supports tachofeedback with incremental or absolute encoder signals, letting legacy analog drives read velocity from a tachometer while modern controllers can derive position from encoder pulses. Its designated application class is motor for analog drives, meaning command inputs are processed as continuous voltages rather than digital networks. The tachogenerator is built to standard quality, providing sufficient ripple control for general industrial duty cycles. Position reporting relies on an incremental encoder with standard mounting, so the feedback device follows a conventional mechanical arrangement. This combination provides speed and position data to the connected controller during operation, and it can support both speed regulation and pulse-based position tracking in mixed-control installations.
