Product Description:

The MAC090A-0-RD-4-C/110-A-1/W1525LV/S001 is a servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for mid-frame rotary axes in automated machinery, the unit converts commanded drive current into controlled torque and speed so position loops remain accurate under changing load conditions. In closed-loop motion systems, the motor receives current setpoints, generates magnetic force, and delivers repeatable shaft output for transfer lines, packaging modules, and material-handling stages that must hold consistent motion during continuous production.

Mechanical alignment uses a centering diameter of 110 mm, which matches standard machine flanges and helps maintain accurate mounting during assembly. Heat generated in the stator is removed by natural convection, so the motor relies on passive cooling without external blowers as long as airflow around the housing remains unobstructed. Power enters through a connector on side A, allowing cables to route parallel to the motor housing and stay clear of adjacent axes. For velocity and position feedback, the unit uses tacho feedback together with an incremental encoder, allowing the drive to process a fine pulse train while also supporting traditional tachometer-based control loops.

An additional feedback path is provided by an absolute encoder, enabling single-turn position reporting without a homing routine after power-up. The device is a motor for analog drives, so its insulation system and signal wiring are arranged for use with voltage-controlled amplifiers rather than digital fieldbus interfaces. Motion retention during power loss is handled by a standard blocking brake that clamps the shaft when release voltage is removed. The motor also has a standard tacho quality rating, indicating tachometer output linearity and low ripple suitable for precise speed regulation across the operating range.
