Product Description:

The MAC090A-0-ZD-4-C/110-A-0/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Delivered as a motor for analog drives, it converts command voltages from legacy controller cards into precise shaft motion for automation axes that require stable velocity and position control. This operating style makes the unit suitable for retrofit machinery and established production systems that still rely on analog amplifier architecture. By combining an integrated tachometer and encoder within a sealed housing, the unit supplies the feedback signals a drive needs to close the loop without external sensors, supporting repeatable movement in production equipment and material-handling stations.

The mechanical interface centers on a shoulder diameter of 110 mm, allowing repeatable alignment of the flange to gearboxes or mounting plates. Thermal management relies on natural convection, so no fan or liquid circuit is required. The three-phase winding reaches a rated speed of 1500 rpm, which suits standard 50/60 Hz analog velocity loops. Power conductors are routed through a connector on side A, keeping the opposite end free for feedback cabling. Rotor speed is fed back by a tachogenerator that produces 3 V/1000 rpm, and the signal uses standard tacho quality for proportional speed regulation.

Position information is provided by an incremental encoder with standard mounting, which gives the drive position data without external sensors. The motor uses winding code ZD, which corresponds to the electrical values of the 90-frame stator used in the MAC family. A blocking brake is not present, so load holding during power-off must be supplied by external mechanics or drive torque. This arrangement is appropriate where the axis is secured by the machine transmission or controlled motor torque at standstill.
