Product Description:

The MAC090B-0-PD-4-C/110-B-1/WI518LV is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied as part of the MAC AC Servo Motors series. In analog drive environments, it transforms command voltages into precise rotary motion and provides closed-loop force and speed control for machining centers, assembly lines, and handling modules. This operating role supports repeatable motion on axes that must start, stop, and hold position with minimal deviation during normal production. It is intended for machinery that depends on smooth torque response and steady low-speed behavior during repeated motion cycles.

Mechanically, the motor mounts against a 110 mm centering diameter and uses natural convection to remove heat, so no external blower is needed. The motor uses winding code PD, and its rated shaft speed is 1500 rpm, which supports regulated current flow during normal operation. A standard blocking brake holds the load when power is removed, helping prevent uncommanded back-drive on vertical or suspended axes. Tachometer quality is standard, and the feedback electronics can work with either incremental or absolute feedback. This gives the paired amplifier flexibility when a machine requires different feedback arrangements for speed or position control.

Electrical terminations are routed through a connector on side B, which can simplify cabinet layouts where service space is limited. Position feedback is derived from an incremental encoder with standard mounting, and the integrated tacho generator produces a 3 V/1000 rpm tacho voltage that the analog drive card uses for velocity regulation. The unit is a motor for analog drives, so it interfaces directly with voltage-controlled amplifiers rather than digital fieldbus modules. This arrangement supports stable speed control on machines that rely on continuous analog feedback during positioning and steady-state operation. The side-mounted connection also helps keep cable routing clear of adjacent machine components when the motor is installed in compact axis groups.
