Product Description:

The MAC090B-0-PD-4-C/110-B-0/WI511LV is an AC servo motor supplied by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for integration with analog drive controllers where continuous position and speed regulation is required. By converting electrical energy into controlled mechanical rotation, the unit drives axes in machine tools, material-handling systems, and automated assembly stations. Its combination of motor output and integrated feedback supports repeatable motion on equipment that depends on stable axis response during normal production cycles.

The motor uses winding designation PD, which corresponds to the resistance and inductance values expected by the associated amplifier. Under rated conditions, the rotor reaches 1500 rpm. This nominal speed is used when selecting gear ratios or ball screw pitches for the driven axis. Shaft alignment to adjoining machine elements is aided by a centering diameter of 110 mm, which supports repeatable face mounting without extra sleeves. Heat is removed through natural convection, so the installation space should allow free airflow around the housing. A built-in tacho generator supplies 3 V/1000 rpm, providing the analog velocity signal needed by legacy drive cards for closed-loop speed control.

The feedback configuration also includes an incremental encoder, so digital position data can be used when a motion controller is present. Power conductors exit through a connector on side B, which helps keep the cable bundle clear of the driven load and simplifies right-angle cable routing. The motor has no mechanical parking brake, so holding torque during power loss must be supplied by the drive or by an external clamp. The unit is a motor for analog drives, which matches earlier MAC servo amplifiers that use voltage-based speed and position loops instead of newer networked interfaces.
