Product Description:

The MAC090B-0-PD-4-C/110-A-2/WI524LV/S013 is an AC servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. Built for analog drives, it supplies controlled torque and speed to legacy servo amplifiers used in indexing tables, pick-and-place axes, and packaging spindles. In a closed-loop motion system, this unit converts electrical command signals into precise rotary motion so tooling and material can reach commanded positions with repeatable accuracy. Its layout supports applications that need dependable motion control without adding separate external feedback hardware for basic speed regulation.

At a nominal speed of 1500 rpm, the rotor operates at a stable point that balances torque production with thermal limits. A 110 mm centering diameter guides alignment at the mounting face, allowing direct coupling to gearboxes or flanges without added alignment pieces. Winding code PD indicates the coil pitch and resistance used by the motor, allowing the drive to deliver current without saturation during routine duty cycles. The tachogenerator produces 3 V/1000 rpm, creating an analog speed signal that the controller can scale in a linear manner. Power conductors terminate through a connector on side A, which helps when cable access is available from only one face of the machine or cabinet.

A heavy-duty blocking brake is integrated to hold the shaft during power-off conditions, which helps prevent load drift on vertical or indexing axes. Heat is removed by natural convection, so the motor depends on free air circulation around the housing instead of forced airflow. For velocity and position supervision, the motor uses tacho feedback together with an incremental encoder with standard mounting aligned to the end bell. The feedback arrangement supports stable monitoring during general machine operation and keeps the signal path straightforward for compatible analog control systems. The tacho signal has standard tacho quality, which is suitable for general-purpose speed regulation in material-handling and assembly lines.
