Product Description:

The MAC090B-0-PD-4-C/130-A-0/WI520LV/S003 is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is designed for use with analog drive amplifiers to deliver controlled rotary motion in automated machinery. The motor converts commanded drive currents into precise shaft torque for positioning, indexing, and speed regulation tasks in assembly lines, packaging units, and material handling stations.

The winding set uses code PD, which indicates the coil resistance and inductance pair required by the matching analog drive for stable operation. Under rated excitation, the rotor reaches 1500 rpm; this nominal speed provides the velocity reference for motion sequences that rely on synchronous analog control loops. A built-in tacho generator outputs 3 V/1000 rpm, giving the drive a proportional speed signal for closed-loop regulation without a dedicated digital encoder interface. Heat produced in the stator is removed by natural convection, so cabinet layouts must allow free air circulation around the housing to keep winding temperature within limits. The machined mounting face has a 130 mm centering diameter that aligns the motor concentrically with gearboxes or direct-drive load flanges, which helps minimize radial misalignment.

Shaft position is monitored through an incremental encoder mounted in the standard interface, while the tacho channel provides an additional speed signal for the connected drive. Power conductors exit through a connector on side A, which simplifies cable routing in machines where the drive cabinet is located on that side of the axis. Because there is no blocking brake, vertical or overhung loads must be secured by external mechanisms when power is off. Classified as a motor for analog drives, the unit integrates into legacy controller architectures that depend on analog velocity and torque commands rather than fieldbus communication.
