Product Description:

The MAC092A-0-DD-4-C/095-B-0/WI520LV belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is an AC servo unit intended for analog velocity or position loops, turning electrical command voltages into precise rotary motion for tooling spindles, pick-and-place heads, and other industrial automation axes where repeatable speed is critical. Within a multi-axis machine, the motor couples directly to the load through gearboxes or timing belts and can be mounted either horizontally or vertically without special cooling hardware.

Its thermal management relies solely on natural convection, so cabinet airflow planning must allow free circulation around the housing. A 95 mm centering diameter aligns the flange to reference shoulders, keeping radial runout within prescribed limits during high-speed operation. Power conductors terminate through a connector on side B, enabling quick disconnection while keeping the encoder leads isolated on the opposite face. Because the rotor is locked only electromagnetically, the motor is supplied without a blocking brake, so static holding force must be provided externally when the drive is de-energized. Classified as a motor for analog drives, it interfaces with classic Indramat TDM or KDS amplifiers that issue ±10 V commands and receive speed feedback.

Speed and position reporting are delivered through a combined feedback system that offers tacho feedback and an incremental or absolute encoder. For systems that use simple pulse counting, the secondary channel provides an incremental encoder with standard mounting arrangement that fits common 15-pin feedback cables. Voltage ripple in the tacho circuit is held inside the limits of a standard tacho quality rating, avoiding control loop hunting at low speed. These feedback provisions, integrated with the motor's magnetic design, allow the analog controller to perform velocity loops with minimal offset and to execute precise homing cycles without additional sensors.
