Product Description:

The MAC090B-0-ND-3-C/110-B-1/S005 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for torque and speed control in analog drive systems where precise regulation is required but digital fieldbus interfaces are not present. The motor converts commanded electrical input into controlled rotary motion for positioning and speed-regulated duties. Within an automation cell, it supplies controlled mechanical power to transfer lines, packaging axes, and general-purpose machine tools while remaining compatible with legacy drive amplifiers found in many production plants.

A centering diameter of 110 mm allows the housing to seat accurately in a pilot recess. Heat is removed by natural convection, so external fans or liquid circuits are not required, but installation should still allow free airflow around the housing. Power conductors terminate through a connector on side B, which routes cabling away from the load coupling. Position and velocity signals are provided by a feedback package with tacho feedback and a second shaft end, allowing the motor to supply tachometer signals while supporting auxiliary mounting at the rear of the shaft. This layout can simplify the addition of supplemental feedback hardware when the application requires it.

Holding torque during power loss is supplied by a built-in blocking brake, which helps keep the axis from moving when electrical power is removed. Because the brake is integrated into the motor, a separate external holding device is not required for basic load retention. The control loop uses real-time tachometer voltage rather than digital network communication, making the motor suitable for established drive setups that depend on direct feedback signals. The motor is supplied with a tacho quality that meets standard production tolerances, supporting consistent speed feedback during normal operation. That feedback behavior helps the paired amplifier maintain steady speed correction during routine machine cycles.
