Product Description:

The MAC092B-0-QD-4-C/095-B-0/AM164SG is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it transforms analog current commands into controlled torque for automated positioning, indexing, and light-duty process axes. Its permanent-magnet construction and integrated feedback support precise closed-loop speed and position control. The feedback lets the paired controller correct load-related speed changes during operation, which helps the axis maintain steadier motion during starts, stops, and short indexing moves.

Mechanically, a centering diameter of 95 mm aligns the motor housing with mating flanges and helps limit radial misalignment that could stress the bearings. Heat is removed through natural convection, so the frame must remain exposed to ambient airflow. Electrical power enters through a power connector on side B, which helps when the opposite face is inaccessible. Because the unit has no blocking brake, static load retention must be provided by the drive or an external clamp when power is off. Feedback for speed regulation is classified as standard tacho quality, which is suitable for general motion tasks that do not require extremely fine positioning. This layout also supports cleaner cable routing in compact machine spaces.

Position reporting depends on an integrated absolute encoder, eliminating homing cycles after each power-up. The motor also includes a tachofeedback incremental or absolute encoder channel, so analog drives can use either velocity-oriented or position-oriented control. Because position data is available immediately after startup, the axis can return to commanded motion without a separate reference run. The dual-feedback arrangement keeps wiring simpler across similar installations and supports consistent response in multi-axis systems.
