Product Description:

The MAC093B-0-GS-4C-11-0-B-0-WI520-S01 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it translates current commands from legacy amplifiers into controlled torque and speed for machining centers, printing lines, and material-handling stations. Its design supports installations that use analog velocity and torque loops, allowing the motor to operate with compatible drive equipment. Integrated motor feedback gives the connected amplifier the information needed to regulate shaft motion as the mechanical load changes.

Heat generated during operation is released through natural convection, so no active fan is required and airflow around the enclosure remains uncomplicated. The motor has a nominal speed of 4000 rpm, providing sufficient speed for rapid traverse movements and other high-speed axis functions. Its frame size of 093 provides a moderate mechanical envelope suitable for compatible gearboxes and machine mounting arrangements. The GS winding code indicates the electrical winding arrangement used with compatible analog regulators. Power conductors exit through a connector on side B, simplifying cable routing when the shaft faces the interior of the machine. This connector position can also help keep the power cable away from nearby tooling and moving machine components.

The motor is supplied without a blocking brake, so an external clamp or drive-generated torque must secure the load when required. Its B length index indicates an extended magnetic stack that supports higher continuous torque within the same frame size. The motor has tacho feedback with an incremental or absolute encoder, providing velocity information for the analog control loop and position data for motion monitoring. Its primary position device is an incremental encoder with standard mounting, which supports connection to conventional drive cards designed for this feedback type. The encoder arrangement allows the controller to track shaft movement and correct deviations while the axis accelerates, runs at speed, or decelerates. Proper cable routing and secure connector engagement help preserve the quality of the feedback signals in electrically noisy industrial machinery.
