Product Description:

The MAC041A-0-FS-2-E/050-B-1 is an AC servo motor produced by Bosch Rexroth Indramat and delivered as part of the MAC AC Servo Motors series. Designed for precisely controlled rotary motion, it interfaces with legacy analogue servo amplifiers to close velocity and position loops in packaging, printing, and material-handling equipment. The motor’s compact frame minimizes installation space while delivering the torque and acceleration required to execute commanded profiles accurately inside automated production cells.

The unit uses a frame that is classified as size A, and its active magnetic stack corresponds to the motor length code 041; together these dimensions define the continuous torque envelope and determine mounting center heights within standard machine frames. Winding designation FS sets the coil resistance and inductance so that a matching analogue drive can supply the required current without saturation. Heat generated in the stator is removed solely by natural convection, making the motor suitable for cabinets or open machines where forced airflow is not available. Rotor position and speed are returned to the controller through integrated tachofeedback, enabling the drive to regulate current and velocity loops without digital encoders.

The power cable exits through a compact connector on side B, allowing the wiring harness to run parallel to the motor body and reducing stress at swivel joints. A mechanically actuated blocking brake is supplied as standard, so vertical axes can hold load torque when the amplifier is disabled. Because the motor is a motor for analog drives, it accepts ±10 V speed commands and delivers proportional shaft rotation without internal bus communications. When paired with factory-specified cables from Bosch Rexroth Indramat, this configuration simplifies commissioning and maintains compatibility with earlier MAC series installations.
