Product Description:

The MAC041B-0-BS-4-E/050-A-0/WI668LV/S001 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a compact AC servo motor engineered for analog drive controllers that need finely regulated speed and position in automated machinery. By coupling to belt drives, small gearboxes, or direct-drive spindles, the unit translates electrical command signals into stable rotational motion that can be synchronized with process demands inside packaging stations, pick-and-place modules, or light material-handling axes.

This model sheds heat through natural convection, so no external blower or liquid circuit is required. Dimensional classification starts with the designation of motor length 041, which indicates the axial stack height, and the frame code motor size B, which identifies the stator diameter used for torque generation. Power conductors leave the housing through a connector on side A. Locating the connector on the drive-end face simplifies cable routing when the motor is installed against a rear machine panel, and it keeps high-voltage leads separate from feedback wiring.

Because there is no blocking brake, any load must be held by external clamping or continuous drive torque during power-off conditions. The feedback interface uses tacho feedback with an incremental or absolute encoder, allowing the associated drive to use velocity-loop sensing or full position monitoring as needed. For systems that standardize on incremental signaling, the shaft carries an incremental encoder with standard mounting, ensuring mechanical interchangeability with earlier MAC motors. The product is cataloged as a motor for analog drives, so its signal levels and power connectors match legacy analog amplifiers from the same vendor. Manufactured by Bosch Rexroth Indramat, the unit integrates into existing MAC motor brackets without changes to bolt-circle or pilot dimensions.
