Product Description:

The MAC041A-0-FS-3-E/050-A-1/S001 is an AC servo motor positioned within the MAC AC Servo Motors series and manufactured by Bosch Rexroth Indramat. It converts command signals into controlled rotary motion for industrial positioning tasks such as indexing tables, light gantries, and packaging stations. Through its compact frame and integrated feedback elements, the unit supports precise velocity regulation and accurate shaft positioning required on dynamic automation axes.

Thermal management relies on passive airflow because the motor is cooled by natural convection; this eliminates the need for external blowers and simplifies cabinet layouts in small machinery. The electromagnetic design uses an FS winding, giving voltage and current characteristics matched to legacy Indramat drive electronics. Mechanical holding torque during power loss is maintained by the standard blocking brake, so vertical or suspended loads can stay in place without additional clamps. Position control signals are derived from the internal tachogenerator, and the factory-machined auxiliary shaft supports this sensor in a configuration described as tacho feedback with a second shaft end. Power leads enter through a keyed connector on side A, allowing cable routing parallel to the drive train.

The motor uses compact dimensions suited to pick-and-place gantries. The housing follows the 041 length code, keeping the overall body short for reduced moment load on mounting plates, while the frame classified as size A standardizes the bolt pattern and flange diameter across the series. Because it is a motor for analog drives, speed is established directly from the servo amplifier’s analog output without internal digital processing, which reduces latency in velocity loops. Integration with other Bosch Rexroth controllers is supported by the matched feedback scaling and wiring conventions used by Bosch Rexroth Indramat in multi-axis systems where these legacy analog interfaces remain in service.
