Product Description:

The MAC041A-0-FS-4-E/050-B-0/WI668LV is a brushless AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a compact actuator for analog drive systems, it converts electrical command signals into controlled rotary motion for pick-and-place gantries, indexing tables, and light-duty packaging axes. By combining permanent-magnet excitation with integrated feedback, the unit supports tight velocity control and repeatable positioning cycles while keeping enclosure space and wiring complexity low in automated production equipment.

The winding set is identified by the FS code, indicating the copper fill and magnetic characteristics selected for the motor’s torque constant. A frame size of 041 pairs with the A length class, yielding a slender body that fits compact multi-axis arrangements without adapter plates. Internally generated heat leaves the housing through natural convection, so the installation must provide unobstructed airflow around the ribbed stator shell. Power conductors terminate at a connector on side B, keeping the power lead clear of the load end and separated from the feedback cabling. This cable orientation also supports orderly routing when several motors are installed close together in a machine.

The standard sensor package supports tacho feedback with an incremental or absolute encoder. This unit includes an incremental encoder with standard mounting that is aligned with the motor shaft. The continuous position signal allows an analog controller to issue velocity or torque commands with minimal phase lag. As a motor for analog drives, the unit is compatible with suitable voltage-mode or current-mode amplifiers that do not require fieldbus communication. Because the motor has no blocking brake, stationary holding force must be supplied electrically by the drive or mechanically through an external locking device.
