Product Description:

The MAC041A-0-FS-4-E/050-A-0/WI668LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for closed-loop motion tasks, the unit converts electrical command signals from an analog drive into controlled shaft torque and speed, enabling precise positioning of light machinery axes, pick-and-place heads, or compact gantry slides commonly found in automated production lines. Its magnetic circuit and rotor inertia are scaled for quick acceleration while maintaining the velocity regulation demanded by assembly and handling equipment.

The motor employs a winding coded FS, a designation that sets the voltage constant and permissible current so the drive can predict torque over its full speed range. Its active stack follows the 041 length class, giving a shorter magnetic path that keeps overall mass low yet supports continuous operation at rated load. Frame designation A defines the square flange and shaft height, simplifying direct attachment to gearboxes or couplings built for this metric envelope. Heat is removed solely through natural convection; the housing relies on surface area and ambient airflow, so no external blower or liquid circuit is needed. Rotor position is detected by an incremental encoder with standard mounting, providing evenly spaced pulses that the controller interprets for velocity feedback and homing routines.

Power conductors terminate through a connector to side A, keeping cable entry on the same face as the mounting bolts and reducing bend radius inside tight cabinet spaces. For applications that demand higher resolution or redundancy, the feedback wiring supports a tachofeedback incremental or absolute encoder, allowing the installer to select the required sensor without mechanical changes. There is no blocking brake, so load holding during power-off must be handled by external clamping devices or drive torque. Because it is a motor for analogue drives, command interfaces are voltage or current references rather than digital fieldbus, ensuring compatibility with legacy Rexroth transducers and amplifier cards still prevalent in established equipment.
