Product Description:

The MAC041B-0-BS-3-E/050-B-1/S006 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for motion axes driven by analog amplifiers, it converts ±10 V commands into controlled torque and speed for pick-and-place gantries, small indexers, and packaging spindles. Its purpose in industrial automation is to supply precise rotary movement while feeding real-time velocity information back to the drive so closed-loop regulation can be maintained during rapid duty cycles.

Its housing and connection arrangement suit compact machine assemblies with limited clearance around the motor body. Heat is removed only through natural convection, so the motor must be installed where ambient airflow is unobstructed and peak current does not exceed thermal limits. The three-phase power leads exit through a connector on side B, allowing the cable bundle to drop parallel to the machine wall and reducing bend stress. For velocity feedback, the rotor carries a tachogenerator that supplies proportional voltage as tacho feedback, eliminating the need for an external encoder in analog drive loops. A standard blocking brake is integrated to clamp the shaft when the amplifier is disabled, preventing load drift in vertical or inertial applications.

The motor has a Motor Size 041 frame and a Motor Length B axial stack, resulting in a compact envelope that fits inside light assembly machinery. A keyed extension on the non-drive side forms the second shaft end, which can accept a hand wheel, fan impeller, or auxiliary transducer without altering primary coupling geometry. As a motor for analog drives, it directly interfaces with legacy controllers that modulate current through analog circuitry, making it suitable for retrofits where digital communication is not required. This arrangement supports applications that need straightforward analog control along with built-in speed feedback and a compact mechanical package.
