Product Description:

The MAC041B-0-BS-4-E/050-B-0/WI651LV/S006 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Intended for compact axes in assembly machines and handling equipment, it works with analog motion systems that use continuous reference signals. The motor transforms drive-supplied current into controllable rotary motion that follows analog velocity or position references, providing the mechanical element required to move tooling with repeatable accuracy.

Thermal management relies on natural convection, so enclosure airflow around the aluminum frame is important when continuous duty cycles are expected. The electromagnetic core uses length code 041, indicating a short stator stack that minimizes rotor inertia while still generating rated torque. The motor uses a square flange of size B, allowing direct bolting to gearheads or machine plates without custom adapters. Line power reaches the stator windings through a connector on side B, positioning the cable away from the driven shaft and simplifying routing in tight spaces. Because the unit is supplied with no blocking brake, any vertical load must be secured externally.

Motion feedback is handled by a combined incremental or absolute encoder with tacho feedback, and an auxiliary incremental encoder with standard mounting can supply additional position data through differential signals to legacy controllers. As a motor for analog drives, the MAC041B integrates with voltage-controlled amplifiers that modulate current loops without fieldbus communication. This arrangement supports straightforward retrofit into older automation cells that still rely on analog amplifiers and separate controller feedback inputs. The separate feedback paths also let the drive receive speed-related information while external control hardware monitors position at the same time. That split is useful in machines where the motion amplifier and the supervisory controller do not share a common feedback format.
