Product Description:

The MAC041B-0-BS-4-E/050-A-0/WI671LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, it translates ±10 V control signals into tightly regulated torque and velocity. Within automated assembly cells, palletizers, or light-duty gantry axes, the motor provides rotary actuation that allows tooling to index, payloads to shift, and mechanical stages to synchronize with repeatable accuracy. Its compact envelope makes it suitable for installation where space is limited while still supporting the dynamic response expected in modern automation. This also makes the unit a practical fit for small transfer mechanisms and packaging stations that need repeatable rotary motion without a large motor housing.

Its stator stack length is classified as 041, which keeps the rotating mass low and supports quick acceleration. The motor uses a 55 mm square flange for mounting to lightweight gearboxes or belt pulleys. Heat generated in the windings dissipates through natural convection, eliminating the need for an external fan. Power conductors exit through a keyed circular connector on side A, letting cables run parallel to the machine wall and helping avoid sharp bends. Combined tacho feedback and encoder interfaces supply velocity and position data to the analog controller for closed-loop regulation.

The motor is delivered without a blocking brake, removing the mass and cabling associated with a holding device. Signals from the incremental encoder work with 1 Vpp or TTL receivers to confirm shaft angle during motion control. The feedback arrangement allows the drive to monitor speed and position during operation, which supports stable regulation on analog axes. Connector layout and feedback routing allow straightforward pairing with legacy RECO amplifiers in existing installations. If the axis must remain fixed after shutdown, holding force must be provided by the drive or by external mechanical hardware.
