Product Description:

The MAC041B-0-BS-2-E/050-A-1 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is intended for analog-controlled positioning axes found in pick-and-place stations, compact conveyors, and automated assembly tooling. By translating command voltages from a drive into rotational motion and precise torque, the unit works as a closed-loop actuator in industrial automation where response time and repeatability are important. The compact housing and sealed stator support installation in confined machine spaces while maintaining stable thermal behavior during continuous operation. Its feedback and brake arrangement also suit axes that must stop accurately and remain in position during pauses between cycles.

Cooling is handled by natural convection, so heat dissipates through the housing surface without auxiliary blowers. Rotor speed is reported by a tachogenerator, reflected in the feedback arrangement described as with tacho feedback; this analog signal supports classical velocity loops used by older drive controllers. The tacho signal gives the amplifier a direct speed reference without requiring a digital encoder interface. Dimensional coding identifies the stator stack as 041 and the frame size as B, a combination that keeps inertia low for light handling duties. The model also uses motor length E, which helps when planning cabinet depth, coupling clearance, and surrounding machine geometry.

For load holding, a standard spring-applied blocking brake is integrated to secure the axis when drive power is removed. Because the brake is spring applied, it is intended to hold the shaft at standstill rather than provide dynamic stopping during normal servo motion. The power lead exits through a connector on side A, which helps keep cable routing straightforward in compact assemblies. The unit is classified as a motor for analog drives, confirming compatibility with voltage- or current-controlled amplifiers that use ±10 V speed commands. This arrangement makes the motor suitable for continued use in legacy motion systems that still rely on analog control architecture.
