Product Description:

The MAC041B-0-BS-2-E/050-A-1/S001 is an AC servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed to pair with analog drive amplifiers, the unit converts command voltages into precise shaft motion for positioning, speed regulation, and coordinated movement in automated machinery such as pick-and-place gantries or small transfer stations. Integrated feedback allows the external amplifier to monitor motor response during closed-loop operation. This arrangement supports small axes that need repeatable starts, stops, and stable low-speed control.

Its frame uses motor size code 041 and length code B, indicating a compact build that reduces inertia while preserving torque density. The compact frame helps keep moving mass low, which supports responsive acceleration on light-duty axes. Thermal management is handled through natural convection, so heat dissipates across the housing surface without external fans or liquid circuits. Position and velocity data are returned to the drive through integrated tacho feedback, enabling continuous analog speed loops with minimal phase lag. Electrical power is routed through a connector on side A, allowing the cable to exit toward the drive cabinet and maintain consistent bend radii inside tight enclosures.

For holding functions during shutdown, a standard blocking brake is supplied; it clamps the rotor automatically when the drive disables torque so vertical or indexing axes remain stationary. The brake also helps keep the axis in place during pauses when drive torque is removed. The unit is classified as a motor for analog drives, so its back-EMF constant and tachogenerator scaling are matched to voltage command stages rather than digital field-oriented controllers. This feedback arrangement suits control loops that rely on stable speed-proportional signals from the motor.
