Product Description:

The MAC041B-0-BS-3-E/050-B-1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It serves as the rotary actuator in analog motion loops, translating current setpoints into mechanical torque for industrial positioning and speed control across automated equipment. Typical deployment includes assembly cells, pick-and-place gantries, and light machining axes where compact dimensions and repeatable response are required. Its integrated design allows the motor to work with compatible external amplifiers for closed-loop motion tasks in compact machine layouts.

Inside the motor housing, a blocking brake is fitted. It mechanically locks the shaft to help prevent drift on vertical or indexing loads. The brake uses the standard configuration, so its holding torque and release voltage match the default values used by MAC servo amplifiers. Heat generated by the windings is removed through natural convection, eliminating the need for fans or liquid jackets. Rotor velocity feedback is provided by tacho feedback, which supplies an analog voltage proportional to speed for continuous-loop regulation. The electromagnetic stack corresponds to frame size 041, giving the motor a compact profile with balanced torque output for light to medium-duty axis movement.

The motor has a B frame length, which sets the housing depth within the 041 frame platform. A second shaft end is available on the non-drive side, allowing attachment of auxiliary devices without changing the main output connection. Power is routed through a connector on side B, so cable routing can be directed toward that face of the machine enclosure. The unit is a motor for analog drives, meaning its winding constants, feedback scaling, and brake voltage are intended for Indramat analog amplifier cards rather than later digital controllers. This arrangement supports applications that rely on stable speed feedback and direct integration with established analog drive systems.
