Product Description:

The MAC041C-0-LS-2-E/050-A-1 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is intended for closed-loop rotary axes on analog drive amplifiers, where accurate torque delivery and speed regulation are needed in assembly stations, transfer lines, and light-duty packaging equipment. The unit converts electrical setpoints from the controller into proportional mechanical rotation, allowing downstream motion elements to execute precise cycles in automated processes. Its compact format suits axes that need repeatable motion without the size of a larger motor frame.

On the thermal side, the motor relies on natural convection; heat leaves the aluminum housing without fans, so airflow paths must remain open. Rotor velocity feedback is generated by integrated tacho feedback, providing the drive with a voltage directly proportional to revolutions per minute for stable velocity loops. Dimensional identifiers include the frame length code 041 and the frame size designation C, a combination that fixes the active stack height and flange geometry for pairing with gearboxes or mounting plates. Power is supplied through a connector on side A, which helps route cables cleanly when the drive cabinet is positioned on that side of the motor.

For load-holding situations, a standard blocking brake is integrated; it locks the shaft whenever the amplifier is disabled to prevent drift on vertical or indexing axes. The winding code LS indicates the electrical characteristics expected by the matching drive, including the voltage and current relationship used for stable operation. Because it is a motor for analog drives, command inputs are handled as voltage or current references rather than digital fieldbus words. This arrangement supports legacy motion systems that require servo response with familiar analog control architecture.
