Product Description:

The MAC041C-0-TS-4-E/050-B-1/WI671LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. This motor functions as a torque and position actuator in analog drive systems for automated machinery where precise speed regulation and closed-loop positioning are required. Its electromechanical design integrates the stator, rotor, and feedback devices into a compact housing suited for machine-mounted drive axes. The integrated feedback system allows a compatible amplifier to monitor shaft motion and correct deviations caused by changing loads during operation.

The motor has a frame size of 041, which establishes the flange pattern and shaft height, while its C length provides the active stack depth associated with its continuous torque capability. Copper utilization and thermal behavior are matched to analog amplifiers through the TS winding, which has the appropriate resistance and inductance values for this motor configuration. Heat is removed solely by natural convection, eliminating the need for an external blower or liquid-cooling circuit. Power conductors enter through a connector on side B, directing the cable run away from gearboxes or adjacent axes and simplifying routing within the machine. The compact housing and passive cooling arrangement also reduce the number of auxiliary components required around the installation.

A standard blocking brake is integrated to hold the shaft when control power is removed, helping prevent load drift on vertical or high-inertia axes. Velocity information is delivered through tachofeedback with an incremental or absolute encoder, supporting speed regulation and accurate positioning through a compatible controller. Position reporting is provided by an incremental encoder with standard mounting, ensuring compatibility with legacy analog controllers that use referenced zero markers. The unit is a motor for analog drives and supports installations that rely on ±10 V command signals and traditional current-loop amplifiers. Its feedback arrangement supplies the motion data needed by the external drive to regulate velocity and position without placing the control electronics inside the motor housing.
