Product Description:

The MAC041B-0-BS-4-E/050-A-0/WI671LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for tightly regulated motion axes in light-duty automation, the motor transforms analog velocity or torque commands from a drive amplifier into controlled mechanical rotation. By linking the electromagnetic field of its stator with permanent magnets on the rotor, it provides smooth continuous torque for pick-and-place devices, indexing tables, and compact machining equipment. This operating principle allows the motor to respond quickly to changing commands while maintaining stable motion on short-cycle positioning tasks.

Thermal management uses natural convection, so the exterior fins release heat directly to ambient air without forced ventilation. Power is delivered through a keyed plug with a connector on side A, which keeps power and ground conductors on the same mounting face and simplifies cable routing. Dimensional codes indicate a frame size of 041 and a frame length of B, and position feedback is supplied by an incremental encoder with standard mounting for real-time commutation and velocity control. The encoder pulses give the controller the timing information needed to correct speed deviations and maintain accurate shaft motion during repetitive indexing.

The motor also uses tacho feedback to provide a speed-related signal for the drive amplifier during closed-loop operation. Because no blocking brake is installed, the axis must rely on drive torque or an external clamp to hold the load when power is removed. Classified as a motor for analog drives, the unit matches legacy amplifier signal levels and cable pinouts, allowing it to be used in existing machinery without changing cabinet hardware. This layout supports continued use with installed analog control hardware where stable speed feedback and direct compatibility are more important than adding newer digital interfaces.
