Product Description:

The MAC041B-0-BS-3-E/050-B-0/S006 is an AC servo motor supplied by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for position and velocity control in analog drive systems, it translates command voltages from legacy motion controllers into precise rotary movement for assembly stations, pick-and-place heads, compact gantry axes, and similar automated equipment. Its mechanical envelope and electrical interface are arranged for direct replacement in applications where existing analog hardware must remain in service and changes to surrounding machine components need to be kept minimal.

The motor size is 041, giving it a narrow cross-section that fits 58 mm mounting flanges while maintaining the torque margin needed for light automation tasks. The housing uses length code B, which keeps the overall motor length short enough for restricted Z-axis installations and other compact machine spaces. Mains power enters through a connector on side B, which routes cabling away from the driven load and helps keep the connection path clear. Heat is removed entirely by natural convection, so no external blower is required for normal cooling. Shaft speed is monitored with integrated tacho feedback, which delivers an analog voltage proportional to rpm so legacy controllers can close the velocity loop without digital scaling.

A second shaft end is provided for users who need to attach an auxiliary encoder, handwheel, or belt pulley without altering the primary coupling. Because there is no blocking brake, vertical or inclined axes must rely on external clamps or continuous drive torque to hold position when power is removed. The winding constants and tachometer scaling align with reference tables used in analog drives, which supports retrofit work on older machine platforms where the original command structure and feedback scaling must be preserved.
