Product Description:

The MAC041B-0-BS-4-E/050-B-1/WI673LV/S001 is an AC servo motor in the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is intended for analog drive systems in which legacy proportional controllers provide precise velocity and torque regulation rather than relying on fully digital interfaces. This design allows the unit to provide closed-loop motion for pick-and-place gantries, small transfer stations, and compact tooling axes that use analog command voltages. Its compact form also makes it suitable for machinery where the available installation space is limited.

The motor uses natural convection, so heat dissipates through the frame surface without auxiliary fans or liquid cooling circuits. A standard blocking brake holds the shaft when power is removed, helping prevent drift on vertical or loaded axes. The motor has a frame size of 041 and a B length, resulting in a short housing that fits within tight machine compartments. Mains and feedback conductors exit through a single connector on side B, simplifying cable routing along the rear of the axis. This arrangement keeps the front face unobstructed for the coupling hardware and connected mechanical components.

The motor uses insulation and bearing classes suited to continuous start-stop cycles in automated machinery. Its internal resolver and tacho circuit provide velocity feedback compatible with conventional analog control loops. For higher-resolution positioning tasks, the integrated sensor assembly includes an incremental encoder with standard mounting that sends quadrature signals to external counters or high-speed PLC inputs. The incremental channels allow connected control equipment to track changes in shaft position and direction during indexed movement. These feedback devices support speed-regulated conveyor operation and position-indexed assembly processes without requiring an additional external feedback assembly.
