Product Description:

The MAC093B-0-GS-4 C/110-B-0/WI522LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it delivers position and velocity control to automation axes that rely on current-mode amplifiers rather than fully digital interfaces. Its mechanical outline follows the MAC family format, allowing it to fit machine tools, handling modules, and packaging equipment that use this motor series for closed-loop axis motion.

The motor’s centering pilot follows a diameter of 110 mm, giving a fixed reference surface for concentric mounting to gearboxes or rigid machine frames. Heat dissipation is handled only through natural convection; no fan or liquid circuit is required, so enclosure layouts stay simple. A rated speed of 4000 rpm supports rapid traverse moves while still permitting precise low-speed control during machining or dosing tasks. This speed range is useful on axes that alternate between quick positioning and controlled process movement. The stator uses a GS winding, which indicates the electrical resistance and inductance values expected by the analog drive. Physical sizing follows the MAC B length on a size 093 frame, a balance that yields moderate continuous torque without excessive mass.

Torque and speed feedback are routed through a connector on side B, which keeps power and signal cables clear of the driven shaft area. Inside the housing, an incremental encoder delivers position data while an integral tacho generator supplies velocity feedback, both built to standard tacho quality for consistent loop tuning across multiple axes. The unit is supplied with no blocking brake, so external clamping or drive torque must secure the load when power is removed. This arrangement suits systems that use separate feedback channels for stable response at both low and operating speeds. The encoder, tacho, and winding identifiers support compatibility with analog velocity and position regulators that use the MAC coding system.
