Product Description:

The MAC093B-0-ES-4-C/110-B-2/WI634LX is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed as a motor for analog drives, it supplies precise rotary motion and position control to automated machinery used in packaging, printing, and material-handling cells. The model fits drive chains that rely on external analog amplifiers for current regulation, making it suitable for retrofit or legacy systems that accept voltage-controlled command interfaces. In these installations, the motor supports repeatable motion on feed rollers, transfer axes, and other mechanisms that depend on stable closed-loop response during changing load conditions.

Persistent torque retention is handled by a heavy-duty blocking brake that clamps the shaft when power is removed. Its holding capacity reaches 14 Nm, which helps prevent back-drive on vertical or high-inertia loads. Mechanical alignment to gearboxes or couplings is aided by a 110 mm centering diameter that keeps the housing concentric to mounting fixtures. Heat produced by copper losses is dissipated through natural convection, so no fan or external coolant is required. The rotor can reach a nominal speed of 6000 rpm, which supports high-speed indexing while keeping commutation frequencies within the limits of analog amplifier operation.

The wiring scheme uses a connector on side B layout, which routes power cables away from encoder leads to help reduce signal noise. The standard tachometer generates 1.5 V/1000 rpm, providing velocity data to the drive without additional scaling hardware. Position information comes from an incremental encoder with standard mounting, and the motor also accepts absolute encoder assemblies through the shared tachofeedback interface for applications that need multi-turn position memory. The internal copper uses winding code ES, which sets the electrical characteristics used with compatible MAC drive modules. The size 093 frame and length B housing create a compact unit that installs easily in space-restricted areas while still delivering sufficient torque for mid-range automation axes.
