Product Description:

The MAC093B-0-0S-3-C/110-B-2 is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Designed for closed-loop motion tasks, the unit transforms three-phase electrical supply into accurately regulated torque for packaging stations, gantry axes, and general assembly equipment. By delivering continuous rotation that is tightly synchronized with drive amplifiers, it forms a key actuator inside automation cells that demand repeatable positioning and smooth velocity transitions. Its operating profile is well suited to axes that require stable speed regulation during repeated starts, stops, and directional changes.

The motor’s holding mechanism supplies up to 14 Nm of braking torque, letting machinery remain fixed during shutdowns or safety interlocks. A centering pilot of 110 mm seats the flange concentrically to adjoining components so runout is minimized. Heat is dissipated through natural convection, eliminating auxiliary blowers and simplifying the surrounding layout. Position and speed signals are delivered through tacho feedback and a second shaft end. The auxiliary shaft accepts external sensors when higher resolution is needed. Incoming power is routed through a connector on side B, keeping high-voltage cables clear of the drive end. The frame designation 093 indicates the stator diameter used for this motor size and supports middle-range torque capability in conveyor or indexer duty.

The axial format identified by code B provides a moderate rotor length that balances inertia with acceleration response across typical duty cycles. Classified as a motor for analog drives, the MAC design interfaces directly with voltage-controlled amplifiers found in legacy installations while still supporting controlled motion. A heavy-duty blocking brake with spring-applied, electrically released operation secures loads on vertical or suspended axes. This arrangement allows the brake to engage when control power is removed and release during normal operation. Standard tacho quality keeps the velocity signal linear enough for most analog control bandwidths.
