The MAC115B-1-ES-4-C/130-A-1/WI524LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and placed within the MAC AC Servo Motors series. Intended for analogue drive systems, it transforms electrical input into controlled rotary motion for presses, packaging lines, and material-handling axes. By combining permanent-magnet excitation with integrated position feedback, the unit delivers repeatable torque and speed that sustain closed-loop automation. Its mechanical configuration also meets mid-frame machine layouts where limited depth and high continuous torque are required.
Its built-in blocking brake supplies 45 Nm of static holding torque, keeping vertical or load-bearing shafts secure during power loss or tool changes. Thermal stability is maintained by an auxiliary blower rated at AC 230 V; together with Axial Surface Cooling this prevents derating during high-duty cycles. A centering pilot of 130 mm aligns the flange precisely with gearboxes or mounting plates. Motion feedback is generated by an Incremental encoder with standard mounting, and a tacho coil can be added when finer speed linearity is required. The ground steel shaft features a DIN 6885 keyway, enabling direct coupling to pulleys or gears without additional machining.
The frame corresponds to motor size 115, while the depth is identified by length code B, giving a favorable power-to-length ratio for retrofits inside shallow cabinets. Electrical behavior is defined by the ES winding code, allowing analogue amplifiers to predict phase current and back-EMF values without recalibration. Three-phase power leads connect through a connector to side A, keeping high-voltage wiring separate from encoder lines on the opposite face. Standard tacho quality and an optional absolute encoder variant expand compatibility with analogue or hybrid control loops.
