The Bosch Rexroth Indramat MAC093B-1-JS-4-C/110-B-1/WI520LV/S005 is a high-performance unit in the MAC AC Servo Motors series, engineered for precision motion control in industrial automation. This part, identified by part_number MAC093B-1-JS-4-C/110-B-1/WI520LV/S005, combines a 093 Motor Size with a B Motor Length within a robust cast-iron frame. The stator is constructed from thin, high-permeability steel laminations to minimize eddy losses and support uniform magnetic flux distribution. On Side B, a sealed power connector ensures reliable electrical interfacing, while an integrated standard blocking brake provides immediate holding torque without external devices. Encased in an aerodynamic axial fan housing, the unit benefits from Surface Cooled operation that enhances thermal dissipation and maintains compact dimensions (Mass 16.5 kg).
Performance characteristics focus on dynamic response, torque density, and thermal resilience. At standstill, the motor can handle a Continuous Current at Standstill 27 A (peak 34 A), generating a Continuous Torque at Standstill 14.5 Nm (peak 18.3 Nm). Short-duration peak pulse currents up to Maximum Peak of Pulse Current 134 A enable rapid acceleration for high-inertia loads. The MAC093B maintains a Nominal Motor Speed 3000 min^-1 with smooth operation supported by a rotor inertia of 29 x 10^-4 kg·m², optimizing control loop tuning. Electrical parameters include a Torque Constant 0.554 Nm/A at 20 °C, Windings Inductance 4 mH, and Windings Resistance at 20 °C 0.227 Ω, yielding a balance of torque production and bandwidth. A Thermal Time Constant 50 min allows sustained operation under continuous load before temperature limits are reached.
Reliability and system integration are guaranteed through precise mechanical design and modular interfaces. The laminated stator assembly in a sturdy frame delivers mechanical integrity and vibration resistance, while the keyway shaft coupling ensures positive torque transmission. The standard Incremental Encoder provides incremental position feedback, resetting to zero at power-up for consistent indexing. The built-in blocking brake secures the axis in case of power loss or emergency stops, minimizing downtime. Suited for applications in robotics, CNC machining, packaging, and material handling, this servo motor offers a plug-and-play solution when paired with compatible Bosch Rexroth drives and controls.
