MAC093B-0-JS-4-C/130-B-0/WA612XX
The Bosch Rexroth Indramat MAC093B-0-JS-4-C/130-B-0/WA612XX is a high-performance AC servo motor from the renowned MAC AC Servo Motors series, designed to meet the rigorous demands of modern industrial automation. This MAC Permanent Magnet Motor integrates advanced electronic commutation with a permanent-magnet rotor and precision stator windings to deliver smooth, responsive motion control. It features a size 093 housing with convection cooling and a B-length frame configuration, ensuring compatibility with a wide range of drive systems. The motor’s integrated feedback system includes a B encoder and optional blocking brake, enhancing closed-loop stability and positional accuracy. With an overall mass of 16.5 kg, this unit balances robustness with manageable weight for streamlined machine integration.
Performance is characterized by a continuous current at standstill of 27 A (34 A peak)(27 (34)^5)), yielding a continuous torque at standstill of 14.5 Nm (18.3 Nm peak) and a maximum peak of pulse current of 134 A for dynamic load responses. The motor delivers a nominal speed of 3000 min^-1 and a torque constant of 0.554 Nm/A at 20°C, ensuring precise speed–torque correlation across the operating range. Electrical parameters include windings inductance of 4.0 mH and windings resistance of 0.227 Ω at 20°C, which combine to define the motor’s electrical time constant for rapid current regulation. The rotor’s inertia of 29 x 10^-4 kg·m² provides optimized acceleration characteristics, while a thermal time constant of 50 min (45 min)^5 affords predictable thermal behavior under continuous operation. These features work in concert to minimize torque ripple and maximize dynamic response.
Constructed for reliability in harsh environments, the MAC093B motor boasts an IP65 protection rating that shields internal components from dust and water ingress, minimizing unplanned downtime. Integrated thermoswitches monitor winding temperatures in real time, enabling safe operation at elevated loads and ambient temperatures. Its modular power connector on side B allows straightforward cabling and maintenance without dismantling the entire assembly. Compatible with a broad portfolio of Bosch Rexroth drives and controllers, this servo motor delivers seamless integration into existing automation architectures. Ideal for robotics, printing machinery, handling systems, and transfer lines, the MAC093B-0-JS-4-C/130-B-0/WA612XX ensures exceptional repeatability, long-term durability, and optimal throughput in demanding industrial applications.
