MAC090A-0-RD-1-B/110-A-0/-I00625/S001

The MAC090A-0-RD-1-B/110-A-0/-I00625/S001 is a high-performance member of the MAC AC Servo Motors series by Bosch Rexroth Indramat designed for demanding industrial automation applications. This model features a robust protection category IP65 for full dust ingress protection and resistance to water jets, ensuring uninterrupted operation in harsh environments. The motor delivers a nominal motor speed of 3000 min⁻¹ for high-cycle throughput and precise motion control. A substantial centering diameter of 110 mm provides reliable mechanical integration, while the torque constant at 20°C of 0.34 Nm/A guarantees consistent torque delivery. With a compact motor length A and a motor size of 90, it integrates seamlessly into space-constrained assemblies. Its continuous current at standstill of 11.4 A supports steady torque at zero speed, making it ideal for holding-driven applications.

Performance characteristics of the MAC090A-0-RD-1-B/110-A-0/-I00625/S001 highlight its ability to withstand dynamic loads and thermal stress. The windings inductance of 3.2 mH and a windings resistance at 20°C of 0.56 Ω are optimized to minimize electrical losses and enhance current responsiveness. Peak demands are met by a maximum peak pulse current of 76 A, enabling brief overload handling without compromising stability. The motor’s thermal time constant of 45 min allows for extended duty cycles before requiring cooldown, while the rotor moment of inertia of 20 × 10⁻⁴ kg·m² supports smooth acceleration and deceleration profiles. For precise speed feedback, the motor incorporates a tachogenerator voltage constant of 6 V/1000 min⁻¹. Cooling is managed through natural convection or surface cooling, which simplifies installation in closed or ventilated enclosures.

Engineered for reliability and easy integration, the MAC090A-0-RD-1-B/110-A-0/-I00625/S001 excels in a variety of industrial sectors. The incremental encoder with standard mounting ensures accurate position feedback and straightforward retrofit into existing control systems. Operating in a permissible ambient temperature range of 0°C to +45°C, it maintains performance across typical factory environments. Weighing 12.5 kg, the servo motor balances robustness with manageable mass for equipment designers. Its rugged IP65 housing and proven Bosch Rexroth Indramat quality support long service life in applications such as assembly machines, packaging systems, and CNC automation platforms where consistent precision and uptime are critical.
