SR-A3.0042.030-00.000

The Bosch Rexroth Indramat SR-A3.0042.030-00.000 servo motor from the SR Synchronous Servo Motors series offers a compact yet powerful solution optimized for industrial automation tasks. It delivers high torque density through its robust 3-phase design and integrates a permanent magnet holding brake for secure stops and drift-free positioning. With built-in IP67 protection, this model operates reliably in dusty or wet environments without additional enclosures. The integrated resolver encoder provides precise position feedback, ensuring tight motion control and smooth acceleration across varying load conditions. Engineered for applications demanding repeatable accuracy, the motor weighs only 7 kg and supports a rated load of 2 HP.

The technical specification profile highlights the motor’s operational envelope and key parameters. It runs on 230 V input voltage in a 3-Phase configuration with frequency inverter drive compatibility. Cooling is achieved by radiation and natural convection, enabling maintenance-free heat dissipation within an ambient temperature range of 0…40 °C. The mounting flange conforms to IEC 72-2 / DIN 42 948 standards for straightforward mechanical integration. The built-in resolver encoder ensures accurate feedback, while the moment of inertia of 7×10^-4 kg·m² supports rapid dynamic response. Noise emissions are limited to max. 58 dB(A) at 1.0 m, minimizing acoustic impact. The IP67 protection type shields the internal components from moisture and particulates.

Operational features of the SR-A3.0042.030-00.000 emphasize continuous, reliable performance under industrial conditions. The natural convection cooling scheme eliminates the need for auxiliary fans or liquid cooling circuits, reducing system complexity. The permanent magnet brake provides zero-backlash holding torque when power is removed, enhancing safety during maintenance or emergency stops. The resolver encoder offers high resolution feedback without battery backup, enabling immediate position recall after power cycles. The motor’s compact form factor and low mass facilitate agile installation in robotics, gantry axes, or conveyor systems where inertia and footprint must be minimized.

System integration is seamless when paired with standard frequency inverter drives, supporting advanced control algorithms and auto-tuning routines. The SR-A3.0042.030-00.000 is well suited for applications in packaging machines, printing equipment, CNC tools, and material handling systems where precise, smooth motion is critical. Its compliance with common flange and electrical standards accelerates project timelines and simplifies spare-parts management. Designed by Bosch Rexroth Indramat for durability and scalability, this servo motor meets the stringent demands of modern industrial automation networks.
