QSY071B-030-HG1-UN
QSY Synchronous Servo Motors
The Bosch Rexroth Indramat QSY071B-030-HG1-UN from the QSY Synchronous Servo Motors series is a Frequency Inverter Drive tailored for precision-driven industrial automation. It operates on an Input Voltage of 230 V across a 3-Phase system and delivers a Maximum Torque of 5.5 Nm with a Rated Speed of 4500 rpm. The motor’s Rotor Inertia of 1.8 kgcm² ensures precise dynamic response and minimal settling times in demanding motion-control applications. Built with M6 mounting screws and a compact footprint, it integrates seamlessly into high-density machine architectures.
The 3-Phase (Phases: 3) drive sustains a Rated Voltage of 310 V / 308 V and draws a Rated Current of 1.1 A / 1.0 A under nominal load, supporting a Rated Load of 2 HP in continuous service. In heavy-duty cycles, it can handle a Maximum Current of 6.3 A while preserving torque linearity across the speed range. In fault or hold conditions, the Stall Torque of 1.5 Nm is curtailed by the Stall Current of 1.5 A to mitigate thermal stress. With a total Mass of 3.6 kg, the motor balances compactness with mechanical stability.
The motor’s Type: Frequency Inverter Drive architecture and advanced control capability deliver smooth torque transitions and precise acceleration profiles throughout the 0–4500 rpm range. Compliance with industry-standard interfaces enables seamless synchronization with modern PLCs and CNC controllers, while its robust construction supports regenerative energy recapture. This high-performance solution elevates productivity and reliability in advanced industrial automation environments.
