QSK075E-0300-NN-M5-UG1-NNNN

The QSK075E-0300-NN-M5-UG1-NNNN from Bosch Rexroth Indramat belongs to the renowned QSK Servo Motors series, offering a robust synchronous servo motor design with B5 flange mounting style and a Frame Size of 075 for versatile integration. This model operates at an Operating Voltage of 320 V and delivers a peak Torque of 3 Nm while achieving an operating speed of 3000 RPM, ensuring precise motion control. Encased in an IP65 rated enclosure, the motor is protected against dust and water ingress, making it suitable for harsh industrial environments. With a compact Frame Length E configuration and a lightweight build of just 5.5 kg, this servo motor balances power density with ease of installation.

The technical capabilities of the QSK075E series are highlighted by its high-resolution Hiperface encoder interface paired with a multiturn-absolute encoder turn type, delivering accurate position feedback and rapid response times. Its plain shaft with shaft sealing ring ensures reliable torque transmission and prevents contamination ingress along the axle. The integrated Holding Brake Torque of 23 Nm secures loads in hold positions without power, while the Winding designation 0300 provides consistent performance under varying loads. Power management is optimized through a rotatable 240° plug connection type, simplifying cabling in confined spaces and facilitating maintenance.

Operational efficiency is enhanced by the motor’s natural convection cooling method, which dissipates heat without the need for auxiliary fans or liquid cooling systems. This passive cooling strategy reduces maintenance requirements and improves overall system uptime. A low Power Consumption of 20 W during standby and minimal thermal stress contribute to energy savings, while the motor’s robust Protection IP65 rating ensures uninterrupted operation in dusty or wet conditions. Backed by a One-year warranty, the QSK075E-0300-NN-M5-UG1-NNNN offers reliability and long-term performance in demanding industrial settings.

Designed for seamless integration, this servo motor’s B5 flange mounting and standardized dimensions support direct replacement in existing machine frames and quick adaptation in new designs. Its advanced encoder interface and communication flexibility make it ideal for CNC machinery, robotics, packaging systems, and automated assembly lines. Engineers can leverage its precise control and high dynamic response to optimize manufacturing throughput and quality. The QSK075E series exemplifies Bosch Rexroth Indramat’s commitment to delivering reliable, high-performance motion control solutions for today’s industrial automation challenges.
