Product Description:

The QSK075D-0300-NN-M5-UG0-NNNN is a synchronous servo motor in the QSK Servo Motors series from Bosch Rexroth Indramat. Built for compact handling stations, packaging machinery, and electronic assembly cells, it supplies repeatable rotary motion that can be coordinated with multi-axis controllers. The motor includes internal feedback so the drive amplifier can issue velocity and position commands that maintain accuracy during rapid indexing cycles and continuous-duty operation in industrial automation lines.

The wiring exits through a rotatable 240° plug, so the cable bundle can be aligned with the cabinet wall and strain on the conductors can be reduced. Thermal energy is removed by natural convection, eliminating the need for fans or liquid loops and requiring only unobstructed airflow around the finned stator shell. Rotor position is captured by an encoder that provides 128 signal periods per revolution through the digital Hiperface protocol. Because the sensing element uses an optical scanning principle, signal jitter remains low and phase lag stays stable over temperature. Its multiturn absolute design stores shaft turns mechanically, allowing the system to power up with an exact angle reference and skip a homing routine on axes where end stops cannot be overtraveled.

The motor uses frame size 075 with frame length D, giving a slim stator stack that still houses winding code 0300 to match mid-current inverters. A plain shaft with a shaft sealing ring transfers torque into couplings while helping block lubricant from migrating toward the encoder chamber. The unit is supplied without a holding brake, so vertical or suspended loads must be secured by external means or maintained by continuous motor torque. Its synchronous magnetic construction preserves a fixed electrical angle between rotor and stator fields, providing constant torque density across the commanded speed range.
