Product Description:

The QSK075D-0300-NN-M5-UG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the QSK Servo Motors series. In automated handling stations and indexing tables, this motor supplies closed-loop torque and position control to rotary axes that require fast settling and repeatability. Its construction follows the modular QSK platform, letting machine builders match winding, encoder, and mechanical options to duty-cycle needs while maintaining a compact envelope for cabinet or gantry mounting. The design is well suited to rotary axes that cycle frequently and must return to commanded positions without wide settling variation.

The connector can be rotated through 240°, allowing the cable exit to align with panel layout. Heat generated in the stator is removed by natural convection, so an external blower is unnecessary under the rated load curve. An integrated feedback unit delivers 128 increments per revolution to the drive via the Hiperface protocol, and its optical scanning method maintains resolution without magnetic drift. The encoder stores multi-turn data mechanically, allowing absolute position recovery after power-off and supporting controlled restarts after planned stops. Frame length D balances torque capacity with limited depth for packaging and assembly equipment.

The feedback system has multi-turn absolute capability, so position data over several shaft revolutions is retained without battery support. For load holding, an electrically released brake supplies 23 Nm of static torque and engages automatically when power is removed. Mechanical sizing follows frame size 075, and winding code 0300 indicates the copper fill and resistance used with medium-voltage inverters. The motor uses a plain shaft with a sealing ring, which helps limit contaminant entry at the output journal and supports direct coupling to connected machine elements.
