Product Description:

The QSK075E-0300-NN-M5-UG1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the QSK Servo Motors series. It serves as a drive element that converts electrical input into regulated rotary motion for automated pick-and-place units, indexing tables, and packaging machinery. Its synchronous design supports accurate speed and position control when paired with a compatible servo drive. This model uses frame size 075 combined with frame length E and winding code 0300, a configuration chosen to balance continuous torque capability with moderate current draw.

Heat dissipation relies on natural convection, so no external blower or liquid circuit is needed and enclosure design stays simple. Power and feedback leads terminate in a 240° rotatable plug, allowing cabling to be directed toward the cabinet roof, floor, or side wall without exceeding bend-radius limits. An optical feedback disk provides 128 incremental counts per revolution, giving fine speed resolution at low frequencies and supporting smooth motion at reduced speed. Position data travels through the Hiperface interface, while an optical scanning method helps keep signal quality consistent during vibration and temperature changes.

Absolute position over multiple turns is retained by a multi-turn absolute encoder that continues counting even when external power is removed. For safety on vertical axes, an electrically released brake delivers 23 Nm of static torque and engages automatically on power loss. The compact 075 frame mates directly with gearheads or couplings through a plain shaft with a shaft sealing ring, which helps block lubricant ingress and keeps internal motor components protected. This arrangement suits enclosed machine sections where stable feedback, secure holding, and clean power transmission are required during repeated motion cycles.
