Product Description:
The QSK075C-0300-NN-S5-UG1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the QSK Servo Motors series. It connects to a drive controller to generate precise rotary motion in automated pick-and-place axes, packaging stations, and light machining centers where repeatable positioning is critical. By combining torque production, feedback, and an internal brake in one housing, the motor serves as a compact actuator for tightly coordinated multi-axis systems. This arrangement supports accurate start-stop motion and steady position control in machines that must repeat short cycles throughout normal operation.
Thermal management relies on natural convection, so the unit operates without external fans and can be installed where simple cooling is preferred. The frame uses size 075 with length code C, providing the iron volume needed for winding code 0300 and supporting stable operation during repeated motion cycles. A holding brake rated at 23 Nm uses an electrically released mechanism, so it clamps the shaft whenever control power is removed. Rotor position is detected by an encoder that provides 128 increments per revolution through the Hiperface interface, supplying incremental and absolute data for drive regulation. That signal structure helps the controller maintain coordinated motion, correct position error, and respond smoothly to changing load conditions.
The feedback system uses an optical scanning technique in a single-turn configuration, so the controller receives an absolute angular value within one mechanical revolution. Additional revolutions are tracked by the control system during operation, which suits axes that return to known reference positions as part of normal machine sequences. Power and signal conductors terminate in a 240° rotatable plug, which helps route cables around nearby guards, tooling, or structural members without forcing a fixed exit direction. Output torque is transmitted through a plain shaft fitted with a shaft sealing ring that helps retain lubricant and reduce the entry of dust or fine debris. This shaft arrangement is suitable for direct coupling to external drive elements while keeping the motor end compact and easy to integrate.
