Product Description:
The QSK100B-0200-NN-M5-BG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the QSK Servo Motors series. As a closed-loop drive element, it converts commanded current from a servo amplifier into precise angular motion for positioning or speed-regulated industrial axes such as pick-and-place arms, linear actuators, and conveyor drives. Its electromagnetic design delivers repeatable torque, while the integrated feedback device supplies real-time shaft data to the motion controller for stable multi-axis coordination. This makes the motor suitable for automated equipment that requires accurate motion and consistent response under changing load conditions. The feedback path allows the controller to correct position and speed continuously during acceleration, indexing, and dwell periods.
Electrical integration is simplified because the power and feedback leads exit on the B-side, and a single industrial connector mates with standard cable sets. This arrangement keeps external wiring compact, supports orderly routing in confined machine spaces, and reduces the number of separate cable interfaces at the motor. Heat generated in the stator is removed by natural convection, so no fan or liquid circuit is required. The stator winding code 0200 corresponds to the motor's electrical characteristics, and the motor has frame size 100 with frame length B plus a plain shaft with a sealing ring for use in compact machine frames.
Position feedback relies on an incremental base resolution of 128 steps per mechanical turn, extended by magnetic counting across multiple turns. Data is transmitted through the bidirectional Hiperface interface, and the sensing element uses an optical grating to minimize hysteresis during position detection. Because the encoder is multi-turn absolute, it preserves shaft position through power interruptions and removes the need for a homing routine at startup. The sensing system supports stable feedback across changing speeds and repeated positioning cycles. During standby, the brake provides 32 Nm of static torque to hold the rotor in place on vertical or inertia-loaded axes.
