The QSK100B-0200-NN-M5-AG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the QSK Servo Motors series. In automated machinery the unit converts commanded electrical power into tightly regulated rotary motion, supplying precise torque and position control for axes that handle indexing, material transfer, or light machining tasks.
Power and feedback cabling is routed on the A-side, and all terminations are made through a single Connector housing that simplifies cabinet wiring. Heat produced by copper losses is released to ambient air through Natural convection; no fan or liquid circuit is required, so maintenance points are reduced. Position feedback is generated by an integrated optical encoder that resolves shaft rotation into 128 increments per mechanical revolution, providing adequate granularity for coarse-to-medium accuracy loops. The design omits a holding brake, so static load retention must be achieved with drive torque or external clamps. A plain shaft with a shaft sealing ring prevents lubricant egress and blocks particle ingress at the output end, supporting operation in general-purpose enclosures.
The mechanical envelope follows a frame size of 100 mm and a frame length code of B, giving designers a predictable mounting footprint across the series. Digital feedback is transferred through the bidirectional Hiperface protocol, which overlays absolute data on the incremental tracks read by the Optical sensing elements. Multiturn counting is inherent because the encoder is of the Multiturn-absolute type, so the controller receives valid position information immediately after power up without homing. Stator characteristics are defined by winding code 0200, which fixes voltage constant and thermal limits for drive pairing. All rotational energy is delivered through the plain shaft, while the absence of a holding brake lowers rotor inertia for faster dynamic response.
