Product Description:

The QSK061C-0300-NN-S5-UG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the QSK Servo Motors series. Designed for closed-loop axis control in automated handling, packaging, and machining systems, the unit converts drive current into precise torque and speed that follow controller commands. By combining a compact stator with integrated feedback electronics, the motor delivers the position accuracy required for multi-axis gantries and pick-and-place robots in industrial automation lines.

Electrical and mechanical connections use a 240° rotatable plug. This angled connector lets cables be repositioned during installation to reduce bend stress inside cramped panels. Heat from the windings is removed by natural convection, so no fan or liquid circuit is needed, but clearance around the housing must be maintained. The motor is supplied without a holding brake, so external mechanical restraints must secure vertical axes. Rotor position is resolved by an optical encoder that outputs 128 counts per turn. Feedback travels over the Hiperface serial line, and the optical sensing principle helps keep signal noise low in electrically noisy environments.

The encoder performs a full-revolution measurement using a single-turn code disk, which is adequate when absolute positioning beyond one turn is tracked by the machine controller rather than the motor itself. The motor has a frame size of 061 with a frame length of C, giving a short stack that helps minimize inertia during rapid acceleration. Output torque is transmitted through a plain shaft with a shaft sealing ring, and the seal helps protect the front bearing from coolant spray common in machining centers. Winding code 0300 identifies the electrical characteristics matched to compatible drives that can supply the required current without excessive thermal rise.
