Product Description:
Bosch Rexroth Indramat’s QSK061C-0300-NN-M5-UG0-NNNN belongs to the QSK Servo Motors series and is built as a synchronous servo motor for closed-loop industrial axes that need precise velocity and position control. The motor integrates with drive controllers across packaging, assembly, and semiconductor lines where compact dimensions and high-resolution feedback are required to coordinate multi-axis motion stages. Its synchronous design allows the connected drive to regulate torque accurately during indexing, short settling moves, and repeated start-stop cycles. This arrangement supports applications that rely on repeatable motion paths and stable feedback during continuous production. It is suited to servo systems where axis response must remain consistent under frequent speed changes.
Power and feedback conductors are routed through a 240° rotatable plug, letting the connector be turned to match cabinet or machine layouts. The motor uses frame size 061, so the mounting interface and stator diameter stay consistent with other motors in the series. Position data is exchanged over the Hiperface interface, a serial link that carries both commutation and absolute position information and reduces wiring to a single hybrid cable. The optical encoder resolves one revolution into 128 increments, which supports fine interpolation by the drive for smooth low-speed motion. Torque is transferred by a plain shaft with a shaft sealing ring, which helps keep lubricant away from the encoder cavity while allowing direct coupling to belt pulleys or clamp hubs.
Heat is removed solely by natural convection cooling, so airflow around the housing must remain unobstructed when the motor is installed inside enclosures. The feedback device provides multi-turn absolute feedback, while the motor is supplied without a holding brake. The absence of a brake means holding force at standstill must come from the drive or from external mechanics. The motor uses winding 0300, which sets the electrical characteristics expected by the servo drive for current limits, inertia matching, and field-oriented control gains. Because cooling is passive, the housing can be installed in compact areas as long as surrounding air can circulate freely.
