Product Description:
The QSK061C-0300-NN-S5-UG1-NNNN synchronous servo motor is built by Bosch Rexroth Indramat within the QSK Servo Motors series. Designed for closed-loop automation, it converts drive current into accurately controlled mechanical rotation so that gantry axes, feeders, and tool changers reach commanded positions with minimal following error. Its electromechanical design supports integration with IndraDrive servo amplifiers and other digital drives used in packaging, assembly, and material-handling equipment. This operating role makes the motor suitable for applications that require repeatable motion, stable speed control, and dependable positioning during frequent start-and-stop cycles.
The motor uses a frame size 061 housing and an extended frame length C, which provide a larger lamination stack while keeping the outer cross section compact. The stator uses winding 0300, matching drive outputs that supply the appropriate voltage constant and phase current for this motor configuration. Power, feedback, and brake conductors terminate on a 240° rotatable plug, allowing the connection point to be turned for easier cable routing in confined machine spaces. Heat from the windings is removed by natural convection, so the motor does not require a separate blower or liquid cooling circuit. This layout supports clean installation where surrounding space is limited and uncomplicated thermal management is preferred.
Position feedback is supplied by an optical encoder with 128 encoder increments per revolution and Hiperface communication, allowing the drive to receive single-turn absolute position data and identify motor data automatically. An electrically released brake provides 10 Nm of static holding torque, and spring force clamps the rotor when supply voltage is removed to help prevent axis drift at standstill. Torque is delivered through a plain shaft with a shaft sealing ring, which helps protect the bearing area from contaminants while supporting direct coupling to pulleys or gearheads. This combination of feedback, holding capability, and shaft sealing suits axes that must hold position securely and return to controlled motion with consistent response.
