Product Description:

The MSK071C-0300-FN-M1-UG2-NNNN is a servo motor engineered by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts electrical power from a drive controller into tightly regulated rotary motion, making it suitable for coordinated axes in machine tools, pick-and-place modules, and other automated stations. By pairing a compact electromagnetic design with integrated encoder feedback, the motor supports accurate speed control and position holding that are essential for repeatable production cycles. The motor is well suited for servo applications that require responsive motion during indexing, contouring, and other repetitive machine movements.

Thermal management for this model relies on liquid cooling, so an external coolant circuit must be connected before operation. Removing heat through the housing allows the 71 mm frame, identified as size 071, to maintain continuous torque capability even though the body length is given as code C. An electrically released holding brake rated for 30 Nm keeps the shaft locked during power-off conditions, which is useful on vertical axes. Mechanical integration is supported by a plain shaft and by a rotatable feedback connector that can swing through 240°, giving more flexibility for cable routing in tight machine spaces.

Position feedback is supplied by an integrated encoder that communicates over Hiperface. The scanning head uses an optical principle to detect 128 signal periods around the code disk, producing fine incremental data for phase alignment. Multi-turn absolute capability lets the motor report its mechanical revolution count after a power loss, so the controller can resume motion without a reference move. Electromagnetic behavior is linked to winding set 0300, whose resistance and inductance match IndraDrive current regulators for smooth torque across the speed range without excessive heating.
