Product Description:

The MSK071C-0300-FN-S1-UG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, this motor converts controlled electrical power into precise rotary motion that can be coordinated through a drive controller. Its construction supports closed-loop positioning tasks where high torque density, compact dimensions, and stable thermal behavior are required on conveyor axes, packaging stations, and handling modules.

This model removes stator heat through liquid cooling, so full torque can be maintained even in tightly sealed cabinets. The electromagnetic circuit is identified by winding code 0300, which pairs the motor with drives that supply the matching voltage and current profile. Mechanical dimensions follow the MSK frame system: the frame is size 071 and the active stack is the medium C length, giving an inertia that balances dynamic acceleration with load stability. Output torque is transmitted through a plain shaft that simplifies coupling to gearboxes or timing pulleys without keyways and reduces shaft-end stress concentrations.

Feedback takes place over the Hiperface digital interface, allowing simultaneous power and data routing through a rotatable 240° connector for flexible cable egress. Position accuracy is supported by an encoder resolution of 128 signal periods, produced by an optical scanning system that limits interpolation error. Because the encoder is single-turn, one electrical revolution yields absolute position information while multi-turn data must be derived in the drive. There is no holding brake installed, so static load retention relies on the drive’s torque control or an external mechanical lock. The standard design housing accepts liquid coolant manifolds without modifications, and the plain shaft is protected by a contact seal that retains lubrication when the motor is mounted either horizontally or vertically.
