Product Description:

The MSK030C-0900-NN-M1-UP1-NSNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed control in automated machinery, where the integrated encoder supplies feedback to the drive controller for accurate motion regulation. Its compact frame allows installation in tight mechanical envelopes, which is useful on axes with limited mounting space or restricted access around adjacent machine parts. Because the motor combines power generation and position feedback in one housing, it supports compact servo axes in feeders, pick-and-place units, and small transfer mechanisms.

Heat is removed through natural convection, so no external fan or liquid circuit is required. Digital feedback travels over the Hiperface interface, and the optical encoder provides 128 signal periods per revolution for interpolation by the controller. The motor uses size code 030, which places it in the smallest frame range of the MSK family. Winding code 0900 corresponds to the electrical characteristics expected by compatible IndraDrive amplifiers. A rotatable 240° M23 encoder connector helps route the feedback cable in confined machine layouts and keeps bend direction flexible near panels or guarding.

The encoder is a Multiturn Absolute device, so shaft position is retained through power loss and the axis can restart without a homing cycle. An electrically released holding brake provides 1 Nm of static torque to secure light vertical or indexing loads when power is removed. The motor uses build length C, which keeps axial space low while providing the active stack length assigned to this version. Torque is transmitted through a shaft with keyway, allowing positive engagement with pulleys or couplings. Optical scanning inside the encoder head reduces mechanical wear during long-term operation.
