Product Description:

The MSK101E-0450-NN-M1-BG3-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop motion control, it generates tightly regulated torque and speed in automated production lines, pick-and-place stages, and material-handling axes. This model pairs with Rexroth drive controllers through its digital encoder interface to provide precise position, velocity, and diagnostic feedback. Its feedback path helps the connected drive respond quickly to load changes during indexing and continuous-speed operation.

Cooling relies on natural convection, so the housing dissipates heat without external fans or liquid circuits. The winding code 0450 indicates the electrical characteristics used for this E-length rotor in the 101 frame size, and insulation class 155 supports continuous copper temperatures up to 155 °C. An electrically released holding brake provides 120 Nm of static torque, allowing vertical loads to remain locked when power is removed. Power is supplied through a connector on the B-side, which helps keep cabling routed along one machine edge. Motion feedback is obtained via the Hiperface serial interface. Its scanning head resolves 128 signal periods per revolution, and the optical sensor principle minimizes long-term drift.

The encoder stores absolute position across turns by using a multiturn absolute mechanism, so the axis can restart without a homing move after shutdown. A molded housing and shaft seal give the motor an IP65 rating that resists dust and low-pressure water jets common on processing lines. The drive end uses a plain shaft for coupling with clamping hubs or other friction-fit connections. The permitted ambient operating range is 0 to 40 °C, which matches common industrial enclosures and supports stable operation under self-cooling conditions.
