Product Description:

The MSK100B-0400-NN-S2-AP0-RNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Engineered as a compact drive for industrial automation, the unit converts electrical energy into controlled torque and speed for indexing tables, pick-and-place axes, and other servo-regulated machinery. Its role is to deliver repeatable motion profiles that integrate with Rexroth drive controllers and feedback networks used in modern production lines.

The motor relies on natural convection cooling, so its housing dissipates heat without auxiliary fans. A protection grade of IP65 seals the stator against dust ingress and low-pressure water jets, permitting installation close to process equipment. Precision feedback is supplied through an optical EnDat2.1 encoder, and the optical sensing tracks 2048 signal periods per mechanical revolution. Its single-turn format suits short-stroke axes that do not exceed one revolution. Increased concentricity in the rotor design minimizes runout, and the drive side uses a shaft with keyway for positive torque transmission to couplings or pulleys. The motor uses size 100 with length code B, which provides a favorable ratio between output torque and inertia.

The unit ships without a holding brake, so any vertical axis must use external clamping or dynamic drive torque to maintain position during power loss. Phase conductors terminate on the A-side, allowing cable routing that matches common control cabinet layouts. Thermal operation remains stable from 0–40 °C, and the insulation system is rated to class 155, supporting continuous winding temperatures associated with the 0400 winding code. This arrangement suits synchronized multi-axis systems that need accurate feedback, stable thermal behavior, and a direct mechanical drive connection.
