Product Description:

The MSK100C-0450-NN-M1-BG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop drives where repeatable torque, compact dimensions, and integrated encoder feedback are required. These qualities help position tooling, conveyor sections, or pick-and-place axes with high accuracy in industrial automation environments.

The motor relies on natural convection, so heat leaves the housing through its ribbed exterior without the assistance of fans or liquid circuits, simplifying installation inside tight machine spaces. Feedback is exchanged through a Hiperface interface that transmits absolute position and electronic nameplate data to compatible IndraDrive controllers, and the optical sensor delivers 128 signal periods per mechanical revolution to support fine electronic commutation. Winding code 0450 corresponds to the electrical resistance and inductance used by the drive, while frame size 100 sets the IEC mounting footprint. The standard design housing and plain shaft accommodate couplings or gearheads without additional machining. Motor length C gives extra active stack for higher continuous torque compared with shorter variants.

The encoder’s sensing principle is optical, which ensures minimal drift over temperature and supplies a multiturn absolute position value so the controller retains rotor location after power cycles without homing. Power is supplied through a connector on the B-side of the end bell, allowing cables to exit opposite the feedback connector and easing routing inside cabinets. Because the unit ships without a holding brake, static axis locking must be provided by the mechanical system or the drive’s torque when power is present. The C-length stator, plain shaft, and standard housing suit medium-inertia loads that demand continuous duty with natural cooling.
