Product Description:

The MSK100C-0450-NN-M1-BP0-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and velocity control on machine tools, packaging lines, and handling axes where accurate torque delivery and compact installation are required. By combining precise encoder feedback with a compact mechanical layout, the motor allows drive systems in industrial automation to achieve consistent motion profiles without external gear reduction. This operating concept supports repeatable starts, stops, and speed changes during cyclic machine operation.

Passive heat removal by natural convection lets the housing shed thermal energy without fans or liquid circuits, simplifying cabinet design and reducing maintenance. The integrated feedback device communicates through the Hiperface interface so that the controller receives absolute position and commutation data over two differential channels. Position data are obtained from a scale that provides 128 signal periods per mechanical revolution, giving the drive fine resolution for smooth speed and torque loops. Signal generation relies on optical scanning, which has no mechanical wear points and maintains long-term accuracy. The encoder is a multi-turn absolute type, so rotor position remains available over multiple revolutions even after power loss and startup does not require a homing move.

Size code C denotes the third-longest stator length in the frame class, increasing continuous torque while preserving the bolt circle associated with frame size 100. Power is transmitted through a shaft with a keyway, ensuring positive engagement with couplings or pulleys during load changes. Winding identifier 0450 matches the motor to drives that can supply its rated current and voltage, while the lack of a holding brake means static loads must be secured by the drive or by an external clamp. The motor uses a standard housing design with a B-side power connector, allowing cables to be routed to the right for flexible installation in control cabinets.
