Product Description:

The MSK100A-0450-NN-M1-AG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It supplies precisely controlled torque for automated machinery, and when paired with a compatible drive it performs positioning, speed control, and cyclic motion duties on packaging lines, gantries, and machine-tool axes. Its synchronous design supports responsive speed regulation and repeatable motion during rapid indexing and coordinated axis movement. The standard configuration uses motor size 100, length code A, and winding code 0450.

This unit is cooled by natural convection, so heat is removed through the housing surface without external fans or a blower. Feedback is handled through a Hiperface interface that carries position data and stored motor information, while the optical scanning system resolves rotor position over 128 signal periods per revolution. The encoder uses multi-turn absolute technology, allowing the drive to recover the exact shaft angle after power loss without an immediate reference move. A protection rating of IP65 seals the motor against dust ingress and low-pressure water jets, which supports mounting near the work zone. The motor is intended for operation in ambient temperatures from 0 to 40 °C.

The mechanical interface uses a plain shaft that fits couplings or pulleys without a key, which can help reduce alignment errors in high-precision motion systems. It is supplied without a holding brake, so static load retention must come from the drive or an external brake module when the axis is stopped. Power is routed through an A-side power connector, which can simplify cable runs on machines that direct conduit to that face. Thermal endurance is supported by insulation class 155, permitting winding temperatures up to 155 °C before insulation damage becomes a concern.
