Product Description:
The MSK101E-0450-NN-S2-AG0-RNNN belongs to the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is an IndraDyn S synchronous servomotor intended for closed-loop positioning on packaging lines, printing machinery, and handling modules where electronic drives require accurate torque and speed control. The motor is suited for coordinated axes that need repeatable motion during frequent starts, stops, and load changes. That operating profile suits synchronized motion tasks where accurate response is needed over long duty cycles.
This motor dissipates heat by natural convection, so no external fan or liquid circuit is required and cabinet airflow remains uncomplicated. Feedback is transferred through the EnDat2.1 interface, allowing the drive controller to receive absolute position data and electronic nameplate information through a single serial channel. The encoder provides 2048 signal periods, which the drive can interpolate for high-resolution motion control. The unit is supplied without a holding brake, so static load retention must come from the drive or an external clamping device. With frame size 101, the motor uses the stator diameter and mounting pitch associated with that housing. The output is a plain shaft for direct coupling to gearboxes, pulleys, or rigid couplings. The motor also uses single-turn feedback, winding code 0450, length code E, and a power connection on the A side.
The rotor and housing are machined to an increased concentricity tolerance, which helps reduce cogging torque and supports smoother velocity control. An optical scanning principle inside the encoder helps maintain low jitter after repeated thermal cycles, which is useful for precise contouring in multi-axis systems. The power connector is oriented on the A-side, keeping motor cabling parallel to the machine bed and leaving the drive end clear for mechanical integration. This cable orientation can also simplify routing in compact equipment where available space around the motor face is limited.
