Product Description:

The MSK101E-0450-NN-M1-AG0-NNNN is a synchronous motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It operates as a closed-loop actuator that delivers commanded torque and speed to precision machinery, supporting positioning tasks in packaging stations, metal-cutting centers, and automated assembly lines where fast response and repeatability are required. Its synchronous design lets the drive regulate rotor position continuously, which supports accurate interpolation, repeatable indexing, and stable speed control during changing loads. The plain shaft simplifies coupling to gearboxes or direct-drive loads, while power is routed through an A-side connector that keeps cables on the same face as the feedback plug.

This model relies on natural convection for thermal dissipation, so no external fan or liquid circuit is needed. A protection rating of IP65 seals the housing against dust and low-pressure water jets, allowing cabinet-free mounting near the work zone. The mechanical frame uses motor size 101 with length code E and winding code 0450, which provides the torque-to-speed profile selected for this configuration. Internal conductors are insulated to thermal class 155 to tolerate higher winding temperatures during cyclic duty. Position information travels through the Hiperface interface, matching common Rexroth drive controllers. A standard design designation indicates that the motor is supplied without special coatings or auxiliary options.

The optical feedback system resolves rotation into 128 signal periods per turn, and its Optical scanning principle supports a multi-turn absolute count without battery maintenance. Because the motor is supplied without a holding brake, machines that must retain load force at power-off need an external brake or mechanical lock. The encoder’s multi-turn structure reports position over many revolutions, so restart behavior remains predictable after controlled shutdowns. Operation is intended within an ambient temperature range of 0 to 40 °C, and the feedback data helps the drive maintain accurate motion during repeated starts, stops, and position corrections.
