Product Description:

The MSK101E-0300-NN-S2-BG0-RNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It supplies rotational power to positioning axes, gantries, and other motion stages that rely on closed-loop control for repeatable throughput. By combining sealed construction with integrated feedback, the motor supports the positional accuracy and durability required in automated assembly cells and material-handling equipment. This configuration is suited to applications that need precise speed control, stable positioning, and dependable operation during repeated motion cycles.

Thermal energy leaves the housing by natural convection, so no auxiliary fan or liquid circuit is needed. Position feedback is transmitted through an EnDat2.1 digital interface, which reports rotor angle from an internal measuring system with 2048 signal periods. The enclosure has an IP65 rating, which helps protect internal components from dust and low-pressure water jets on industrial equipment. Continuous operation is permitted in ambient temperatures from 0–40 °C. A B-side power connector keeps the stator cable on one side of the motor, and winding code 0300 matches the electrical characteristics expected by compatible drive settings.

The encoder uses optical scanning in a single-turn layout, so one mechanical revolution is measured without a multiturn counter. The motor has frame size 101 with length code E, which sets the active stack dimensions and supports the torque and inertia level of this housing. Torque is transmitted through a plain shaft, which is intended for direct coupling to the driven mechanism. The motor does not include a holding brake, so the axis must be secured by external braking or clamping when power is removed. The winding insulation uses thermal class F, which corresponds to class 155 insulation.
