Product Description:

The MSK101E-0200-NN-M1-LG2-NNNN is an IndraDyn S synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. In automated cells, this motor works with digital drives to deliver controlled torque and accurate positioning on axes that require repeatable motion. It is intended for servo axes in packaging, handling, and machine tool equipment where closed-loop motion must remain stable under changing loads. The unit uses winding code 0200 and a standard design, so it can be matched to compatible Rexroth controls in its intended operating range. Its E-length stator provides a longer active section for higher continuous output within the same frame family.

Thermal management relies on natural convection, and the note that cooling FN is required means the installation must leave enough free airflow around the housing. An enclosure rating of IP65 helps protect internal parts from dust and low-pressure water jets, which supports use near machining areas. The electrically released holding brake provides 70 Nm of static torque, so a vertical axis can remain in place when power is removed. Position data is transmitted through a Hiperface interface, and the optical encoder provides 128 signal periods per revolution for stable speed and position control. This combination supports accurate feedback and controlled stopping without adding separate external devices at the axis. A left-side power connector can also make cable routing easier when the drive is mounted on the motor’s right.

The encoder is a multi-turn absolute device, so the controller retains shaft position information across power cycles. That arrangement avoids the need to re-establish position after every restart in many closed-loop applications. Safe operation is supported in ambient temperatures from 0–40 °C, and the winding uses insulation class 155 for thermal endurance. Frame size 101 sets the motor’s mechanical envelope and helps determine the available mounting space around the axis. A plain shaft without a keyway is suited to friction-locked hubs and can help reduce runout in direct-coupled applications. This shaft form is commonly used with clamping hubs instead of keyed couplings.
