Product Description:
The MSK101E-0300-NN-M1-BG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for precision position and speed control in automated machinery, providing closed-loop feedback and a compact construction that support fast cycles, repeatable motion, and stable control response in industrial automation. This model is suited to servo axes that need accurate start-stop behavior, smooth speed changes, and dependable positioning across frequent production cycles. The motor has a standard design with no special coatings or bearing arrangements.
The motor relies on natural convection for heat dissipation, so enclosure airflow paths must remain unobstructed during installation. Its winding uses Winding code 0300, a configuration selected to balance torque output with drive current in mid-power motion axes. The frame is Motor size 101, which fits larger mechanical interfaces while remaining within the standard MSK footprint. Axial depth corresponds to Motor length E, which increases continuous torque without changing the mounting pattern. The larger frame supports installation on machine sections that need higher torque capacity while preserving compatibility with the series mounting envelope. A plain shaft provides backlash-free coupling to gearboxes or belt pulleys, and the power connector is positioned on the B-side to simplify cable routing in installations with right-hand service access.
Position feedback is provided by a Hiperface interface that uses optical scanning and resolves rotor position into 128 signal periods per revolution. The encoder also has a multiturn absolute feature, so shaft revolutions are tracked without external batteries and absolute position data remains available to the drive after rotation over multiple turns, which helps restore position information after restart. The motor is supplied without a holding brake, so any power-off load support must come from drive torque or an external mechanical locking device.
