Product Description:

The MSK101D-0300-NN-S1-LP2-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts drive current into controlled rotary motion for axes that require accurate speed and position regulation in packaging, handling, and machining equipment. Motor size 101 and length code D place it in a mid-frame category that suits medium-duty servo applications. Its standard design and 0300 winding support use with compatible drive stages, allowing predictable torque response and stable closed-loop motion during repeated starts, stops, and speed changes.

Thermal management for the unit is classified as FN and relies on natural convection, so heat dissipates through the housing without auxiliary blowers. Position feedback is delivered through a Hiperface encoder that provides 128 signal periods per electrical revolution. The sensing head uses optical scanning and is configured as a single-turn device, which supplies absolute position information within one mechanical turn before rollover. This feedback arrangement supports stable commutation, smooth low-speed operation, and accurate position correction when the load changes during motion.

An electrically released holding brake supplies 70 Nm of static torque, preventing axis movement when the drive is disabled or during an emergency stop. Output torque is transmitted through a shaft with a keyway, which provides positive mechanical engagement with pulleys or couplings during acceleration and deceleration. The power connector exits on the motor’s left side, which can simplify cable routing when machine wiring runs along that direction. This combination of brake, shaft, and connector layout supports use on both vertical and horizontal axes where secure load holding and orderly cable placement are important.
