Product Description:

The MSK101E-0300-FN-M1-AG2-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automation cells, it converts the regulated electrical output of an IndraDrive controller into controlled rotary motion suited for positioning tables, gantries, or packaging shafts. The motor is intended for axes that need precise speed and position control during repetitive motion, especially where compact installation space and stable closed-loop operation are important. That operating profile suits pick-and-place systems, handling equipment, and process machinery that run with frequent starts, stops, and direction changes.

The motor’s thermal management is based on liquid cooling, a closed-loop coolant jacket that removes stator heat and satisfies the FN cooling requirement listed in the type code. Position data is returned through a Hiperface interface, allowing the drive to process feedback information with high accuracy during motion. The feedback system supports stable commutation and position tracking across the normal operating range. Inside the encoder, an optical disk delivers 128 signal periods, providing fine interpolated resolution for tight velocity control and smooth regulation at low speed. Because the sensing system is multi-turn absolute, power-on homing cycles are eliminated after shutdown or restart. An electrically released holding brake supplies 70 Nm of static torque so loads remain secured when power is removed.

The mechanical side follows the standard design variant with a plain shaft, which avoids the stress concentrations associated with a keyway in high-speed couplings. The shaft format also supports direct coupling arrangements where a keyed connection is not required. Frame size 101 and motor length code E pair with winding code 0300 for medium-inertia drive tasks that require steady torque response. The power connector is oriented on the A-side, which helps route motor leads away from coolant hoses and keeps the cable exit arrangement straightforward. This layout is useful in machines where the motor must fit beside hoses, guards, or other tightly spaced components.
