Product Description:

The MSK101E-0450-FN-M1-BG2-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This rotary unit converts drive current into precisely regulated torque and speed so that conveyor axes, tool spindles, or gantry joints can follow programmed motion profiles with minimal position error. Its design supports use with compatible Rexroth drive controllers that monitor current, temperature, and position feedback, allowing stable closed-loop control during frequent starts, stops, and direction changes in continuous production equipment. This makes the motor suitable for coordinated motion tasks where smooth speed regulation and repeatable positioning are required over long operating periods.

The motor uses liquid cooling to draw heat away from the stator, allowing full continuous torque without external fans and helping thermal conditions remain stable during demanding duty cycles. An electrically released holding brake provides 70 Nm of static torque so vertical loads can remain in place when power is removed. The housing is sealed to IP65, which helps keep dust and low-pressure water jets away from internal parts. Position data are exchanged over the Hiperface interface, and the optical encoder generates 128 signal periods per mechanical revolution for responsive speed loops and accurate rotor-angle tracking. Liquid heat removal also avoids adding fan airflow at the motor body, which can help in enclosed installations where air movement is limited.

The encoder stores position as a multiturn absolute value, so the drive can retain shaft position information through power cycles without a homing routine at every restart. Operation is permitted at ambient temperatures from 0–40 °C, which suits typical enclosed industrial machinery. A plain shaft transmits torque directly to a coupling and avoids the stress concentration associated with a keyway in some applications. The plain output end is also straightforward to pair with clamping hubs and similar transmission elements used on precision servo axes. Thermal endurance corresponds to insulation class 155, and the motor also has frame size 101, an E-length stator, standard mechanical design, winding code 0450, and a power connector on side B that helps route cables toward the rear of the machine structure.
