Product Description:
The MSK101D-0450-FN-S1-AP0-NNNN servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts drive current into controlled rotary motion for axes that need rapid acceleration and repeatable positioning in automated machinery. When paired with a compatible drive, it supports accurate speed control and positioning on handling, packaging, and other motion-intensive equipment.
For thermal management, the motor relies on liquid cooling, so heat from the stator windings is removed through a coolant circuit instead of ambient air. Position feedback is handled through the Hiperface interface, which carries incremental and absolute encoder data between the motor and the drive. The integrated encoder resolves shaft position into 128 signal periods per mechanical revolution, and its sensing principle is optical, which helps maintain precise signal quality. Because the scanner is a single-turn device, it reports absolute position within one revolution while higher-level position tracking is handled by the controller. Winding code 0450 sets the stator resistance and inductance, and the insulation system uses class 155 materials to withstand elevated copper temperatures during continuous duty. This version uses the standard design, so the mounting and housing dimensions follow the regular series layout.
The motor has a size 101 housing with length code D, giving it a compact format for medium-torque drive tasks. Torque is transmitted through a shaft with keyway, and the power and feedback connections exit on the A-side of the housing for straightforward cable routing. The housing is sealed to IP65, and the motor is supplied without a holding brake, so vertical loads require external holding force when power is removed. Continuous operation is permitted in ambient temperatures from 0–40 °C, which suits common machine-room conditions. The motor also uses liquid cooling rather than fan-based airflow, which helps maintain thermal stability in tightly packed machine layouts.
