Product Description:
The MSK040C-0450-NN-S1-UP0-NNNN servo motor is manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a permanently excited synchronous unit, it is intended to operate with IndraDrive amplifiers and deliver precise rotary motion in conveyor indexing tables, pick-and-place heads, and compact tool changers. By combining high-resolution feedback with a keyed output shaft, it provides repeatable torque transmission and accurate positioning in compact automation systems. This makes the motor useful on short-cycle equipment where repeatability and quick settling are more important than large frame size.
The motor uses natural convection to transfer heat from the stator to the surrounding air, eliminating external fans and simplifying ventilation requirements. It has a standard design housing, so mounting dimensions follow the common MSK outline used for this motor family. The motor has a size 040 frame and a length C housing, which helps machine builders plan space on tightly packed axes. A keyed output shaft supports positive torque transmission, and the motor is supplied without a holding brake, which lowers inertia when static load holding is not needed. Because cooling is passive, the motor can be installed in spaces where additional airflow hardware would be undesirable.
The motor uses winding code 0450 for its electrical configuration. Feedback comes from an optical single-turn encoder with 128 signal periods, and the data is transmitted through the Hiperface digital interface for direct compatibility with matching drives. Power and feedback connections are routed through a 240° rotatable connector, allowing the cable outlet to be aimed away from nearby machine parts after installation. This connection arrangement also helps keep cable routing orderly in crowded machine layouts. The optical encoder provides clear signal edges, and the single-turn arrangement reports absolute position within one revolution for accurate startup behavior and straightforward axis integration.
