Product Description:

The MSK100A-0300-NN-S1-AG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a standard-design actuator with motor size 100 and the compact A-length stator, it is installed where precise rotary motion must be produced for positioning tables, packaging axes, or tool spindles. The part is supplied without a holding brake, so machines that must retain position after power-off need an external mechanical lock or drive torque.

Its cooling relies on natural convection, a method that transfers heat from the frame to surrounding air without forced airflow. This simplifies enclosure layouts but requires unobstructed ambient circulation. An IP65 protection rating keeps dust out and withstands low-pressure water jets, allowing direct mounting in production areas. Position feedback is delivered through a Hiperface interface, giving the drive digital absolute data over two shielded conductors. Inside the encoder, an optical scanner reads 128 signal periods, so the drive can interpolate fine angle increments for smooth velocity control. Its low jitter works with single-turn tracking to maintain accuracy during one full revolution, while the power connector located on the A-side supports cable routing in top-entry control cabinets.

The motor operates in ambient temperatures from 0–40 °C, matching typical control cabinet climates without derating. Class 155 insulation allows winding temperature to rise well above room level before thermal limits are reached, supporting high-cycle duty. A plain shaft transmits torque through a clamping coupling or shrink disc, eliminating the need for a keyed shaft end. Electrical behavior follows winding code 0300, which matches the resistance and inductance values expected by compatible IndraDrive controllers. These characteristics support reliable motion sequences, while the aluminum frame helps simplify mechanical alignment within modular machine frames.
