Product Description:

The MSK100A-0300-NN-S3-BP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In automated production lines, it converts drive amplifier current into tightly regulated rotary motion, allowing machine axes to accelerate, decelerate, and hold position with high repeatability. This operating behavior suits positioning axes, transfer systems, and other motion tasks that require stable speed control and accurate stopping. As a synchronous servo motor, it can respond quickly to command changes during repeated start-stop cycles.

Heat from the stator windings is removed through natural convection, so the motor can be mounted without external fans while still operating in a sealed housing. Its die-cast enclosure carries a protection rating of IP65, which helps keep out dust and low-pressure water jets encountered in washdown or machining cells. All electronic and mechanical components are intended to function across 0–40 °C, matching common machine environments. Power conductors are routed on side B, which can simplify cable routing when the unit is installed on right-hand machine walls. Mechanical torque is transferred through a shaft with a keyway, and the key helps prevent slip during cyclic load reversals on indexing tables or roll feeds.

Position data is returned to the drive via the Hiperface interface, and that signal is produced by a capacitive sensor system that tolerates vibration without relying on optical disks. This arrangement lets the matching drive monitor rotor position continuously for commutation and closed-loop motion control. Feedback is limited to a single-turn range with 16 signal periods, which is suitable for short-stroke axes that do not need multi-turn tracking. The winding insulation is class 155, allowing winding temperatures up to 155 °C before insulation life is affected. The motor uses the A-length frame, size 100 stator laminations, and winding code 0300 for its electromagnetic layout. It is supplied without a holding brake, so stopping torque must be provided by the drive or by external mechanical hardware.
