Product Description:

Bosch Rexroth Indramat manufactures the MSK100A-0300-NN-M1-AG1-NNNN as part of the MSK IndraDyn S Synchronous Motors series. The unit is an IndraDyn S synchronous servomotor intended to supply tightly regulated torque and speed for automated handling, packaging, and machining stations. In servo systems, it converts commanded current into controlled rotary motion so the drive can maintain consistent acceleration, speed regulation, and positioning accuracy during repeated machine cycles. It uses winding code 0300 and motor size 100, which gives it electrical characteristics suited to midsize servo axes. The motor length is A, so the housing remains compact while still fitting installations where mounting space is limited.

The housing carries a protection rating of IP65, which helps keep dust and low-pressure water jets away from internal windings during plant washdowns. Heat is removed through natural convection, so no fan or liquid circuit is fitted, and the motor relies on surrounding airflow and conductive mounting surfaces instead of auxiliary cooling equipment. Feedback is provided through a Hiperface optical encoder that delivers 128 signal periods per revolution and stores multiturn position data with an absolute reference. This arrangement gives the controller immediate position information after startup and supports accurate speed monitoring throughout the operating range. An electrically released holding brake rated at 32 Nm secures the load when power is removed, which is useful for vertical or indexing axes.

All connector terminations are on the A-side, which allows cable routing along one face of the machine frame. The output shaft is a plain shaft that mates with couplings or pulleys without a key, which can help reduce backlash sources in the drive train. A class 155 insulation system supports continuous winding temperatures when the ambient remains within the specified 0 to 40 °C range. The motor is often mounted on thermally conductive plates to help keep winding temperatures within the insulation limit while maintaining encoder accuracy and brake readiness.
