Product Description:

The MSK101E-0300-FN-M1-AG3-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In closed-loop motion systems, this motor supplies regulated torque and precise position data, allowing automated axes to accelerate, decelerate, and hold target angles within narrow tolerances during continuous production cycles. This role suits automated equipment that depends on repeatable axis movement and stable feedback during long operating periods. The motor uses the standard mechanical design code, has frame length E, and carries the 0300 winding set for medium-voltage drives.

Its liquid cooling circuit removes stator heat through an external coolant loop, so full current can be maintained even inside sealed machine frames where airflow is limited. Position data is exchanged through a Hiperface interface, and this channel carries both incremental and absolute information to the drive controller. An internal encoder with an optical scanning method generates 128 signal periods, which the electronics interpolate for smooth velocity control and steady low-speed operation. Because the encoder uses a multiturn absolute format, the controller can track shaft position across many revolutions without requiring a homing routine after every restart.

An electrically released holding brake supplies 120 Nm of static torque, keeping vertical loads secure when power is removed. The housing is built in Motor Size 101, which provides a large rotor diameter while remaining compatible with common MSK mounting flanges. The output uses a plain shaft, so torque is transferred directly through rigid couplings or shrink discs without keyway backlash. All power conductors exit on the A-Side of the stator, which helps simplify cable routing in line-mounted cabinets and other tightly arranged machine layouts.
