Product Description:

The MSK101E-0300-FN-S1-AP2-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Intended for high-precision axes in industrial automation, the unit converts electrical energy into controlled rotary motion while feeding position data back to the drive controller. Its role is to supply tightly regulated torque and speed for packaging, handling, and machining centers that rely on coordinated multi-axis motion.

Thermal management is handled through liquid cooling, a requirement signaled by the FN designation. Coolant flowing through the stator jacket removes heat so the motor can deliver rated output even in compact cabinets that lack airflow. Feedback is provided through the Hiperface digital interface, and the encoder generates 128 signal periods per mechanical revolution; this fine spacing allows precise interpolation in the drive. Because the encoder is optical, it provides high resolution without mechanical wear. Its single-turn structure reports absolute position within one revolution, which simplifies homing routines. The housing uses the standard design, measures size 101 with length code E, and is fitted with an A-side power connector. Continuous operation is permitted from 0 °C to 40 °C, and winding code 0300 indicates the electrical parameters used with matching IndraDrive power stages.

Dynamic holding capability is supplied by an electrically released brake that produces 70 Nm of static torque, allowing vertical axes to maintain position when power is removed. The housing is rated IP65, protecting internal components from dust ingress and low-pressure water jets so the motor can be mounted near process equipment. The output uses a shaft with a keyway, providing positive torque transmission to couplings or pulleys without relying on frictional clamping. The motor uses insulation class 155, which permits winding temperatures up to 155 °C before insulation degradation.
