Product Description:

The MSK101E-0300-FN-M1-AP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This standard-design unit combines high torque density with precise electronic feedback. It is intended for automated axes that require accurate speed regulation and repeatable positioning in packaging lines, metal-cutting centers, and material-handling modules.

This motor relies on liquid cooling that circulates through the stator jacket to stabilize winding temperature under continuous duty. A protection rating of IP65 seals the housing against dust ingress and low-pressure water jets, so no additional enclosure is required in most plant areas. The rotor carries a keyed shaft, described as a shaft with keyway, allowing rigid power transmission into pulleys or couplings. For applications where passive mechanical holding is handled elsewhere, the unit is supplied without a holding brake. Mains power enters through an A-side power connector, which positions the cable outlet toward the drive end and aids compact cabinet layouts. Mechanical sizing follows the 101 frame with length code E, while winding code 0300 sets the electromagnetic characteristics for medium-inertia loads.

Motion feedback is delivered through a Hiperface interface that carries combined power and data on a single hybrid cable. The optical reader processes a scale of 128 signal periods per revolution, and its multiturn absolute capability reports up to 4096 mechanical turns without battery backup. Combined with an operating ambient range of 0 to 40 °C, the encoder allows precise position recovery after power cycles. Thermal endurance is ensured by an insulation class 155 system that protects the windings against hot-spot temperatures during overload events. This arrangement is useful on axes that must resume motion without a separate homing routine after a shutdown.
