Product Description:

The MSK101E-0450-NN-M1-AG3-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. With motor size 101 and length code E, this standard-design unit serves as a direct-drive element for positioning or velocity loops in conveyors, gantries, and packaging lines. It is intended for use with a compatible drive controller that regulates torque, speed, and position during axis movement. The winding code 0450 indicates its electromagnetic configuration, and the power connector is located on the A-side for straightforward cabinet wiring. This arrangement suits applications that need repeatable starts, stops, and speed changes throughout normal machine cycles.

Heat generated in operation is dissipated by natural convection, so no external blower is required and the IP65 enclosure can remain fully sealed. The aluminum housing shields the internal windings against dust ingress and low-pressure water jets, permitting installation close to process equipment. A plain shaft transmits torque directly to couplings or belt pulleys, and its surface finish helps minimize fretting in rigid couplings. Rated performance is maintained at ambient temperatures from 0 to 40 °C; outside this range, derating is required. The windings use insulation class 155, allowing continuous-duty operation at elevated internal temperatures. Because cooling is passive, surrounding airflow requirements remain simple in enclosed machine areas.

Position feedback is delivered through a Hiperface optical encoder that produces 128 signal periods per mechanical revolution. This feedback supports commutation and closed-loop position control across the operating speed range. The encoder uses a multi-turn absolute scanning system, so the drive controller can read stored position data immediately after power-up. Absolute position retention reduces the need for a homing cycle after power restoration. An electrically released holding brake is integrated, and when energized it supplies 120 Nm of static torque to keep vertical loads stationary during downtime or emergency stops. The standard mechanical layout keeps the cable exit on one end, which helps simplify installation in compact machine assemblies.
