Product Description:

The MSK071E-0450-FN-M1-AG2-NNAN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact drive element, this motor converts commanded current from a drive controller into precise mechanical rotation for axes that demand high positional accuracy in industrial automation. It uses a plain output shaft to couple directly with gearboxes or load-side couplings, while the reduced runout design helps limit radial deviation during rotation. This layout supports accurate positioning on packaging, handling, and machining equipment, especially in applications with repeated starts, stops, and direction changes.

The motor has size 071 and length code E, and its stator winding uses code 0450, a combination that sets torque and voltage constants for compatible IndraDrive amplifiers. Process heat is removed by liquid cooling, and the FN code indicates that coolant flows through the integrated jacket for continuous duty. Rotor position is measured with an optical encoder that supplies 128 signal periods per mechanical revolution over the Hiperface interface, allowing fine velocity feedback at the drive. An electrically released holding brake supplies 30 Nm of static torque so vertical or suspended axes remain stationary during power loss. Power cabling is routed on the A-side of the housing, which helps simplify parallel mounting inside multi-axis assemblies.

The encoder provides multi-turn absolute feedback for tracking up to 4,096 revolutions, which removes the need for homing after shutdowns. The aluminum frame has an IP65 rating that helps protect internal windings from dust ingress and low-pressure water jets, and its insulation system is certified for class 155 thermal endurance. Specified ambient operation spans 0 to 40 °C, and operation above this range requires derating of the continuous current to limit thermal loading. This motor is commonly used on coordinated servo axes in automated transfer lines and similar machinery.
