Product Description:

The MSK071E-0300-NN-M1-UG1-NSNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as the drive source for motion axes in automated packaging, material handling, and machine-tool equipment where high dynamic torque and precise positioning are required. The motor can be supplied in a standard version or in an explosion-protected version, allowing the same frame format to be used in general industrial areas or hazardous locations. This arrangement supports machine designs that need consistent installation dimensions across different operating environments.

Cooling is provided by natural convection, so the motor dissipates heat through its housing without requiring an external blower. The housing has an IP65 protection rating, which helps keep dust and water jets away from internal components. An electrically released holding brake supplies 23 Nm of braking torque to hold loads when power is removed. Continuous operation is permitted in an ambient temperature range of 0–40 °C. The motor has size code 071 and length code E, which indicate its frame dimensions. A rotatable connector with 240° adjustment helps simplify cable routing, and the internal feedback device provides 128 signal periods of base resolution to the drive controller.

Feedback performance is supported by an optical scanning system that transmits position data through the Hiperface protocol. The encoder is a multi-turn absolute unit, so it retains position information over multiple shaft revolutions without batteries. Thermal capability is supported by insulation class 155, which suits the winding system during sustained operation at elevated temperatures. This feedback arrangement allows the motor to report position accurately during repeated starts, stops, and reversals.
