Product Description:

The MSK071D-0300-NN-S3-UP0-NNNN is a servo motor manufactured by Bosch Rexroth Indramat and supplied in the MSK IndraDyn S Synchronous Motors series. As a drive element, it converts electrical commands from a compatible controller into controlled rotary motion for positioning duties in automated machinery. This type of motor is commonly used on packaging, printing, and material-handling equipment where stable speed and repeatable axis movement are required. The unit uses size 071, length D, and winding code 0300, which place it in a medium-torque frame for matched drive applications.

Cooling is provided by natural convection, so heat is removed by air moving around the housing without auxiliary fans or liquid circuits. The housing has an IP65 protection rating, which keeps out dust and resists low-pressure water jets during normal industrial use. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, and operation above that range requires derating. Torque is transmitted through a shaft with keyway, which supports secure coupling to pulleys, gears, or similar driven elements. The motor size is 071, giving the unit a consistent flange and bolt pattern for installation on compatible machine layouts.

Position data are returned through the Hiperface interface by a single-turn encoder that provides 16 signal periods per revolution. The encoder uses a capacitive scanning principle, which offers good resistance to vibration in industrial service, and the encoder plug can be rotated 240 degrees to simplify cable routing in tight spaces. The windings use thermal class 155, which suits the motor's self-cooled design and normal thermal load. The motor is supplied without a holding brake, so any required load retention at standstill must be provided by the machine or drive system.
