Product Description:

The MSK071E-0450-NN-M1-UP0-NNBN is an MSK IndraDyn S servo motor manufactured by Bosch Rexroth Indramat. As a synchronous drive element, it converts inverter current into controlled torque for positioning and speed duties in automated machinery and material-handling axes. The 071 frame size and E-length housing make it suitable for medium-power applications that need compact installation space and a sealed motor body. It is intended for machine axes that need repeatable motion, compact dimensions, and dependable operation during frequent start-stop cycles.

This motor is cooled by natural convection, so thermal energy is released through the housing surface without external airflow devices. For feedback, it uses a rotatable 240° connector that links an optical encoder with the Hiperface digital interface. The encoder provides 128 signal periods per mechanical revolution and supports multi-turn absolute position detection, so axis position remains available after power loss. A protection rating of IP65 helps protect the stator, connector, and bearings against dust ingress and low-pressure water jets. The rotatable connector also gives more flexibility when the motor must be installed near guarding, brackets, or adjacent drive components.

The mechanical output shaft is a shaft with a keyway, allowing rigid coupling to pulleys or gearboxes. Continuous service is permitted in ambient temperatures from 0 to 40 °C, which fits common factory and cabinet conditions. Insulation class 155 supports elevated winding temperatures during intermittent overloads. The motor is supplied without a holding brake, so any load-side position locking must be handled by the drive or by an external clamp. Its E-length housing and sealed layout are useful where mounting space is limited and cable routing must be adjusted around nearby machine components.
