Product Description

The Bosch Rexroth MSK070E-0450-NN-M1-UG1-NSNN is a servo motor with standard and extended design. As per the MSK070 series type code, the motor frame size is 070 and the motor frame length is E. The code for the motor winding is 450. Every MSK motor has a number of components that include a shaft, a stator with winding, bearings, encoder and an optional holding brake. The MSK series includes motors with shafts that are plain or shaft with a keyway. The MSK070E-0450-NN-M1-UG1-NSNN motor has a plain shaft. The shaft includes a sealing ring. The seal on the motor shaft helps to protect internal motor components against contaminants – such as dust and moisture – that may be present in the operating environment. The shaft is also a factor that contributes to the IP65 protection rating of the motor. This rating allows use of the MSK070E-0450-NN-M1-UG1-NSNN motor is adverse environmental conditions.

The MSK070E-0450-NN-M1-UG1-NSNN also features an optical multiturn absolute encoder rated for 128 signal periods. An optional holding brake rated for 23 Nm is part of the motor package. The brake operates according to the electrical release principal and prevents motor shaft rotation at standstill. It is a safety feature that is used to prevent accidents caused by accidental motor shaft movement. The cooling method for which the MSK070E-0450-NN-M1-UG1-NSNN is designed is natural convection. This cooling method relies on flow of ambient air over the operating motor. Proper heat dissipation requires appropriate inter-device spacing. Forced air cooling can also be used if required. The working temperature range, according to the product documentation, is 0 to 40 degrees Celsius. The power and feedback connectors on the MSK070E-0450-NN-M1-UG1-NSNN are 240-degree rotatable.
