Product Description

The MSK050B-0450-NN-M2-UG0-RNNN is a synchronous servo motor. It is designed and developed by Bosch Rexroth. Product line to which the motor belongs is MSK. The motor includes an integrated multiturn optical encoder with EnDat 2.1 interface and 2048 signal periods. The encoder accuracy is ±20 angular seconds. The peak current consumption of the motor encoder is 250 milliamps. The motor encoder requires 3.6 to 14 Volts DC supply input. A holding brake is not available on the MSK050B-0450-NN-M2-UG0-RNNN motor. The smooth motor shaft includes a sealing ring. The seal on the shaft protects motor bearings and is one of the factors that contributes to the IP65 protection rating of the motor housing. The shaft seal prevents leakage of motor oil and also prevents ingress of dust and moisture from the operating environment.

The importance of the shaft seal is increased since the MSK050B-0450-NN-M2-UG0-RNNN is usually mounted outdoors because of its IP65 rating. However the seal does suffer wear and requires periodic replacement. Maintenance of the motor by trained personnel helps to ensure that the motor performance stays in line with manufacturer specifications. Motor maintenance also helps to increase the operating lifespan of the motor. The connectors on the motor are 240-degree rotatable. Ambient specifications for the MSK050B-0450-NN-M2-UG0-RNNN include 0 to 40 degrees Celsius operating temperature and altitudes of 0 to 1000 meters above mean sea level. If the specified ambient limits are exceeded, the performance data of the motors must be reduced. The motor can be operated with derating at altitudes reaching 3000 meters and temperatures reaching 55 degrees Celsius. The MSK050B-0450-NN-M2-UG0-RNNN cools through natural convection. The approximate weight of the MSK050B-0450-NN-M2-UG0- RNNN is 5.4 kilograms.
