Product Description
The Bosch Rexroth MSK050B-0450-NN-M1-UP1-NNNN is a MSK series servo motor. It has several integrated features that include a holding brake, encoder for feedback, shaft with keyway and rotatable connectors. The motor holding brake has a holding torque of 6 Nm. The brake is an electrically releasing brake. The optical motor encoder is a multiturn encoder with Hiperface interface and 128 signal periods. The feedback / power connectors on the MSK050B-0450-NN-M1-UP1-NNNN can be rotated 240 degrees. The main motor shaft features a keyway and a sealing ring. The purpose of the sealing ring is two-fold: prevent oil leakage and prevent ingress of materials that could damage the motor bearings. The shaft seal undergoes wear during motor operating and should be inspected periodically and replaced when required. Protection category of the servo motor housing is IP65.
This protection rating signifies that the motor is totally dustproof and is protected from low-pressure liquid jets. This allows motor installation outside control cabinets which helps to reduce capital expenditure. The installation near operating machinery also enables reduction in operational expenditure. The motor cools via natural convection and is designed for 0 to 40 degrees Celsius working temperature. The internal motor temperature is much higher than the ambient temperature. The ambient temperature recommendation helps to ensure that the internal temperature always stays below critical levels. The maximum operating speed of the MSK050B-0450-NN-M1-UP1-NNNN motor is 6000 RPM. The operating sound pressure level is always less than 75 dB. Weight of the MSK050B-0450-NN-M1-UP1-NNNN is approximately 5.4 kilograms. The thermal class of the motor is 155. Number of pole pairs on the MSK050B-0450-NN-M1-UP1-NNNN is 4. The surface of the motor is painted matte black.
