Product Description

The Bosch Rexroth MSK103B-0300-NN-S1-UG1-NNNN is a servomotor. It is used in combination with a drive controller. Areas of use and application for the motor include robotics, metal forming machines, printing machines and paper processing machines. The motor features a singleturn absolute encoder with 128 signal periods. The interface on the encoder is Hiperface. The current consumption of the encoder can go up to 60 milliamps. The supply voltage range for the encoder is 7 to 12 Volts DC. The function of the encoder is to provide feedback to the connected drive controller. Singleturn encoders can provide the feedback within one rotation of the motor shaft. The feedback and power connectors on the MSK103B-0300-NN-S1-UG1-NNNN are 240-degree rotatable. The motor also features a holding brake with 33 Nm holding torque. The rated voltage for the brake is 24 Volts DC.

The maximum connection and disconnection times for the holding brake on the MSK103B-0300-NN-S1-UG1-NNNN are 40 milliseconds and 270 milliseconds. The motor shaft is smooth and is fitted with a sealing ring. The seal on the motor shaft performs two important functions: prevention of dust and moisture ingress and prevention of oil leakages. The use of a shaft seal improves the operating lifespan of the MSK103B-0300-NN-S1-UG1-NNNN motor. However the seal degrades due to wear and requires periodic replacement. The MSK103B-0300-NN-S1-UG1-NNNN cools via natural convection. The ambient temperature recommended by Bosch for motor operation is 0 to 40 degrees Celsius. The site altitude recommended by Bosch for motor operation is 0 to 1000 meters. The performance specifications of the MSK103B-0300-NN-S1-UG1-NNNN motor are valid for ambient conditions that are recommended by Bosch. Operation of the motor outside these conditions is not recommended.
