Product Description

The Bosch Rexroth MSK071D-0450-FN-S1-UG0-NNNN is a MSK series synchronous servo motor. It is well suited to industrial applications such as machine tools, robotics, metal forming machines and food processing machines. It is deployed with a drive controller that provides power to the motor and controls motor speed and torque. The MSK071D-0450-FN-S1-UG0-NNNN is a liquid cooled motor. It operates optimally at 0 to 40 degrees Celsius ambient temperature. The continuous torque at standstill for 60K overtemperature is 33.3 Nm. The continuous current at standstill for 60K overtemperature is 30.3 Amps. The maximum torque rating for the MSK071D-0450-FN-S1-UG0-NNNN is 66 Nm. The maximum current rating is 69.3 Amps. Torque constant for the motor at 20 degrees Celsius is 1.25 Nm/A. The motor voltage constant at 20 degrees Celsius is 77.1 Volts/1000 RPM.

The inductance of the windings on the MSK071D-0450-FN-S1-UG0-NNNN is 3.2 millihenry. The leakage capacity of the components is 7.8 nanofarads. The moment of inertia of the motor rotor is 0.00230 kg m². The thermal time constant is 6 minutes.  Maximum speed rating of the servo motor is 6000 RPM. The sound pressure produced by the motor during operation is always less than 75 dB. The MSK071D-0450-FN-S1-UG0-NNNN does not feature a holding brake. Bosch does provide optional holding brakes for MSK motors, and one can be ordered separately if required. The integrated encoder is a singleturn optical encoder that supports Hiperface. The encoder is rated for 128 signal periods. The shaft on the motor is plain. The shaft includes a sealing ring. The protection rating of the MSK071D-0450-FN-S1-UG0-NNNN is IP65. Both connectors on the motor are 240-degree rotatable. Housing of the MSK071D-0450-FN-S1-UG0-NNNN has a standard design.
