Product Description

MSK040C-0450-NN-S1-UG0-NNNN is a Bosch Rexroth servo motor. It is part of the MSK product line. The motor is equipped with an optical singleturn encoder with 128 signal periods. The maximum encoder speed is 12000 RPM. Peak current consumption of the encoder is 60 milliamps and the supply voltage range is 7 to 12 Volts DC. The encoder supports Hiperface protocol. The servo motor has a smooth shaft with a shaft seal. This seal provides robust ingress protection for reliable motor operation. The power connection on the MSK040C-0450-NN-S1-UG0-NNNN can be rotated 240 degrees. Bosch has designed the motor for convection cooling. The continuous torque at standstill is 2.7 Nm. The continuous current at standstill is 2.4 Amps. Peak torque and current specifications for the synchronous servo motor are 8.1 Nm and 9.6 Amps respectively.

Torque constant of the motor is 1.25 Nm/A at 20 degrees Celsius. Voltage constant of the motor is 76.7 V/1000 RPM. Windings on the servo motor have a resistance of 7.4 Ohms at 20 degrees Celsius. Inductivity of the motor windings is 37.9 millihenry. Discharge capacity of the components is 2 nanofarads. Number of pole pairs on the motor is four. The rotor?s moment of inertia is 0.00014 kg m2. Thermal time constant of the MSK040C-0450-NN-S1-UG0-NNNN motor is 16 minutes. The peak speed is 6000 RPM. Sound pressure level of the motor does not exceed 75 dB(A) during operation. Optimal operation is dependent on ambient temperature not exceeding 40 degrees Celsius. Bosch has provided MSK synchronous servo motors with an IP65 rated housing. This housing ensures robust ingress protection and allows MSK motor deployment in a wide range of operating conditions.
