Product Description

MSK071E-0300-NN-S1-UG0-NNNN is a servo motor. It is designed and developed by Bosch Rexroth. The motor has a plain shaft that provides a non-positive shaft-hub connection for excellent running smoothness. Operators can use clamping sets, clamping sleeves or elements to couple the motor to the machine elements. The motor is designed for convection cooling. The heat is dissipated via natural convection to ambient air and via heat conduction to the machine. The optimal ambient air temperature is 0 to 40 degrees Celsius. Temperatures between 40 and 55 degrees Celsius lead to output derating. Bosch does not allow MSK motor use at temperatures above 55 degrees. MSK motor temperature is monitored through an integrated temperature sensor built into the stator. Attached control devices monitor functioning of the temperature sensors.

The MSK071E-0300-NN-S1-UG0- NNNN does not include a holding brake. However, brakes are available as options and can be ordered if required. The encoder on the motor is a singleturn encoder with 7 to 12 Volts supply range and maximum 60 milliamps draw. A 240-degree rotatable power connection provides installation flexibility. Continuous torque at standstill for the MSK071E-0300-NN-S1-UG0-NNNN motor is 23 Nm. The continuous current at standstill is 12.5 Amps. The maximum torque and current output of the motor are 84 Nm and 56.3 Amps. Torque constant of the motor is 2.05 Nm/A at 20 degrees Celsius. The voltage constant is 126.4 Volts per 1000 RPM. Resistance for the motor windings is 0.79 Ohms at 20 degrees Celsius. The inductance of the motor windings is 5.9 millihenry. Maximum speed of the servo motor is 4200 RPM. The motor protection rating is IP65. Weight of the motor is 23.5 kilograms.
