Product Description

MSK075E-0300-NN-S2-UG1-RNNN is a digital servo motor. Bosch Rexroth produces the motor for industrial and commercial applications. The motor forms part of a servo system that includes a servo controller. The controller provides electrical power for the motor and controls motor parameters including speed, torque and position. Continuous torque at standstill, also known as zero speed torque or starting torque, refers to the amount of torque a motor can produce when it is not spinning (at standstill) and when it is continuously supplied with power. This is an important characteristic of a motor, as it determines the ability of the motor to start a load and overcome any initial resistance. The continuous torque of the MSK075E-0300-NN-S2-UG1-RNNN motor depends on operating conditions and is limited by the cooling method. The continuous torque at standstill with convection cooling is 21 Nm and with surface cooling is 32.1 Nm.

It is important to note that the continuous torque at standstill is different from the running torque, which is the torque that the motor can provide while it is running at a certain speed. The running torque is typically lower than the continuous torque at standstill, because the motor is designed to produce more torque at standstill to overcome the initial resistance of a load, and less torque when it is running at a steady state. Maximum speed rating of the MSK075E-0300-NN-S2-UG1-RNNN motor is 5200 RPM. The sound pressure level produced during operation is always less than 75 dB.  The singleturn optical encoder on the motor has an EnDat 2.1 interface. The flexible power connector allows 240-degree rotation. The MSK075E-0300-NN-S2-UG1-RNNN motor has a smooth shaft with a seal. Housing of the motor features reduced run out and increased concentricity.
