Product Description

Bosch Rexroth is known for manufacturing state-of-the-art products used in several industries. The MSK synchronous motors, designed to be used as rotary main and servo drive motors, are a group of these products. There are several motors in the series, and they differ from each other based on their driving powers and interfaces. They are also typically used in machine tools, printing and paper-processing machines, packaging and food-processing machines, metal-forming machines, and robotics.

The MSK070E-0300-NN-M3-UG1-NNNN in the MSK series is equipped with a plain shaft that provides a non-positive, zero-backlash shaft hub connection with a high degree of quiet running. It has two essential electrical connections: the power connection and the encoder connection. The power connection includes a connection for a temperature sensor which protects the motor from thermal overload. The motor is also equipped with a holding brake of 23Nm holding torque, which works with the electrically released principle. It holds the servo axis when the machine is de-energized. The connections and terminals between 5V and 50V on this motor are protective extra-low voltages, ensuring that they are protected from electric shock. The protective extra-low voltage system also allows for the connection of devices with basic insulation to extra-low voltage circuits.

The environmental conditions for optimal performance of the MSK070E-0300-NN-M3-UG1-NNNN are an ambient temperature of 40°C, relative humidity of 95%, and a setup height of 1000m. It is a self-cooling motor where heat is dissipated over natural convection into the ambient air and by heat conduction to the machine construction. Its degree of protection is IP 65; hence it is protected against damage from shock, penetration of dust, and water jets from different directions.
