Product Description

Bosch Rexroth pays great attention to detail in the design of its factory automation units, including the MSK servo motors. They are synchronous motors in the IndraDyn S family typically used as rotary and servo main motors. Their prominent characteristics include compact build, high torque density, and precise encoder systems.

The MSK100B-0300-NN-S1-AG1-NNNN is a synchronous servo motor model in Bosch Rexroth’s MSK series. It is equipped with an optical encoder with a system accuracy of ±80 angular seconds and an Hiperface interface. This encoder detects the motor’s absolute, indirect position within one mechanical motor rotation and supplies the appropriate signals to the drive controller. It eliminates the need for separate incremental encoders and has a data memory where the motor’s parameters are stored. Hence, its start-up is quicker, and it can adjust safely to the drive controller. The motor’s nominal speed is 3,000 revolutions per minute, and it can generate a maximum torque of 102.0 Nm.

A non-positive shaft-hub connection with zero backlash can be achieved with the b of the MSK100B-0300-NN-S1-AG1-NNNN. This shaft has a shaft sealing designed per DIN 3760 - design A, and it prevents the entry of fluids into the motor via the shaft. The motor has four pole pairs and a rotor with a moment of inertia of 0.01920 kgm². It is cooled by natural convection, where heat elimination is done via transfer to the ambient air. Its thermal sensor is of the KTY84 type, and it works with another temperature monitoring system called the temperature model to prevent damage to the motor by thermal overload. There is also an electrically released holding brake in this MSK motor.
