High-dynamic, precise and easy to configure – the latest developments in the motor spectrum from Bosch Rexroth follow these basic requirements for automation and electrification. Thanks to their high dynamics and force density, they enable the shortest cycle times in many applications. The high-torque synchronous servo motor, MS2N, is also available with an integrated encoder in the SIL3 PLe category for demanding tasks with SafeMotion. Also, in conjunction with IndraDrive control units, the MS2N motors can be used as a data source for I4.0.

Rexroth offers the IndraDyn S series MS2N in six sizes with up to five lengths each. The series covers the power range from 4 Nm to 360 Nm maximum torque and 0.8 Nm to 215 Nm continuous torque at standstill. Machine manufacturers can choose from three encoder systems, all finely graded in both precision and resolution. For the electrical connection of power and encoder signal, Rexroth provides an innovative single cable connection, as well as conventional two-cable solutions with highly flexible cable options and practical quick-lock.

Thanks to the new motor construction and an optimized electromagnetic design, this new generation is able to achieve significantly reduced torque ripple. This is especially important for maintaining constant path velocity and increased product quality. In addition, the developers at Bosch Rexroth have reached up to 30 percent higher torque density. The motors are significantly more compact despite their enhanced performance. Therefore, machine manufacturers can use smaller motors in existing drive tasks or use more power within a given motor compartment. Up to five times overload capacity guarantees the fastest acceleration and optimum dynamism for all sizes. With different degrees of rotor inertia, machine manufacturers can offer application-oriented design for different masses on the axes.

Due to high-quality materials, the MS2N motors achieve significantly greater continuous power, even at higher speeds. Also, thanks to their optimized winding technology, the motors help to reduce internal losses. Plus, the new generation accomplishes dramatic increases in energy efficiency.

The high-torque synchronous servo motor MS2N has proven itself in the Bosch Rexroth Connected Automation range with their high dynamic, synchronization and a robust single-cable connection, with up to 75 m cable length.

The servo motor is also available with an integrated SafeMotion encoder from the high-performance SIL 3, PL e safety class. This eliminates the need for additional safety components in the system. The motor model in the IndraSize engineering tool enables safe, quick and simple drive configurations that correspond exactly to real operation.

In the new IndraDyn S series MS2N, intelligence now reaches all the way up to the motor. Individual measurements of each individual motor, as well as saturation and temperature data, are stored in the respective motor's memory and are automatically processed by IndraDrive controllers. This information greatly increases the precision of the torque and reduces the tolerance range to a fraction of previously accepted values. Also, for the first time, the servo motor provides data as well. This feature allows OEM’s to implement Industry 4.0 applications, such as condition monitoring and predictive maintenance, economically and without additional components.
