Bosch Rexroth: Twice as strong but still compact

November 13, 2019

With twelve new variants of the synchronous servo motor MS2N, Bosch Rexroth is expanding the performance range of the engine series at the high end. With up to 692 Nm, the maximum torque is almost doubled. These new, compact motors offer high continuous power and an extended speed range to manufacturers.

Bosch Rexroth has increased the continuous power within the small installation space through optimized electromagnetic design and use of the reluctance effect to create torque. The new frame size MS2N13 comprises four compact lengths in three cooling variants each: Self-cooling, forced-ventilated or water cooling. With a continuous torque of up to 345 Nm and maximum speeds of up to 3,600 rpm, they are particularly suited for powerful applications in plastics processing machines, in forming technology or in heavy-duty machining.

The motor series MS2N is a true all-rounder for all applications in automation and combines dynamics with compact dimensions and maximum energy efficiency. The motors can be configured flexibly, with a wide range of shafts, encoders and holding brakes to choose from. Designers can select them in line with the respective requirements. The integrated SafeMotion encoders with the high performance class SIL3/PLe make additional safety components in the machine redundant.

The encoders interact with drive controllers to work as sensors and collect the operational data of the axis. This way, the motors are integrated in the increasingly networked field level of the future. MS2N also play an integral part in maximizing productivity in the new Bosch Rexroth Automation world, ctrlX AUTOMATION.
