Twelve new variants of a compact synchronous servo motor are now available, offering high continuous power and an extended speed range to manufacturers.

Bosch Rexroth has announced that it is expanding the performance range of its MS2N engine series at the high end, with up to 692 Nm - the maximum torque has been almost doubled.

The company has increased the continuous power within the small installation space through optimised 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, namely self-cooling, force-ventilated or water cooling. With a continuous torque of up to 345 Nm and maximum speeds of up to 3 600 rpm, the motors are particularly suited for powerful applications in plastics processing machines, in forming technology or in heavy-duty machining.

The new motor series is said to be suited to a wide range of applications in automation and combines dynamics with compact dimensions and maximum energy efficiency. The motors can be configured flexibly, with a range of shafts, encoders and holding brakes available for designers to select, according to specific requirements. The company asserts that 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, allowing the motors to be integrated into the increasingly networked field level of the future. The company further states that the MS2N plays an integral part in maximising productivity in the new Bosch Rexroth Automation world, ctrlX AUTOMATION.

The motors are available in sub-Saharan Africa through Tectra Automation, a Bosch Rexroth South Africa group company.
