New generation of synchronous motors
3rd Quarter 2016, Shaft power components
The newly designed MS2N synchronous servo motor range from Bosch Rexroth meets the requirements for intelligent solutions combined with short cycle times and flexibility in the Industry 4.0 environment. The MS2N product line is available throughout sub-Saharan Africa exclusively through Tectra Automation. It covers the maximum torque range between 4 to 350 Nm, with significantly increased power density and greater energy efficiency. In association with IndraDrive control devices, MS2N motors are becoming the source of data for tasks within the networked production plant.
With this in mind, Bosch Rexroth has opened up completely new application opportunities and has set new standards in servo drive technology. The MS2N product line is tailored to the demands of the future in both functionality and performance.
Individual readings from every single motor, as well as saturation and temperature data, are deposited into motor data storage and automatically processed by IndraDrive control devices. This increases torque precision significantly and reduces the tolerance range during operation to a fraction of the value that has been standard up to now. For the first time, the servo motor can be used as a reliable sensor as well as a data source. In this way, applications within the Industry 4.0 environment like condition monitoring can be realised cost-effectively and without additional components.
Up to 30% higher torque density
The motors are significantly more compact, despite their higher performance. With a new motor construction, and optimised electromagnetic design, this new generation of motors achieves up to 30% higher torque density. This has two effects for machinery manufacturers: smaller motors can be employed for current drive tasks, while more performance is available within the prescribed motor clearance. The up to five-time overload capacity with persistently low rotor inertia guarantees the greatest possible acceleration and dynamics in all sizes. Thanks to high grade materials, this new development also makes it possible to have continuous output within higher rpm ranges; and along with optimised winding technology, it also reduces internal losses. In the process, the new generation of motors achieves significantly improved energy efficiency and provides a sustainable reduction in operating costs.
Up to 75 metres with one cable
The highly dynamic MS2N product line comes in six sizes, with up to five lengths available in each. The product line covers the 4 to 350 Nm maximum torque performance range and the 0,8 to 148 Nm permanent torque performance range. Alternate variations with higher rotor inertia for better mass customisation complement this extensive range and allow for precise alignment of task formulation and motor selection. There are three corresponding, differentiated encoder systems.
To supply power and the encoder signal, Bosch Rexroth provides an innovative single-cable connection, as well as conventional two-cable solutions, with highly flexible cable variations and a practical quick lock. Both options allow a complete cable length in the IndraDrive standard, which means a cable of up to 75 metres with no additional components is possible. In this way, both types of connections can be combined with one another at minimal cost. The equipment wiring is no longer subject to the limitations of previous single-cable systems.
