he new MS2N ser vo mo-

tor product line from Bosch

Rexroth, available throughout

sub-Saharan Africa exclusively

through Tectra Automation, covers the

torque range between 4.0 to 350 Nm

with significantly increased power density

and greater energy efficiency. In asso-

ciation 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 of every single mo-

tor, as well as the saturation and tempera-

ture 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 values that have been

standard up to now. For the first time,

Bosch Rexroth is meeting market requirements in the Industry 4.0 environment

for intelligent solutions combined with short cycle times and flexibility with its

newly designed IndraDyn S MS2N synchronous servo motor product line. Jaco

de Beer (right), project engineer for mechatronics at Tectra Automation explains.

Powerful MS2N synchronous servo motors have innovative single-cable connections

combined with IndraDrive control device data.

A new synchronous motor generation:

intelligent, powerful and flexible

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, such as condition monitor-

ing, can be realised cost-effectively and

without additional components.

Up to 30% higher torque density

The motors are significantly more com-

pact 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 cur-

rent drive tasks while more performance

is available within the prescribed motor

clearance. The up to five-times 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 m 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 4.0 Nm to 350 Nm

maximum torque performance range

and the 0.8 Nm to 148 Nm permanent

torque performance range. Alternate

variations, with higher rotor inertia for

better mass customisation, compliment

this extensive range and allow for precise

alignment of task formulation and motor

selection.

To supply power and the encoder

signal, Bosch Rexroth provides an in-

novative single-cable connection, as

well as conventional two-cable solutions,

with highly flexible cable variations and

a practical quick lock.

Both options enable a complete cable

length in the IndraDrive standard, which

means up to 75 m 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.

cialist providing solutions for industrial
