 1.3.2 Mechatronic motion modules
Mechatronic motion module (MMМ) is a constructively and functionally 
independent product, including mechanical, electrical (electronical) and infor-
mation parts that can be used individually and in various combinations with 
other modules.
In connection with the development of new electronic technologies that 
allowed the creation of miniature sensors and electronic units for processing 
their signals, electronic and information devices appeared in the mechatronic 
motion modules, which is their main distinguishing feature from the motion 
modules.
To create modern technological machines intended for automated machine 
building, a variety of mechatronic motion modules are needed that meet a 
number of requirements: high accuracy in implementing executive movements, 
reliability, durability, workability in the presence of various types of distur-
bances and a wide range of ambient temperatures, mass-size indicators in 
comparison with the usual electric drive.
Requirements for the development of efforts, accuracy and speed of execu-
tive movements are dictated by the features of the automated technological 
operation, and the requirement to minimize the dimensions of the mechatronic 
module of motion is the need to integrate it into the technological machine. An 
attempt to synthesize a mechatronic module of motion from existing commer-
cially available components can lead to technically and economically inefficient 
solutions.
Therefore, it is more rational to design a specialized mechatronic module of 
motion that most fully meets its official purpose. The complexity and inconsis-
tency of the requirements imposed on mechatronic modules of motion, makes it 
expedient to mechatron approach to their design.
In particular, following the principle of synergistic integration of the 
elements of the system leads to the achievement of the desired level of the 
module’s quality due to the constructive and functional interpenetration of its 
components, many of which are specialized and are created during parallel 
system design, taking into account their subsequent effective integration [9].
If the requirement to ensure the compactness of the mechatronic module 
of motion is predominant, then it can be realized by using contactless electric

machines and information measuring elements. In this case, the motion 
transducers and sensors are not separate devices, but become integral elements 
of the engine.
The synergetic effect is also achieved by performing several functions 
of the mechatronic modulus of motion of several functions simultaneously. 
Such solutions allow eliminating many mechanical interfaces, simplifying 
and reducing the cost of construction, eliminating the need for mechanical 
adjustment and matching of the sensor and the motor.
Mechatronic motion modules are functional «cubes» from which complex 
mechatronic systems can be arranged. Examples of mechatronic motion 
modu-
les:
mechatronic motion modules based on electric motors of angular and linear 
motion and various motion transducers (helical, worm, planetary, wave, etc.), 
gearless mechatronic motion modules, gearless rotary tables.
In 
Fig. 1.5
is presented the scheme of the mechatronic module of motion, 
developed in the Central Research Institute of Automation and Hydraulics and 
at MSTU «STANKIN» [2].
 
Figure 1.5 – Schematic diagram of mechatronic motion module
The module consists of a three-phase contactless electric motor, a ball screw 
drive transducer, an inductive position sensor (IPS) and guides. The rotor 6 of 
the electric motor is connected to the nut 2 of the ball screw drive transducer 
mounted on the bearings 3 in the housing 4. The currents flowing through the 
phase windings 7 of the stator 5 lead to the appearance of an electromagnetic

torque of the motor causing rotation of the nut 2. The screw 1 then linearly 
moves along the guides 8 To measure the movement of screw 1, an inductive 
position sensor 9 is used. The screw 1 plays the role of its movable element. 
The fixed part 9 is fixed in the housing 4 of the mechatronic module and is
