The modern level of development of the industry requires
creation of more difficult and high-precision
systems of an electric actuator allowing executing precisely
and correctly the given technological processes.
As these devices, we may consider hybrid or cascade
systems of an electric actuator. However, for creation
of such devices we require new design approaches, or
specification and improving of the existing theories and
methods of design of classical systems. The main difficulty
in calculation consists in determination of parameters
of electromagnetic system. In this article, new
approach is given in finding of electromagnetic parameters
of components of an asynchronous controlled
cascade electric actuator taking into account real geometry.
This approach was formed during creation of
the program complex, which is a part of a system of
automatic design
The current state of the industry and high level of development
of technologies dictates the requirements to
various electromechanical converters of energy and
electric drives. Constantly there are new requirements
to these types of devices and their characteristics that
lead to creation of more and more difficult devices of
the electric drive and control systems which example is
cascade systems of electric drives. This type of drives
solves part of problems of the modern industry. However,
creation of such devices requires development of
new approaches to design and creation of cascade systems
of the electric drive and its components where one
of the most complex challenges is determination of
parameters of electromagnetic system. In the article, a
new approach is given, in finding electromagnetic parameters
of components of the operated cascade asynchronous
electric drive, proceeding from the applied
types of the electric windings distributed in space. This
approach is realized at creation of the program complex,
which is part of system of automatic design
The problem of calculation of arguments of the controlled cascade electric drive is reviewed. For a basis the electric drive is taken by the designed writers. For definition of the moments the method grounded on electromechanical transforming of energy is proposed.
On an example of a present construction the values of currents of a stator and rotor and phase angles of these currents were retrieved. It has allowed to find the energy, accumulated by the device, in the given instant. Utilizing this result, the instantaneous moment was defined. The introduced mathematical model realized as the program in environment Delphi. Inaccuracy for an audit example did not exceed 10-15 %
Nowadays some branches of the industry need hybrid
or cascade systems of electric drives. Electric
drives use up to 60 percent of all developed electric
power therefore with improvement of massdimensional
indicators and power characteristics of
the considered devices necessary technical characteristics
are reached and losses of electric energy
decrease. When creating electric drives of various
designs, it is important and rather difficult to calculate
an electromagnetic system. Classical approach
to design of data of systems has a number of shortcomings
that demands creation of new approaches
or adjustment and addition of the known methods
and approaches. In the article, another approach to
design of the developed systems of the electric
drive is offered
The article presents the algorithm of the program for
calculation of distribution of a stream of the winding
of the stator of a component of the operated asynchronous
cascade electric drive. For the description of the
algorithm we have chosen a two-layer winding on
twenty four grooves. This algorithm is calculated on
receiving a picture of distribution of the stream of the
winding and, respectively, receiving a graphic representation.
The algorithm is constructed on a number of
the principles and types of calculation. On the principle
of the task of the design of the winding, for a possibility
of using this principle for further calculation.
On the procedure of calculation of a picture of distribution
of a magnetic field in a gap of a component of
the operated asynchronous cascade electric drive, according
to operation on his construction. On receiving
the pseudo-animation showing a picture of change of
the field in space at turn of three-phase system of currents
eventually
