Description
For different industries, there was a need of creation new equipment and mechanisms with enhanced characteristics. Special requirements are imposed to energetic and mass-dimensional indices of systems of electric drives as one of the main components of such devices. Mass-dimensional and energetic indices due to constructional features and the used management system will allow improving the use of special or controlled asynchronous cascade systems of an electric actuator of axial construction. One of the main difficulties is simulation and design of special systems of the electric drive. In the article, we offer a new approach to determination of magnetic model parameters of the stator of a component of a controlled asynchronous cascade electric actuator of axial construction

MATHEMATICAL MODELING OF SPECIAL ELECTRIC DRIVES FOR THE EQUIPMENT OF OIL AND GAS BRANCH
Description
Creation of new types of special electric actuators for the oil and gas industry implies development of new approaches to simulation, design of the considered types of electric actuators. In addition, it requires development of new algorithms for creation of a complex of application programs of computer-aided design of special electric actuators. As process of simulation is quite labor consuming, it is offered to realize it gradually. In this article, the question of mathematical simulation of special electric actuators for the equipment of oil and gas branch using methods of electromagnetic conversion of energy is considered. Results of mathematical simulation were realized in the form of the program products, which are a part of system of computer-aided design

Description
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

Description
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

Description
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

Description
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
